木框架剪力墙的地震反应往往是由板栓钉连接的滞后特性。通常，对剪力墙和/或连接件进行反向循环测试，以开发和拟合基于经验的滞后模型。因此，生成的模型取决于加载协议。基于机制的模型具有独立于反向循环协议的优点。然而，这些模型需要大量的计算时间，因此，使用这种模型来生成木框架剪力墙的动力响应的计算效率是抗震可靠度分析的瓶颈。
The seismic response of wood frame shear walls is often governed by the hysteresis characteristics of the panel to stud connections. Typically reversed-cyclic tests are performed on shear walls and/or connections to allow the development and fitting of empirical based hysteresis models. The resulting models are therefore loading protocol dependent. Mechanics-based models have the advantage of being independent of the reversed-cyclic protocols. However these models need significant computational time; therefore, the computational efficiency of using such models to generate dynamic response of wood frame shear walls is a bottleneck for seismic reliability analysis.
