Abstract

Abstract

Low-cycle repeated loading tests were carried out on the single-story single-span CLB rocking wall which is equipped with CFD, hysteretic curves and skeleton curves were drawn, and the problem of stiffness degradation was investigated. Based on the test results, the main body of rocking wall equipped with CFD was not damaged significantly, and the damage mode of the specimen was mainly the fracture of the bamboo material at the upper joint and the pre-stressed reinforcement anchor plate. The delayed hysteresis curve of the specimen without setting the damper was approximately bilinear, and the hysteresis curve after setting the damper was "flag shaped". Moreover, with the reduction of the moment contribution ratio, the hysteresis curve became more and more full, and the specimen still had a good strength after undergoing secondary loading. Moreover, when the specimen was subjected to secondary loading without repair, the stiffness will decreased.

- cross-laminated bamboo(CLB),
