The Innovative hybrid coupled shear wall system (HCW) is one of the most advanced economical structural systems which has already been conducted. It constitutes of RC shear wall connected to two side steel columns by mean of replaceable coupling steel links. The main design objective of this system is to withstand lateral loads with minimized or even no damage of non-replaceable components (i.e. RC wall and steel columns), while the replaceable coupling steel links could undergo severe damage. This system still highly lacks investigations and detailed estimation as well as being of low efficiency in low-rise buildings. In this research, the emphasis is upon the estimation of the most efficient current HCW systems which have been recommended in literature so far, to be thoroughly calibrated against equivalent conventional RC wall system. Furthermore, new recommendations are presented in intention of optimizing the performance of HCW system to efficiently achieve the design objective through multi-type modifications: links arrangement, internal wall structure and combined systems. The study implements an advanced modelling procedure and extensive nonlinear dynamic analyses with fragility assessment to obtain a highly reliable evaluation. The newly proposed methods reveal excellent efficiency, especially in low-rise buildings.

创新的混合耦合剪力墙系统（HCW）是已经实施的最先进的经济结构系统之一。它由可更换的联结钢连杆连接到两个侧钢柱的RC剪力墙组成。该系统的主要设计目标是承受侧向载荷，将不可更换组件（例如RC壁和钢柱）的损坏降至最低，甚至没有损坏，而可更换的联结钢链节则可能遭受严重损坏。该系统仍然高度缺乏研究和详细的估计，并且在低层建筑中效率低下。在这项研究中，重点是评估迄今为止在文献中推荐的最有效的当前HCW系统，以针对等效的常规RC墙系统进行全面校准。此外，提出了新的建议，旨在优化HCW系统的性能，以通过多种类型的修改有效地实现设计目标：连杆布置，内墙结构和组合系统。该研究实施了先进的建模程序和具有脆弱性评估的广泛非线性动力学分析，以获得高度可靠的评估。新提出的方法显示出优异的效率，尤其是在低层建筑中。该研究实施了先进的建模程序和具有脆弱性评估的广泛非线性动力学分析，以获得高度可靠的评估。新提出的方法显示出优异的效率，尤其是在低层建筑中。该研究实施了先进的建模程序和具有脆弱性评估的广泛非线性动力学分析，以获得高度可靠的评估。新提出的方法显示出优异的效率，尤其是在低层建筑中。
