巨型框架结构又被称为主、次框架结构,其独特的两级受力体系不仅有利于提高结构整体性,改善结构安全性能,减少材料用量和工程造价,亦给建筑设计带来了更大的灵活性,因此在超高层建筑中正得到越来越广泛的应用。本文结合对采用巨型框架结构体系的南京多媒体通讯大楼 1∶ 25微粒混凝土模型的模拟地震振动台试验的分析和探讨,着重研究了巨型框架结构的动力特性、弹性和弹塑性地震反应及结构的破坏形式。
Mega-frame structure, also known as primary and secondary frame structure, its unique two-stage force system is not only conducive to improving the structural integrity, improve structural safety performance, reduce material consumption and project cost, but also to bring greater architectural design Therefore, it is getting more and more widely used in super high-rise buildings. In this paper, based on the analysis and discussion of the simulated seismic shaking table test of the 1: 25 particle concrete model of Nanjing Multimedia Communication Building which adopts the mega frame structure system, the dynamic characteristics, elastic and elastoplastic seismic response and structural damage of the mega frame structure are mainly studied form.
