Seismic behaviour of RC slab–shear wall assemblage using nonlinear static and dynamic analyses

Abstract

Extensive research has been carried out in the past on the behaviour of shear walls for earthquake loading. The junction region of reinforced concrete (RC) wall and floor slab in multistoried buildings plays an important role in transfer of forces to the wall during earthquake shaking. However, extensive investigations on seismic behaviour of structural wall–slab assemblage have not been carried out. In the current study, the possible seismic response of an exterior shear wall–slab junction is investigated through nonlinear static and dynamic analyses of RC wall–slab assemblage. The stresses developed in the wall–slab junction are monitored to investigate the tensile damage. Nonlinear static analysis showed higher values of stresses and tensile damage at the junction region than the dynamic analyses under the selected ground motions.
