Abstract:

In order to adopt substructure pseudodynamic aseismic test method in frame supported reinforced concrete block masonry shear walls building, the design and construction of a 1∶4 scale frame supported reinforced concrete masonry shear walls building are investigated. The dimensions effect, details measure, installation term，and outlay condition are considered. The results of the material mechanics performance used by model building are analyzed and compared with the theoretical solutions. It is shown that the 1∶4 scale model building can respond the dynamic characteristic of the prototype building completely. Based on the dynamic similar principle, the member section and reinforcement of prototype building are converted into 1∶4 scale model building"s. Moreover, the materials and construction methods are introduced.

Keywords:reinforced concrete block masonry; framesupported shear wall; 1∶4 scale testing model building
