本文对定向刨花板木剪力墙的抗侧力进行了一系列的研究，对三种循环试验方案的试验结果进行了比较。当剪力墙经受一系列较长的循环组时，失效模式主要是钉连接件的低周疲劳失效，这在地震条件下很少观察到。交替循环加载协议，大幅度，但短序列允许剪力墙，以避免这种类型的钉失败。在高幅短序循环荷载作用下，剪力墙具有较高的抗侧裂性能，接近单调试验的峰值荷载.关键词：木剪力墙，定向刨花板，超大型板，循环荷载，地震，连接件破坏模式，耗能。
This paper compares the test results obtained from three cyclic test protocols in a series of studies on lateral resistance of wood-based shear walls built with oriented strand board panels. When the shear walls were subjected to a long sequence of cycle groups, the failure mode was dominated by low cycle fatigue failure of nail connectors which was rarely observed under seismic conditions. Alternate cyclic loading protocols with large amplitude but short sequence allowed shear walls to avoid this type of nail failure. The results also indicate that under the high amplitude short sequence cyclic test protocol, a higher racking resistance of the shear wall can be achieved which approaches the peak loads from monotonic tests.Key words: wood shear wall, oriented strand board, oversized panel, cyclic lateral loading, earthquake, connector failure mode, energy dissipation.
