Study on seismic behavior of concrete composite bearing wall

Two concrete composite bearing walls were tested under low cyclic reversed lateral loading. The behavior such as deformation process, failure mechanism, hysteretic characteristic, ductility, energy- dissipation capacity and curve of stiffness degradation was studied. In the mean time, working performance of the prefabricated slabs and frame were investigated. The test results revealed that the prefabricated slabs and frame could work in coordination very well, they could form two seismic fortifications. The wall has good load-carrying capacity, seismic behavior and ductility. Besides, the load-carrying capacity and ductility of the wall connected with horizontal muscle is better than the other group. 1 FOREWORD The concrete composite bearing wall is different from brick wall and common concrete wall, this pa- Energy saving of the residence and replacement of per mainly introduce about loading process, craze in- the bricks are hot issues of the construction industry. stance, failure process, the hysteretic characteristic, A new type of wallboard is designed in this paper, ductility, energy-dissipation capacity, curve of stiff- which is called the concrete composite bearing wall. ness degradation and research harmony work of the The wall mainly composed of prefabricated slabs prefabricated slabs and frame by experiment and with polystyrene inside and contact framework is the analysis of finite element. main strength component of the concrete composite bearing wall housing.
