In this study the fire test was performed to investigate mechanic behaviors and failure patterns of precast normal weight concrete (NWC) lightweight (LWC) walls with three types commonly used steel connectors, namely dry (61), wet (81), bearing (56E) connectors. For LWC wall specimens, on lateral application tension, cracking load values dry, wet, bearing-type connectors were 95.1%, 86.3%, 83.0...

At present, most precast shear walls are implemented in accordance with the method equivalent to a cast-in-place structure, where joint is complicated, and construction difficult. According characteristics of wall structures, design “strong horizontal joints, weak vertical joints” for structure proposed. The existing was used form strong damper connect joints joints. It can reduce pouring concr...
