[提要]  本文为关于一种新型带竖缝剪力墙性能分析的第一部分。这一部分着重介绍了新提出的带缝剪力墙的抗震设计概念，并对该结构的关键部位——缝槽间连梁作了非线性力学分析，文中分析方法得到了试验数据的论证。分析结果可为正确的连梁设计提供理论依据，并为整体结构的分析提供可靠的连梁非线性力学模型，从而为分析带缝剪力墙的整体性能打下基础。

This paper is the first part of a two-part research report, In this part, the design concept of earthquake resistant R.C. slit walls is presented, and an attempt has been made to analysis nonlinear behaviour of connecting beams, which are thought as the key control members of the slit shear walls. The results, which have been verified by experiments, can serve as the basis for correct modelling of connecting beams used for the analysis of the whole slit shear wall structures.
Keywords: slit shear wall; earthquake resistant behaviour; connecting beams; mechanical analysis
