Abstract

See full text

An experimental system for out-of-plane seismic performance of a masonry block wall, comprising: a static test bed (1), a lateral limiting system disposed on one side on the static test bed (1), and a transverse load system disposed on the other side on the static test bed (1), a masonry block wall to be tested (401) being disposed between the lateral limiting system and the transverse load system. The experimental system also comprises a vertical load system disposed above a wall. Also provided is an experimental method using the experimental system for out-of-plane seismic performance of a masonry block wall, on the basis of a quasi-static test method, a horizontal reciprocating actuator is used to simulate an out-of-plane seismic load action; quarter-point loading is implemented by means of a multi-stage shear stress distribution apparatus, then a force is transmitted to a second screw rod (602), and the second screw rod (602) fits an out-of-plane uniformly distributed load into four horizontally-equidistant transversely-concentrated forces and transmits same to a test piece. The present invention has the characteristics of a clear force transmission path, uniform stress distribution, high experimental precision and an accurate result, such that the study of the out-of-plane seismic performance of a component is more accurate and reliable.
