通过试验研究了框架内填充薄板钢结构剪力墙的低周反复荷载性能。五个单湾和三层的标本进行了测试。试样的测试参数为板厚度以及柱的强度和密实度。试验结果表明，与传统的钢筋混凝土墙和支撑框架不同，设计合理的钢板墙具有很大的延性和耗能能力以及很高的强度。钢板墙相对较薄的板表现出剪切为主的行为的弯矩框架的作用。另一方面，厚板钢板墙显示弯曲为主的行为的悬臂行动。剪切为主的墙壁表现出更好的延性。为了实现大的延性，边界柱必须抵抗由填充板的张力场作用产生的轴向力和横向力的组合。此外，柱必须具有紧凑的截面以防止其早期局部屈曲。
An experimental study was performed to investigate the cyclic behavior of framed steel walls with thin infill plates. Five specimens with a single bay and three stories were tested. Test parameters for the specimens were the plate thickness and the strength and compactness of the column. The test results showed that unlike conventional reinforced concrete walls and braced frames, well-designed steel plate walls exhibited large ductility and energy dissipation capacity as well as high strength. The steel plate walls with relatively thin plates showed shear-dominated behavior by the moment-frame action. On the other hand, steel plate walls with thick plates showed flexure-dominated behavior by the cantilever action. The shear-dominated walls showed better ductility. To achieve large ductility, the boundary columns must resist the combined axial force and transverse force developed by the tension-field action of the infill plates. Also, the columns must have compact sections to prevent their early local buckling.
