为研究该结构的抗震性能，对1:3比例的限芽钢板剪力墙半刚性钢框架进行振动台试验。该模型设计为普通钢板剪力墙，但具有屈曲约束。其成员由非简化部分组成。还介绍了测试样本、仪器、设置程序的描述。分析了动态特性、加速度、位移和剪力。弹性塑料的最大层间偏角为1/68。满载时侧向刚度下降仅为12%。测试模型在罕见地震下并未倒塌。结果表明，其抗震性能足以在大地震激励下生存，构件和半刚性连接的设计方法合理。
A shaking table test of a 1:3 scale semi-rigid steel frame with budding-restrained steel plate shear wall was conducted herein to study the seismic performance of this type of structure. The model was designed as ordinary steel plate shear walls, but with buckling-restrained. Its members consisted of non-simplified sections. The descriptions of the test specimen, instruments, set-up procedures were also presented. The dynamic characteristics, acceleration, displacement, and shear force were analysed. The maximum inter-storey drift angle in elastic plastic was 1/68. The lateral stiffness drop was only 12% when completely loaded. The test model did not collapse under rare earthquakes. The results showed that the seismic behaviour was adequate for survival in large seismic excitations, and the design methods of the members and the semi-rigid connections were reasonable.
