Experimental Study on Assemble-type Composited Wall

摘要

For assemble-type composited wall, 4 pieces of wall which are 1/2 scale models were made. By pseudo-static tests under low cyclic loading, the aseismic behavior indexes were compared and analyzed, including failure characteristics, bearing capacity, stiffness, deformation, ductility, energy dissipation and so on. The results showed that: the frame which composed by rib-beams, rib-column and invisible frame can restraint bricks bearing and crack developing; the structure failed beginning at brick, then rib-grim, ending at invisible frame, this course can be described that the structure had multi-defense lines to resistant earthquake, and every components were used efficiently. The framework curve changed gently from yield to failure, there was no mutation and no collapse, which means the wall had a good collapse resistant capacity.
