本文结合具体的工程实例,通过多方案比较分析、数值模拟仿真分析等研究方法介绍了高层混凝土建筑室内加层的两种结构形式:钢框架室内加层结构和混凝土框架室内加层结构,通过对比基本周期、地震剪力、层间位移角等技术指标,定性分析和定量计算的方法阐明两种加层结构体系的优缺点,提出适用于高层混凝土建筑室内加层的钢框架结构体系。根据本文研究可知:室内加层对主体结构无不利影响,主体建筑的整体刚度、基本自振周期等技术指标基本不受室内加层设置的影响,主体建筑抗震设计只需考虑加层设置前后的恒、活荷载变化的影响。
Based on the concrete engineering examples, this paper introduces two kinds of structural forms of indoor adding layer in high-rise concrete buildings through multi-scheme comparative analysis, numerical simulation and other research methods: steel frame indoor plus layer structure and concrete frame indoor plus layer structure. Basic cycle, seismic shear force and displacement angle between layers and other technical indicators, qualitative analysis and quantitative calculation method to illustrate the advantages and disadvantages of two kinds of additional layer system, and put forward the steel frame structure system which is suitable for indoor layering of high-rise concrete building. According to the research of this paper, it can be known that indoor plus layer has no adverse effect on the structure of the main structure, the overall stiffness of the main building and the basic natural vibration period and other technical indicators are basically unaffected by the indoor plus layer setting, seismic design of the main building only needs to consider Constant, live load changes.
