Coupled shear wall is one of the main structural elements in high-rise buildings. In this paper, a nonlinear macromodel is proposed to simulate the behavior of coupled shear walls. This model is composed of a multivertical-element model for wall piers and a combined model for coupling beams. In the model for wall piers, some key characters, such as shifting of neutral axis within the wall section, interaction among flexure, shear, and axial forces, can be taken into account. In the model for coupling beams, the deformation of flexure and shear, and the interface bond–slip action are considered by using different elements. Experiments of coupled shear wall specimens with different sizes of coupling beams are carried out to verify the proposed model. A comparison of the analysis with the test results shows that the model is an efficient one in nonlinear analysis of coupled shear walls.

基础隔震能有效地降低上部结构的地震作用，但不同的隔震体系，隔震效果不同。本文根据叠层橡胶支座和滑板摩擦隔震支座的特点，提出组台基础隔震系统，以中国和日本国的在建隔震房屋为工程背景，进行了组合基础隔震房屋模型和基础固定房屋型模拟地震动振动台试验，并对两种试验结果进行了能量分析，分析结果表明组合基础隔震系统中叠层橡胶支座能自动复位，滑板摩擦隔震支座具有良好的耗能能力，隔震效果明显，组合基础隔震系统是一种简单、经济、有效具有广泛应用价值的基础隔震形式。本文获得的大量振动台试验结果可以为隔震设计和加固中使用这种隔震系统及进一步的理论分析提供重要依据。

A combined energy dissipation system is developed in this paper. In this system lead robber dampers and their parallel connection with oil dampers are used in the braces of a structural frame. A dynanric analysis method of the system, including the modelling of the lead robber damper and the oil damper, is proposed. In the analysis method, the restoring force characteresfics of the lead rubber damper is simulated by the Boue-Wcn hysteretic model, and the behaviour of the oil damper is simulated by a velocity and displacement-related model in which the contributions of the oil damper to the damping force and stiffness of the system are considered. A series of shaking table tests of a three storey steel frame with the combined energy dissipation system are carried out Io evaluate the performance of the system and Io verify the analysis method. The test and analysis show that the performance of the combined energy dissipation system is quite satisfactory and there is a good agreement between the analysis and test results, which indicates that the analysis method proposed in this paper is valid and suoable for the dynamic analysis of the combined energy dissipation system.
