Seismic Analysis and Research on Steel Structure Adding Layer System used in the High-rise Concrete Buildings
Xing Jie;Campus Planning and Construction Department,Tsinghua University;
Based on the practical engineering,through numerical simulation analysis of research methods,multiple sets of numerical calculation model are established for simulation,qualitative analysis and quantitative calculation method to clarify the necessity of interior layer of aseismic design for steel structure,and the steel frame structure system for tall concrete building interior layer is put forward. According to this research: steel structure indoor add layer only static calculation without considering the design method of seismic action of steel structure of component is not safe indoor add layer; steel structure indoor add layer components internal force with the principal part of the height of the building structure,structure layout,structure form and so on are closely related. Both ends vertical components are directly connected with the main structure and layer structure of the steel beam earthquake-resistant calculation is needed.
