dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

The over-strength coefficient is one of the key factors for seismic safety a structure. For RC frames, infill wall may improve lateral bearing capacity, while demand increases as well, which leads to unexpected performance an infilled frame in past earthquakes. Therefore, it necessary systematically study effect frames from point capacity and demand. In this paper, 36 structures with/without wa...

Six RC short-limb shear walls with an L-shaped section, constructed high-strength rebar and concrete, were loaded to destruction pseudo-static loading. Experimental results discussed compared horizontal in detail. Different failure modes obtained, such as flexure-dominated for specimens aspect ratio of 2.8 2.15 bending-shear 1.75. With a decrease the ratio, ductility decreased, whereas increase...

A new type of strengthening technique for existing reinforced concrete (RC) shear walls was proposed using steel wire mesh (SWM) and polymer mortar. The experimental campaign consists testing one conventional RC wall specimen four specimens strengthened different configurations ratios wrapping methods under cyclic lateral loading. results showed that the application meshes mortar not only delay...
