Structural Design and Analysis of Flat LOFT Apartment with Large Aspect Ratio

[摘要] This project is the building of LOFT system. Due to the high height and large width of the building, the structural design is been challenged. How to use a reasonable structure system on the premise of ensuring the safety of the structure to make the building and structure perfectly unified is the main goal of this engineering structure design. In this paper, according to the irregularity of the multiple structure, the author determined the corresponding seismic performance targets and analyzed the performance indexes of the structure in small earthquakes, medium earthquakes and rare earthquakes. The whole structure is calculated and analyzed, and the stress of the partial floor is calculated, so as to give the damage degree of each member of the high-rise building, and judge whether it meets the earlier development of the corresponding performance target. For this kind of high-rise building, it is an effective design idea to adopt performance-based seismic design method. According to the importance of components, corresponding seismic design methods and corresponding performance objectives are formulated and verified by appropriate analysis methods.
