NONLINEAR SEISMIC RESPONSES OF A TWO-STRUCTURE-SYSTEM CONNECTED WITH HIGH EFFICIENT DAMPERS

本文对两结构高效阻尼控制体系的地震反应进行了仿真计算和控制参数分析。结果表明,控制参数对结构的地震响应有很大影响,通过合理设计,高效阻尼控制装置能充分利用体系中子结构之间的相互作用,高效地发挥履历型阻尼装置的耗能能力,取得明显的减震控制效果。

The nonlinear seismic responses to two adjacent buildings connected with dampers are studied in the paper. It is called as High Efficient Damper Suitable for Multi-Structure System (HEDMS). A bilinear model for the restoring force of a mild metal damper is used in the study. The HEDMS with two SDOF and the other with two MDOF are simulated analyzed. The results are shown that the parameters of HEDMS have significant effect on the dynamic response of the buildings. Through a reasonable design, the relative displacement of adjacent buildings can be utilized for HEDMS to drive the damper efficiently. It is confirmed that the seismic response of the buildings can be reduced.
