本文提出了一种简化的方法来模拟复杂的滞回性能的木护套连接使用的基本元素，在商业上可用的有限元分析软件。通过组合这些基本元件，可以消除通常需要大量编程的定制连接元件。这既简化了建模过程，又增加了模型的通用性，因此可以针对不同类型的护套连接进行修改。使用这种方法，典型的钉覆板连接已成功建模并实施到剪力墙模型中。此外，一个创新的粘弹性（VE）护套连接已使用相同的策略建模，并用于VE剪力墙模型。虽然这项研究的重点是木框架剪力墙及其连接，所提出的建模技术可以适用于几乎所有的结构构件的滞回性能。
This paper presents a simplified methodology of modeling the complex hysteretic behaviors of wood sheathing connections using basic elements found in commercially available finite-element analysis software. By combining these basic elements, customized connection elements that often require extensive programming can be eliminated. This both simplifies the modeling process and adds versatility to the model, such that it can be modified for different types of sheathing connections. A typical nailed sheathing connection has successfully been modeled and implemented into a shear wall model using this methodology. In addition, an innovative viscoelastic (VE) sheathing connection has been modeled using the same strategy and was used in a VE shear wall model. Though this study was focused on wood frame shear walls and their connections, the proposed modeling technique may be applied to virtually all structural components with hysteretic behaviors.
