A review of satellite positioning systems for civil engineering

A review of satellite positioning systems for civil engineering

Figure  11 illustrates the results from carrying out a power spectral density analysis of the vertical data over a 5 min period. It  can be seen from Figure  11 that there is a fundamental frequency of 0·1416 Hz in the vertical direction from these data. These results help to illustrate the possibilities using kinematic GPS. These types of data rates and precisions could be re-produced in other civil engineering scenarios, such as construction plant control, land surveying and setting out and deformation monitoring of other types of man-made and natural structures.

Civil Engineering: A Surprisingly Noble Career

Civil Engineering: A Surprisingly Noble Career

Civil engineers will always be needed. As society grows, the demand for structures will grow as well. Along with the building of new structures, the inspection of existing structures will always be needed. In his article “Mega-Engineering” in Popular Mechanics, Davin Coburn states, “The economy may be struggling, but there is still plenty of work to be done in America. Aging Bridges need to be replaced, ships need building, energy needs to be produced” (61). Also, in the past fifty years the world has seen incredible advances in the area of science and technology. With these progressions, new systems and structures are needed to be designed and built. An article published by Tech News Daily, a poplar and respected online scientific news source, states, “Thanks to new technologies and new testing methods, some of today's largest buildings can stay safe in a quake without compromising their size or aesthetic design. In fact, to attain their great height, many of the world's largest buildings utilize architectural elements that also protect them in case of disaster” (“The World’s 7…”). These earthquake resistant buildings could save thousands of lives, which shows the value and usefulness of civil engineering.

Application of geophysical methods in civil engineering

Application of geophysical methods in civil engineering

Since such potential of geophysics in engineering are yet to be realized, the application of these techniques are still not being fully utilized. Problems may arise during the applications when the geophysical methods are not being fully explored by the civil engineers due to their lack of exposure and expertise in this field. According to [1], some of the reasons are due to poor planning of geophysical survey by engineers whom are ignorant of the techniques, and over optimistic geophysicist leading to poor reputation of the available techniques. Hence, this paper presents several case studies regarding the studies of resistivity and seismic method, which can be adopted and applied in civil engineering works.

The capacity of emerging civil engineering contractors

The capacity of emerging civil engineering contractors

engineering contractors It is notable that the greatest difference between MSs is relative to scheduling, developing policies, establishing relationship, decision- making and developing people. In general it is also notable that unsuccessful emerging civil engineering contractors rate their man- agement’s competencies more adequate than successful emerg- ing civil engineering contractors do, however, not relative to the function of organising. This higher percentage may be attributable to a lack of understanding of the actual activities and related com- petencies, and or an overestimation of adequacy. Furthermore, this could also be construed to be a lack of appreciation of limitations. Table 7: A comparison between successful and unsuccessful

Integrating ACAD with GIS for Civil Engineering Applications

Integrating ACAD with GIS for Civil Engineering Applications

GIS is a computerized database management system that provides geographic access (capture, storage, retrieval, analy- sis and display) to spatial data. Civil Engineering projects involve the management, analysis and integration of large amounts of geographic information to ensure success. This can include a wide range of information such as detailed design drawings originating from CAD solutions, detailed mapping, air photography, geological investigations, popula- tion information, traffic flows and environmental models. Although there are some similarities between CAD and GIS there are many differences. The most fundamental difference is that GIS mode is the world as it exists, whereas CAD models artifacts yet to be produced. As a result the data manipulated by a GIS is an order of magnitude larger and more complex than CAD systems have to deal with, and the nature of the data, its sources and its uses are quite different. In this paper, the selected area was Nahrain University. Many data were saved on the site map as a transparence layers built by using AutoCAD (2006). Then a digital library was built for the selected area and many data were saved on the site map as a themes built by using ArcView software.

SEISMIC FRAGILITY OF A CIVIL ENGINEERING STRUCTURE

SEISMIC FRAGILITY OF A CIVIL ENGINEERING STRUCTURE

Seismic fragility of civil engineering structures are generally evaluated by analysis. The structure is an assemblage of a number of elements like beams, columns, slabs etc. Civil engineering structures are complex with high degree of indeterminacy wherein the failure of one element may not cause total failure of the structure. One approach to address this concern is consideration of lateral deflection of the structure or inter storey drift in derivation of seismic fragility. Calculation of seismic fragility adopting deflection parameter can be accomplished by conventional method using results of elastic analysis or deflection based analysis technique like pushover analysis. Fragility analysis of civil engineering structure adopting deflection parameters is illustrated by an example problem of a representative bay from a RCC framed structure of a nuclear facility. Seismic fragility determined adopting the conventional element strength based approach, the conventional approach considering deflection parameter and using pushover analysis technique are compared.

Sustainable Practices in Civil Engineering Laboratories

Sustainable Practices in Civil Engineering Laboratories

Training the lab staff in proper use of the available facilities is another area of sustainability. Short term training modules arranged by the Department and the intercollegiate training programmes are also so helpful in this regard. “National Institute of Technical Teachers Training and Research” (NITTTR), Chandigarh under Ministry of Human Resource Development (MHRD), Government of India, is a well-known establishment in Training and Research. Civil engineering lab demos prepared by them are available in the internet By observing these programmes, lab staffs cantrain themselves and improve/ update their skill. At the beginning of each semester, teachers update on the instructions to be given to the students.

Application of Artificial Neural Networks in Civil Engineering

Application of Artificial Neural Networks in Civil Engineering

Artificial neural networks are computers whose architecture is modeled after the brain. In other words it is a computational system inspired by the structure, processing method and learning ability of a biological brain. They typically consist of many hundreds of simple processing units which are wired together in a complex communication network. Each unit or node is a simplified model of a real neuron which fires (sends off a new signal) if it receives a sufficiently strong input signal from the other nodes to which it is connected. An artificial neural network (ANN) is applied to several civil engineering problems, which have difficulty to solve or interrupt through conventional approaches of engineering mechanics. These include tide forecasting, earthquake-induced liquefaction and wave-induced seabed instability. ANN model can provide reasonable accuracy for civil engineering problems, and a more effective tool for engineering applications. A natural disaster is the effect of a natural hazard (e.g., flood, tornado, hurricane, volcanic eruption, earthquake, heat wave, or landslide). Earthquakes, landslides, tsunamis and volcanoes are complex physical phenomenon that leads to financial, environmental or human losses. Also, prediction of these disasters is a complex process that depends on many physical and environmental parameters. Many approaches exist in the literature based on scientific and statistical analysis. Data mining techniques can also be used for prediction of these natural hazards. Unfortunately, successful earthquake predictions are extremely rare. There are two basic categories of earthquake predictions: forecasts (months to years in advance) and short term predictions (hours or days in advance). Forecasts are based a variety of research, including the history of earthquakes in a specific region, the identification of fault characteristics (including length, depth

Mentoring undergraduate civil engineering students

Mentoring undergraduate civil engineering students

Assisting with the continuing personal development (CPD) of others, particularly the initial professional development (IPD) of graduates, typically occurs within an organisation ’ s ICE-approved training scheme under the guidance of a supervising civil engineer. Although Steels ’ guide, Dynamic Mentoring for Civil Engineers (Steels, 2001), is of assistance in this matter, there appears to be a paucity of guidance and empirical research regarding graduate (alumni) – student mentoring, the topic of this paper. However, the initiative of Chrisp and Fordyce (1993) at Heriot Watt University in Edinburgh provides some direction. First-year civil engineering students were mentored by professional engineers termed industrial liaison of fi cers (ILOs). Their paper is somewhat ambiguous as to whether the student mentees ventured into the fi eld but it appears that the ILOs visited the university. More recently, Davies and Rutherford (2012) reported on an initiative that used students studying civil engineering on a part-time mode acting as mentors to their full-time student mentees.

Civil Engineering Materials

Civil Engineering Materials

Civil Engineering Materials covers all major traditional civil engineering materi­ als through separate chapters. Sustainability is an important consideration these days among civil and construction engineering professionals. It is and will be a critical element in the material selection process. Chapter 13 discusses the sustainability, life cycle analysis, and othet important issues relevant to civil and construction materials. The civil engineering materials course is almost always taught in a broad-brush approach rather than providing comprehensive coverage. Generally, students learn the subject in the early years of a civil engineering program, and with the content covering a wide range of rather independent topics, it is necessary to provide a broad-brush treatment without relying on too many prerequisites. The students sub­ sequently take more detailed courses in soils, rocks, concrete, steel, etc. that offer higher-level coverage.

SMA for Dampers in Civil Engineering

SMA for Dampers in Civil Engineering

To increase the life quality is one of the main goals of smart materials and systems. The actual development of smart systems 1) in damping on sky-scrapers, high towers and stayed cables in bridges uses, for instance, magnetoreological fluids with semi-active systems. These, and similar devices, need supervision and maintenance, which might be inappro- priate for relatively small constructions. In Mechanical and Civil Engineering three different kinds of oscillation phe- nomena can be considered. First, repeated or ‘‘continuous’’ oscillations with different amplitude scales as wind and rain induce in large structures (sky-scrapers, high towers and stayed cables in bridges). Second, scarce groups of waves in relative short time applications (i.e., one or two weeks) as in satellite launching and third the situation induced by earth- quakes: scarce groups of large waves after several years of inactivity.

APPLICATION OF INFRARED THERMOGRAPHY IN CIVIL ENGINEERING

APPLICATION OF INFRARED THERMOGRAPHY IN CIVIL ENGINEERING

Infrared thermography is a powerful tool to investigate structural condition and equally useful for damage assessment. It is a non-contact and non-destructive method that enables rapid investigations. Highly efficient infrared cameras and versatile software have simplified thermography considerably over the years While infrared thermography has wide applications in process industries, it is not yet extensively adopted in the investigation of buildings. The paper presents a brief historical account of infrared thermography, the phenomenon of electromagnetic radiation, thermal imaging and applications in civil engineering.

Mentoring undergraduate civil engineering students

Mentoring undergraduate civil engineering students

Abstract: On enrolment at university, undergraduate civil engineering students begin their journey towards a professional career. Associating with graduate engineers throughout their studies provides students with potential role models and assists them to accustom progressively to the industry. Whilst the procurement of guest practitioners to deliver workshops and lectures remains buoyant, opportunities for students to secure summer placements within the civil engineering sector, has been problematic since the 2008 financial crisis. Graduate mentoring of student mentees can help to bridge the shortage of vocational placements. This paper discusses the results from a graduate mentoring initiative involving third year (n=345) civil & environmental engineering (CEE) student mentees, 83 graduate mentors and 31 employers. The results show that the student mentees overwhelmingly support and validate the opportunities that this initiative has provided. On completion of their mentoring meetings, and on return to their fourth year of their studies, the majority of the students commit to making behavioural and attitudinal changes regarding their own continued professional development (CPD).

Examples of categorization of seismic load for civil engineering and mechanical engineering

Examples of categorization of seismic load for civil engineering and mechanical engineering

Mechanical engineers are very familiar with the concept of primary and secondary stresses. However, as oppose to civil engineers, they are reluctant to consider the primary part of a seismically- induced stress, likely because they have doubt about how to calculate it. As it provides a rational way for such a calculation, we hope that the procedure presented in this paper will facilitate establishing a practice consistent with the physical phenomena that control the seismic response of piping systems.
