Effect of Wind and Earthquake Loading on Telecommunication Tower

Effect of Wind and Earthquake Loading on Telecommunication Tower

Abstract: The telecommunication industry plays a great role in human societies and thus much more attention is now being paid to telecommunication towers than it was in the past. Telecommunication towers are tall structures usually designed for supporting parabolic antennas installed at a specific height. As telecommunication towers are the only means of enhancing both the coverage area and network reliability, more and more telecommunications towers are installed nowadays. The stability of towers post-earthquake or a cyclone is of great concern. Hence in the present study, a detailed analysis has been made on the behaviour of the telecommunication tower subjected to wind and seismic loads with varying the bracing system of towers. Gust factor method is used for wind load analysis. Conducted analytical study on effect of wind on telecommunication towers, for wind speed of 50m/s for four combination of bracing systems; Also studied the effect of earthquake loading on telecommunication towers using Modal analysis and Response Spectrum method, for seismic zones III, IV and V for all the four combination of bracing systems. The results of displacement at the top of the towers and stresses in the bottom leg of the towers are compared and the optimum bracing system is found.

Response of Multistorey Building with Rooftop Telecommunication Tower in Different Positions: An Approach To Efficient Case

mobile phone creates a vital role among us. For this, the network service provider expands their business by extending the coverage of their network. In urban areas, the scarcity of land is the major issue now days and companies are approaching to the rooftop telecommunication, since it resolves the land use and to extend the coverage by approaching the height. Since it was not acknowledged before that the telecommunication tower will going to install over the roof of the multistorey building. In this work, to overcome this issue that creates a negative effect over the parts of the building after installation, by the help of Staad pro software, a plan is selected and designed not according to tower need and then the tower is applied over the roof in different positions to analyze the parametric values and select a position that creates least negative effects under seismic zone IV.

Analysis of existing effectiveness and method to enhance the lightning, shielding and earthing protection schemes applied on the Parit Raja’s telecommunication tower system

It has been shown by field experiences that telecommunication towers are one of the preferential points for direct lightning strikes. This is mainly connected with the specific features of their construction where the presence of high telecommunication towers and their topographical location mostly at an open area or at hills. Because of high altitude of placing radio transmission antennas, lightning strokes to the structures supporting the antennas are relatively frequent.

Vibration Analysis of a Telecommunication Tower under Loading

Vibration Analysis of a Telecommunication Tower under Loading

models are adopted [2]. A usual solution to overcome this problem is the use of dummy structural bars to prevent the occurrence of the unwanted degrees of freedom. These bars, possessing a small axial stiffness, are generally employed to prevent the occurrence of structural mechanisms, enabling the use of standard finite element programs. A possible explanation for the structure stability is related to the semi-rigid, instead of the assumed hinged joint behaviour. In fact, most major steel tower constructors still rely on full-scale tests to determine which design and fabrication details can provide a good test correlation with the assumed simple truss model results. Cohen and Pemn [3] made the earliest contributions to the study of guyed towers. The result of the investigation on wind loading was presented as a set of charts that could be used to predict the drag loads produced by wind on various types of structures. They further presented a model that described the behaviour of a guyed tower. The mast was treated as a cantilever beam- column on elastic supports and the guy cables were considered to follow a parabolic profile. Dean [4] investigated the amplification of stresses and displacements in guyed towers when changes in geometry are included. Modelling the guys as bars, charts were developed that could be used to determine when advanced methods of structural analysis are required in the design and what modifications could be made to the analysis to obtain reasonable results.

TELECOMMUNICATION TECHNOLOGIES

TELECOMMUNICATION TECHNOLOGIES

Telecommunications have become the major part of our routine life. People make the use of radio alarm to wake up , through tv they get to know about traffic and weather updates, and perhaps telephone are used to call people round the world. Computers are used to check if they have emails or some other business documents delivered in the offices. These all above discussed are forms of telecommunications, and these all have become the important part of modern society. Telecommunication over a telephone line is called point- to-point communication because it is between one transmitter and one receiver.

Design and manufacture of a bed supported tidal turbine model for blade and shaft load measurement in turbulent flow and waves

Design and manufacture of a bed supported tidal turbine model for blade and shaft load measurement in turbulent flow and waves

The torque and thrust transducer is bolted to a 304 stainless steel shaft with a solid main section of 25.4 mm in diameter. For the fi rst 60 mm (on the side of the transducer) the shaft is hollow to allow the instrumentation cable to go through and exit at 45 to connect to the rotor of the slipring. The cable from the slipring stator is routed through the model to exit at the top of the hollow tower via a waterproof connector (shown in white in Fig. 1). The shaft is held in place by two spherical bearings (SKF 22206E and 22205E) suitable for the expected thrust load and allowing for potential angular misalignment. Selection was mainly driven by their internal diameter and the load and rotation per minute (rpm) ratings for these bearings are overspeci fi ed for the design condi- tions (summarised in Table 1). The two parts housing the bearings on either side of the shaft are rigidly connected by four 14 mm diameter solid 304 stainless steel rods (two of them are visible in magenta in Fig. 1). This ‘ cage ’ arrangement is stiff and ensures alignment between the two bearing housings while providing ac- cess to the slipring connections when the waterproo fi ng sleeve is removed.

Designing telecommunication service management systems

Designing telecommunication service management systems

the technologies being researched and applied within the management, and (c) the business models, and processes, which ultimately the management systems must support. Paradoxically, deregulation of the telecommunication industry has also led to increased co-operation between telecom service providers. Such co-operation is generally aimed at gaining access to global markets. Therefore another driving force for such co-operation is the requirement of interoperability and fair-trading amongst existing and newer providers and service providers e.g. Federal Communications Committee rules in USA. The requirements exerted by this increased competition between providers and the (paradoxical) co-operation of providers are greatly affecting the way telecommunication services are managed today and will be managed in the future. This need for greater interoperability across organisational boundaries, can also been seen as a consequence of the globalisation of telecommunication services, where global service delivery usually requires significant management system interactions across different telecommunication service providers. An example of such multi-telecommunication provider co-operation would be in the provisioning of Virtual Private Networks across several organisations and continent boundaries [Wade 2002, Lewis1999a]. Because of the ever-increasing business-to-business computing integration on the Internet and the growth of global markets, the need for inter-telecommunication provider co-operation is ever increasing.
