| Abstract | Reinforced concrete (RC) shear walls have been recognized as an effective structural member to resist lateral loading, especially in high seismic regions. In moderate seismic regions such as Thailand, design and detailing of RC shear wall is dictated by wind design demands rather than seismic design demands. Past studies have shown that Thailand is at higher seismic risk than one expected, although Thailand is located in a low to moderate seismic region and there has never been any severe earthquake damage history. In the recent past, the awareness level about the possibility of seismic hazard has risen as indicated in probabilistic seismic hazard map for Thailand (Warnitchai and Lisantono 1996). It is only recently (2004) that the seismic design requirements are included in building code of Thailand. Typical design practice of Thailand leads to poorly detailed RC shear walls. Low shear reinforcement in the web and very little confinement ratios in the boundary zones are salient features of such non-ductile RC shear walls. The current study focuses on this typical design practice of RC shear walls prevailed in low to moderate seismic region. A reversed cyclic quasi static loading test is conducted to assess the seismic performance of a large scale flexure-shear dominated RC shear wall specimen with an aspect ratio of 2. Strong coupling effect of flexure and shear responses is observed even though the shear strength is about 1.5 times the shear corresponding to the nominal moment capacity of the specimen. The final mode of failure is concrete crushing and the buckling of longitudinal reinforcement in the boundary zones. The experimental results have been compared with existing analytical study (Fiber model in Perform3D, Orakcal &Wallace, 2006). This comparison indicates that the negligence of coupling of flexure and shear responses can lead to unreliable predictions of ductility and energy dissipation capacity of flexure-shear dominated RC shear wall such as the one considered in this study |
