Optimal Aseismic Design of Friction-Braced Steel Frames for High-Rise Buildings

摩擦阻尼支撑钢框架是一种新型抗震结构形式。本文首先建立了摩擦阻尼支撑钢框架的简化分析模型,并基于此提出了一种优化高层摩擦阻尼支撑钢框架抗震设计的实用方法。通过优化设计,可节省材料,进一步提高结构的抗震性能。

A simplified model is first established for the analysis of friction-braced steel frames. And then, a practical method is proposed for the optimal aseismic design of friction-braced steel frames in high-rise buildings. Through optimization, the structural aseismic ability increases with the decrease of structural material consumption.
