This paper suggested a new connection protocol, adding cover-plate between shear links and column, which was used to enhance moment and shear carrying capacity of beam, relax the restriction and assure the sufficiency development of plastic deformation of the link, and dissipate more earthquake energy. Considering the scale ratio of 1:3, the experimental data was achieved by a specimen under cy...

External installation of steel braces is an effective approach to increase the lateral load resistance moment-resisting frames. However, effects existence on robustness frames resist progressive collapse still not clear because little study has been carried out. To fill this gap, in paper, six multistory subframes (three bare and three braced frames) were fabricated tested. Test results indicat...

Numerous studies were contemplated on the structures with distinctive structural configuration and ample amount of work is currently being performed through investigation response individual behavior shear walls bracings by varying configurations their material properties. Seismic design philosophies had mentioned firmly that a structure must accomplish Life Safety Performance Level for both re...

Worldwide, high rise construction is recent trend in the building development. Steel has many advantages which includes flexible framing system, assembling, less weight to height ratio, availability and it doesn’t harm environment. That’s reason steel been mostly used material buildings. Previously gravity load was considered as an important factor design. With demand of buildings now seismic f...

The primary seismic force-resisting system (SFRS) in middle- to high-rise reinforced concrete (RC) building structures often includes coupled shear walls (CSWs) and single (SSWs). These are designed transfer lateral forces the foundation dissipate energy through development of plastic hinges. latter lead residual displacement these structural components. On other hand, self-centering systems en...

The cold-formed steel-framed shear wall sheathed with steel sheet is widely used as a lateral force-resisting system for light-framed construction. However, the boundary conditions of screw joint are not clear when screwed to frame. To address this issue, experimental methods have been calculate strength, but these many limiting factors. In study, we investigate structural performance integrate...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

Composite steel shear wall is a lateral load resisting system which consists of a steel plate with concrete wall attached to one or both sides to prevent it from elastic buckling. The composite behavior is ensured by utilizing high-strength bolts. This paper investigates the effect of distance between bolts, and for this purpose 14 one-story one-bay specimens with various bolts spacing were mod...

Reinforced concrete walls are commonly used as the primary lateral-force-resistingsystem for tall buildings. As the tools for conducting nonlinear response history analysis have improved and with the advent of performance-based seismic design, reinforced concrete walls and core walls are often employed as the only lateral-force-resisting-system. Proper modeling of the load versus deformation be...

The dry frictional contact between two solid surfaces is well known to obey Coulomb friction laws. In particular, the static friction force resisting the relative lateral (tangential) motion of solid surfaces, initially at rest, is known to be proportional to the normal force and independent of the area of the macroscopic surfaces in contact. Experimentally, the static friction force has been o...
