一个两阶段的实验程序产生的全尺寸的两层钢板剪力墙减少梁截面连接和组合楼板，实验解决的可替换性填充板地震后和中间梁的抗震性能。在第一阶段，标本进行拟动力测试，受到三个地面运动的强度逐渐降低。在第二阶段，在将试样提交到随后的拟动力试验和循环试验直至失效之前，用新的板替换屈曲的板。结果表明，修复后的试件可以在随后的地震中存活并耗散大量的滞回能量，而不会对边界框架造成严重损坏或整体强度下降。研究还发现，该试件具有特殊的冗余度，并表现出稳定的力-位移行为的层间位移的5.2%和5.0%，分别在第一和第二层。从伪动力和循环试验的实验结果进行比较，从一个双条模型，仅使用张力带和单调推覆分析，使用三维有限元模型，分别获得的抗震性能预测，并观察到良好的一致性。
A two-phase experimental program was generated on a full-scale two-story steel plate shear wall with reduced beam section connections and composite floors, to experimentally address the replaceability of infill panels following an earthquake and the seismic behavior of the intermediate beam. In Phase I, the specimen was pseudodynamically tested, subjected to three ground motions of progressively decreasing intensity. The buckled panels were replaced by new panels prior to submitting the specimen to a subsequent pseudodynamic test and cyclic test to failure in Phase II. It is shown that the repaired specimen can survive and dissipate significant amounts of hysteretic energy in a subsequent earthquake without severe damage to the boundary frame or overall strength degradation. It is also found that the specimen had exceptional redundancy and exhibited stable force-displacement behavior up to the story drifts of 5.2 and 5.0% at the first and second story, respectively. Experimental results from pseudodynamic and cyclic tests are compared to seismic performance predictions obtained from a dual strip model using tension only strips and from a monotonic pushover analysis using a three-dimensional finite-element model, respectively, and good agreement is observed.
