Experimental Study On Seismic Behavior Of Concrete Walls Combined With Insulating Forms

The structural system of concrete bearing wall combined with insulating forms as heat-proof layers is a new type energy saving structural system of the bearing wall. In this thesis, the experiments are carried out to study on the seismic behavior of 10 specimen of the system under the cyclic loading. On the basis of the experiments, failure characters and hysteretic behaviors are analysed and the data of the load carrying capacity, stiffness, ductility and measurement of energy dissipation etc. are acquired. The major factors of the experiment are listed as following: the influence of different reinforcement ratio of the walls, the influence axial compression ratio, the influence of vertical reinforcing bars at the boundary, the influence of mortar layers etc. Furthermore, the load carrying capacity and the elastic stiffness are calculated and experimental results have proved that they are good. Finally the concrete suggestions are induced and brought forward.It is shown that the specimen with vertical reinforcing bars at the boundary have good seismic behaviors.
