EXPERIMENTAL RESEARCH ON SEISMIC BEHAVIOR OF LOAD-BEARING WALL WITH COMPOUND INSULATION CONCRETE BLOCKS

A new set of compound masonry blocks that feature heat preservation has been designed and a new wall construction method has been proposed.Walls applied with this method have a heat-preserving layer on the outside of their ring beams and construction columns.Eight full-size concrete compound heat-preserving masonry walls were tested under low cyclic horizontal loadings.The earthquake resistant performance indicators of the wall,such as damage process,hysteresis features,ductility,energy dissipation and rigidity deterioration were studied.According to the experiments,the walls constructed by the new method are similar to the traditional walls in terms of failure mode,hysteresis features,ductility,energy dissipation and rigidity deterioration.
