摘要:
为了研究基于新材料（淤泥质陶粒发泡混凝土）、新构造形式（U型槽砌块加强肋）的复合墙体的抗震性能及不同加强肋对墙体的影响，设计了两榀配筋砌体墙并通过拟静力试验检验了其抗震性能，结果表明：陶粒粉煤灰砌块砌体墙具有较好的变形能力和耗能性能；双加强肋墙体（W-2）在承载力、刚度和耗能等抗震性能指标较单加强肋墙体（W-1）均有不同程度的增强，但延性略低于单加强肋墙体；因此，淤泥质陶粒发泡混凝土配筋砌体墙具有良好的承载力、刚度、延性、耗能等性能，可满足实际工程需要
Abstract:
In order to study the seismic performance composite walls with new material (Muddy ceramic foam concrete)and new forms (reinforcing ribs in U-block), two specimens of 1/2 ratio of composite walls with reinforcing rib in U-block under cyclic loads are desingned in the paper. Results show that the wall went through three stages i.e. elastic stage, elastoplastic stage, destruction phase. The final destruction takes the form of shear destruction, and the failure mechanism is reasonable. Double reinforcing rib composite wall (W-2) is better than the single reinforcing rib composite wall in strengthening capacity, stiffness and energy dissipation of the seismic performance indicators (W-1) in varying degrees of increase, with slightly lower ductility than single reinforcing rib composite wall; but with no collapse phenomenon in the whole course of the experiment. Mucky ceramic foam concrete block composite walls with reinforcing ribs have better seismic performance, which provide basis for application of multilayer composite wall structure of the house.
