Abstract

Based on the traditional ecological composite wall, expanding composite wall is put forward in this paper. Based on the tests of five pieces of 1/2 scaled expanding composite wall under low-cycle lateral loading, the bearing capacity, ductility, hysteretic characteristics, and stiffness degradation performance of the walls are analyzed. The results show that, all the five pieces of wall are subjected to shearing failure which are ideal failure modes, they all come through elastic, elastic-plastic and failure stage. Because of different constrained types, the damage processes of different walls are different during the test process. Frame, ribs and concrete blocks are under reciprocal bond, which results in improving the bearing capacity of the wall, keeping the wall from cracking, and giving full play to their energy-dissipating capacity. L-type light steel keel rib and C-type steel frame can significantly increase the constraint on blocks, effectively limit the development of wall cracks, and greatly improve the seismic performance of the walls. EPS lightweight aggregate wall block can improve the ductility of the wall without reducing the ultimate bearing capacity.
