9625386 Moazzami In most building codes, there are very limited guidelines regarding the proportioning of the shear walls and coupling beams. Consequently, the response of the coupled wall assemblies to dynamic loads has been noted to fall short of acceptable ductile behavior. This project discusses some of the current practices in proportioning and design of coupled wall assemblies, highlights some of the shortcomings of these methods, and proposes a new approach that aims at a more comprehensive design of coupled wall assemblies. In particular the hysteretic response of the coupled wall assemblies will be studied based on a proposed mathematical model. The primary concern of this study is to assess the magnitude of cyclic energy dissipation, and determine the balance that must be achieved between strength, stiffness, and ductility capacity of structural members in order to optimize energy dissipation in the system. The outcome of this investigation is a set of design guidelines for proportioning structural members for optimum energy dissipation and stable hysteretic response.***

9625386 Moazzami在大多数建筑规范中，关于剪力墙和连梁比例的指导方针非常有限。因此，联体墙体组件对动力荷载的响应已被注意到达不到可接受的延性性能。本项目讨论了当前在连体墙体组合的比例和设计方面的一些做法，突出了这些方法的一些缺点，并提出了一种旨在更全面地设计连体墙体组合的新方法。特别是，将基于所提出的数学模型来研究连体墙体组件的滞回反应。这项研究的主要目的是评估循环耗能的大小，并确定结构构件的强度、刚度和延性能力之间必须达到的平衡，以优化系统的能量耗散。这项调查的结果是一套结构构件比例的设计指南，以实现最佳的能量耗散和稳定的滞回反应。
