摘要

摘要: 为了改善巨型框架结构体系的抗震性能,提出一种新型的结构体系-含减振子结构巨型框架结构。设计了一典型钢筋混凝土巨型框架结构,将一子框架转变为减振子结构形成含减振子结构的巨型框架结构,采用有限元软件针对该普通巨型框架结构及其减振结构建立了有限元模型并进行了地震弹性反应对比分析,研究了减振子结构和整体结构频率比以及隔震支座阻尼对减震效果的影响。研究结果表明：减振子结构具有显著的减震效果,对频率比有较好的鲁棒性;随着隔震支座阻尼系数增大减震效果逐渐增大,当其大于0.4后,减震效果增加不明显。这为进一步研究该结构体系的奠定了基础,也为该结构的实际工程应用提供了参考。

Abstract: In order to improve the seismic performance of mega-frame structures, a new type of structural system, i.e. mega-frame structures with a vibration absorption substructure, was put forward. A typical mega frame structure and a mega-frame structure with a vibration absorption substructure were designed. Their elastic earthquake responses were analyzed and both results were compared. The influence of frequency ratio and damping on the damping effect was studied. The results show that the vibration absorption substructure has a significant damping effect which has an excellent robustness against the frequency ratio. The damping effect is increased significantly by increasing the isolation bearing damping coefficient ratios until they are greater than 0.4. This work will be helpful in theoretical research and give some assistance to practical engineering.
