Performance Study for No-Tilt Condition of Bi-Angle Shape Skirted Footing in Clayey Soil Subjected to Eccentric Load

Performance Study for No-Tilt Condition of Bi-Angle Shape Skirted Footing in Clayey Soil Subjected to Eccentric Load

Abstract––In selected part of clayey soil region of Malwa (M.P.),where Black cotton (B.C.) soil is available up to a large extent of depth, normally footing rest on B.C. soil strata having low bearing capacity or on naturally compacted yellow soil strata having considerable bearing capacity. Environmental changes have great impact on the behavior and strength parameter of the clayey soil like B.C. soil or Yellow soil. Skirted footing in which vertical walls surrounds sides of the soil mass beneath the footing is one of the recognized bearing capacity improvement technique. Construction of vertical skirts at the base of the footing, confining the underlying soil, generates a soil resistance on skirt sides that helps the footing to resist sliding. Bi-angle shaped skirt in which vertical walls surrounds two adjacent sides of the footing is a special case of skirted footing. A model study has been performed to investigate the behavior of Bi-angle shape skirted footing resting on B.C. soil and Yellow soil, subjected to two way eccentric load resulting in Bi-axial bending of the footing. The study helps in evaluating performance of skirted footing. The difference between the settlement of near end and far end is known as tilt of diagonally opposite corners of the footing. The tilt of diagonally opposite corners of the footing is affected considerably due to presence of skirts. Skirts have been found to be helpful in reducing tilt due to eccentric loading.

Structural behaviour of precast lightweight foamed concrete sandwich panel (PLFP) with double shear truss connectors under eccentric load: preliminary result

Structural behaviour of precast lightweight foamed concrete sandwich panel (PLFP) with double shear truss connectors under eccentric load: preliminary result

Abstract. Recent years in Malaysia, precast concrete sandwich panel gained its popularity in building industries due to its economic advantages, superior thermal and structural efficiency. This paper studied the structural behaviour of precast lightweight foamed concrete sandwich panel (PLFP) with double shear truss connectors under eccentric load. Preliminary results were analysed and studied to obtain the ultimate load carrying capacity, load-deflection profiles and strain distribution across the panel thickness at mid depth. The achieved ultimate load carrying capacity of PLFP due to eccentric load from the experimental work was compared with values calculated from classical formulas (if it is more than 1 comparison) developed by previous researchers. Preliminary results showed that, the use of double shear truss connectors in PLFP was able to improve its ultimate load carrying capacity to sustain eccentric load and achieve certain compositeness reaction in between the wythes.

Structural behaviour of precast lightweight concrete sandwich panel under eccentric load: an overview

Structural behaviour of precast lightweight concrete sandwich panel under eccentric load: an overview

Eccentric load is compression force or end force. The maximum eccentric load refers to how much weight can be placed on top of the wall with buckling or crushing. When the load is applied on a solid wall with an eccentricity greater than t/6, the wall develops tension within a certain zone. The zone is shown in Figure 3.1. It is assumed that this portion of the wall cracks slightly at each joint, in compliance with the assumption of a no tension material. The geometry of the cracked section changes for different values of eccentricity of load application. It is therefore necessary to apply the principles of the basic approach to the remaining uncracked portion of the wall (Kuddus, 2010).

Effects of load magnitude, muscle length and velocity during eccentric chronic loading on the longitudinal growth of the vastus lateralis muscle

Effects of load magnitude, muscle length and velocity during eccentric chronic loading on the longitudinal growth of the vastus lateralis muscle

Recent studies have also reported longitudinal muscle growth in human muscles in response to eccentric loading (Duclay et al., 2009; Potier et al., 2009; Reeves et al., 2009). These studies used eccentric or combined (i.e. concentric and eccentric) contractions in their training protocols, but they did not isolate the possible independent mechanical stimuli that may affect the longitudinal growth of muscle (i.e. magnitude of the eccentric loading, the lengthening velocity of the fibers and the fiber length where the eccentric load is applied). Butterfield and Herzog (Butterfield and Herzog, 2006) have reported that both the magnitude of muscle fiber strain and magnitude of the generated muscle force during eccentric exercise might affect the longitudinal muscle growth. Furthermore, the titin- based stretch sensing and the role of titin as a mechanosensor in sarcomeres for initiating signaling (Lange et al., 2005; Tskhovrebova and Trinick, 2008) suggest an effect of lengthening velocity of the fibers for the longitudinal muscle growth. To our knowledge there are no studies in human that have investigated the longitudinal muscle growth by applying training interventions of controlled eccentric loading.

New options in the management of tendinopathy

New options in the management of tendinopathy

Abstract: Tendon injuries can be acute or chronic, and caused by intrinsic or extrinsic factors, either alone or in combination. Tendinopathies are a common cause of disability in occupational medicine and account for a substantial proportion of overuse injuries in sports. Tendinopathy is essentially a failed healing response, with haphazard proliferation of tenocytes, abnormalities in tenocytes, with disruption of collagen fibres and subsequent increase in noncollagenous matrix. The scientific evidence base for managing tendinopathies is limited. What may appear clinically as an “acute tendinopathy” is actually a well advanced failure of a chronic healing response in which there is neither histologic nor biochemical evidence of inflammation. In this review we report the new options for the management of tendinopathy, including eccentric exercises, extracorporeal shockwave therapy, injections (intratendinous injections of corticosteroids, aprotinin, polidocanol platelet-rich plasma, autologous blood injection, high-volume injections) and surgery. Open surgery aims to excise fibrotic adhesions, remove areas of failed healing and make multiple longitudinal incisions in the tendon to detect intratendinous lesions, and to restore vascularity and possibly stimulate the remaining viable cells to initiate cell matrix response and healing. New surgical techniques aim to disrupt the abnormal neoinnervation to interfere with the pain sensation caused by tendinopathy. These procedures are intrinsically different from the classical ones in present use, because they do not attempt to address directly the pathologic lesion, but act only to denervate them. They include endoscopy, electrocoagulation, and minimally invasive stripping. Further randomized controlled trials are necessary to clarify better the best therapeutic options for the management of tendinopathy.

Early structural remodeling and deuterium oxide derived protein metabolic responses to eccentric and concentric loading in human skeletal muscle

Early structural remodeling and deuterium oxide derived protein metabolic responses to eccentric and concentric loading in human skeletal muscle

The notion that ECC contractions produce greater force than CON contractions (thus implying the use of greater loads in RET program) has prompted some authors to suggest that ECC-type exercise could pro- mote greater muscle hypertrophy and strength gains compared to CON (Roig et al. 2009). Nevertheless, the influence of contraction mode upon the degree of hypertrophy is contentious (Wernbom et al. 2007; LaS- tayo et al. 2014) with some reports of ECC being supe- rior (Higbie et al. 1996; Hortob agyi et al. 1996, 2000; Seger et al. 1998; Vikne et al. 2006) and others showing similar hypertrophy (Jones and Rutherford 1987; Dun- can et al. 1989; Blazevich et al. 2007; Nickols-Richardson et al. 2007; Moore et al. 2012; Franchi et al. 2014). Although our previous findings support the observations of similar muscle hypertrophy induced by CON and ECC when matched for relative maximal load (Reeves et al. 2009; Franchi et al. 2014), we highlighted that the key difference between ECC and CON adaptations is in the specific architectural remodeling. Specifically, ECC training promoted increases in fascicle length (Lf), whereas CON preferentially increased pennation angle (PA) (M. V. Narici, M. V. Franchi and C. N. Maga- naris, submitted). These findings suggest contraction- specific hypertrophy: longitudinal muscle growth (i.e., Lf increase) primarily with ECC (Seynnes et al. 2007; Potier et al. 2009) due to the addition of new sarcom- eres in series (Williams and Goldspink 1971; Williams 1990; Lynn and Morgan 1994), and transversal hypertro- phy highly in CON, due to increases in PA reflecting the addition of sarcomeres in parallel (Gans 1982; Kawakami et al. 1993; Narici and Maganaris 2007). Fur- thermore, disparities in the regional distribution of changes in anatomical cross-sectional area (ACSA) were also found (Franchi et al. 2014). While ECC resulted in preferential hypertrophy in distal region of m. vastus lateralis (VL), CON did so in the midbelly. Therefore, distinct architectural and spatial adaptations dominate distinct physiological responses to CON versus ECC contractions.

Eccentric Connectivity Index and Detour Eccentric Connectivity Index – A Comparison

Eccentric Connectivity Index and Detour Eccentric Connectivity Index – A Comparison

In theoretical chemistry molecular structure descriptor or topological indices, are used to compute properties of chemical compounds. In this paper, we discuss two topological indices namely, eccentric connectivity index and connective eccentric index [4,5,8]. We define these concepts analogously using the detour distance in graphs. We study the differences between both these indices using some examples. We also derive the relation between these indices and the average eccentricity. Throughout this paper, graph means simple connected graph. A graph is a pair G:(V,E) where V is a finite non-empty set and E isa symmetric binary relation on V . The following definitions are taken from the book by Harary [6]. In a graph, G = (V, E), V (or V (G)) and E(or E(G)) denote the vertex set and the edge set of G, respectively. A graph G = (V, E) is trivial, if it has only one vertex, i.e. |V (G)| = 1; otherwise G is nontrivial. The number of edges incident with a vertex u is called degree of a vertex and is denoted by deg G (u).The complete graph on n vertices is denoted by K n and it is that graph in which there exist an edge between each

On Eccentric Digraphs of Graphs

On Eccentric Digraphs of Graphs

Buckley [4] defines the eccentric digraph ED G   of a graph G as having the same vertex set as G and there is an arc from u to v if v is an eccentric vertex of u. The paper [4] presents the eccentric digraphs of many classes of graphs including complete graphs, complete bipartite graphs, antipodal graphs and cycles and gives various interesting general structural properties of eccentric digraphs of graphs. The antipodal digraph of a digraph G denoted by A G   , has the vertex set as G with an arc from vertex v in A G   if and only if v is an antipodal vertex of u in G; that is   u v , = m G   .

Truly eccentric - I. Revisiting eight single-eccentric planetary systems

Truly eccentric - I. Revisiting eight single-eccentric planetary systems

We find four long-period candidate companions in systems where an eccentric planet is present. If confirmed, these bodies could be responsible for eccentricity excitation via the Lidov–Kozai mechanism (Kozai 1962; Lidov 1962). In particular, HD 7449b and HD 89744b are highly eccentric planets (e > 0.67) which we confirm to be genuinely eccentric singles. The presence of distant massive companions driving Kozai oscillations would explain the origin of the large eccentricities, though we note that the conditions required for such oscillations are stringent, e.g. the perturbing body must be inclined at i 39 ◦ with respect to the orbital plane of the planet(s).

Experimental Investigation into the Compressive Behavior of Steel Columns with Flange Jointsin Prefabricated Steel Frame Structure

X.C. Liu et al. proposed a type of bolted-welded beam-column joint for modularized prefabricated multi-rise and high-rise steel structures which maintained relatively good seismic performance [7]. Lárus H. Lárusson et al. conducted a study on prefabricated composite and modular floor deck panels composed of relatively thin-fiber reinforced concrete slabs connected to steel substructures. The system indicates that the composite construction concept offers flexibility in the assembly process, the ability to adapt to various load and boundary requirements, and efficient utilization of material properties [8]. Wei Jian Zhao et al. studied the properties of a column-to-wall connection in the prefabricated frame-shear wall structure. The results showed that the mechanical properties of the four prefabricated structures are similar to the cast-in-situ structure [9].
