in this paper, full scale load test of a horizontally curved steel box-girder bridge is carried out in order to detect structural defects, which reportedly result in unwanted vibrations in nearby buildings. the bridge is tested under the passage of six heavy vehicles at different speeds, so as to determine its static and dynamic responses. a total number of one hundred and two (102) sensors are...

Near field earthquakes have imposed major damage to buildings in the past years. In some cases, the intensity of such damage is too considerable to be disregarded. The most effective way to improve seismic performance of buildings is applying a seismic control technique. The cylindrical friction damper is one of these methods, which has become popular for its desirable performance in the energy...

Seismic rehabilitation provides existing buildings with more resistance to seismic activity, ground motion, or geotechnical failure due to earthquakes. Performance-based rehabilitation is a general concept through which the retrofitting criteria are defined regarding to performance objectives when the structural and nonstructural members are subject to different levels of earthquake hazards. In...

In this study, we discussed the effects on the thermal comfort of super high-rise residences that how effected by the high thermal capacity structural components. We considered different building orientations, structures, and insulation methods. We used the dynamic simulation software THERB (simulation of the thermal environment of residential buildings). It can estimate the temperature, humidi...

Steel piles below high-rise buildings may carry larger varying axial force generated by the overturning moment than those low- or medium-rise buildings. On top of that, subgrade lateral stiffness reduces drastically due to soil liquefaction during a significant earthquake. pile’s horizontal strength decrease lower position inflection point. In this paper, centrifugal tests superstructure with h...

Passive protection systems based on the use of metal shear panels represent an effective way for achieving a significant improvement of the seismic response of buildings. Nevertheless, the dissipative capacity of these devices could be limited by buckling phenomena. In order to reduce the influence of instability, "Buckling Inhibited Shear Panels" have been recently introduced as an innovative ...

In this paper, the strip model developed by others and implemented in a Canadian Standard to model steel plate shear walls (SPSW) is used to develop, investigate, and quantify, through plastic analysis, the various possible collapse mechanisms of SPSW. Comparisons of experimentally obtained ultimate strengths of steel plate shear walls and those predicted by plastic analysis are given and reaso...

Cross-bracing (X-bracing) is one of the most popular methods of seismic retrofitting, and has been shown to significantly increase the structural stiffness and strength of buildings. Conventional steel X-bracing methods typically exhibit brittle failure at the connection between the brace and the building, or buckling failure of the braces. This study investigated the structural properties of a...

seismic retrofit of masonry slabs in existing steel or masonry buildings has found special significance in current codes as failure of unstable jack arch slabs has been reported as a major reason for collapsing structures in middle east deadly earthquakes. in this paper, three retrofit schemes are investigated and compared. the proposed rehabilitation techniques consist of a single x strapping,...
