This paper presents a new configuration for semi-supported steel plate shear walls to increase their efficiency. For this purpose, the infill is proposed be trapezoidal shape instead of rectangular one. To find most efficient inclination angle lateral sides, numerical parametric study was conducted. Five different values including 60, 75, 90, 105, and 120 degrees were considered. Furthermore, t...

This paper describes the prototype design, specimen design, experimental setup, and experimental results of three light-gauge steel plate shear wall concepts. Prototype light-gauge steel plate shear walls are designed as seismic retrofits for a hospital structure in an area of high seismicity, and emphasis is placed on minimizing their impact on the existing framing. Three single-story test spe...

According to the different construction forms of PBL shear connectors in steel-concrete composite beam and steel-concrete joint section, eight finite element models in two groups of the two construction forms are conducted to study different mechanical properties of PBL shear connectors. Following conclusions can be drawn from the finite element method calculation results. The load-slip curve, ...

the combination of flexural frame and shear wall is one of the suitable systems to apply in reinforced concrete buildings. the deflections of flexural frame become limited due to the high stiffness of wall and the interaction of these systems. tall buildings even higher than fifty stories can be designed by using frame- wall systems. with respect to special behavior of flexural frame or shear w...

NingBo-Liansheng International Commercial Plaza is a twin towers with high-connection. It is a complex tall building. The frame-shear wall structure system is used. The connection body is in 21 and 22 layers. The connection system is strong connection and the two storey steel trusses are used. The north and South towers are placed by certain angle, and it designed for the adjustment of plane wi...

Although studies on RC beams under shear have a history record of more than 100 years, many important&#10issues in this context still remain that have evaded attention. The aim of the current study is to study a number of these less investigated aspects of the behavior of RC beams under shear. For this purpose, and based on the modified compression field theory, a computer program has been writ...

Bridges are often built in locations susceptible to multiple extreme hazards. Meeting some or all of these constraints drives the development of innovative multi-hazard design concepts. This paper presents the results of research conducted to develop and experimentally validate such multi-hazard bridge pier concepts. The first concept is a pier-bent made of concrete filled steel tube columns. F...

For this purpose a finite element model specifically developed for the nonlinear analysis of steel-concrete composite beams is adopted. This finite element model includes material nonlinearity of slab concrete, reinforcement steel, beam steel as well as slabbeam nonlinear partial interaction due to the deformable shear connection. The inclusion of the partial interaction in the composite beam m...
