高层建筑结构抗震设计方法及结构体系创新

Seismic design method and structural system innovation for high-rise building structures

在推广应用高强材料和新型装配式结构的过程中,经常面临材料强度与延性难以统一协调的问题。本文从复杂高层建筑结构的抗震设计出发,提出了预设屈服模式的性能化设计方法,可以统一考虑结构构件的强度与延性。在此抗震设计方法的基础上,提出了高强高性能混凝土高层建筑结构体系,提出了高性能装配式高层建筑结构体系,可充分发挥高强材料的强度和耗能构件的延性,具有更好的抗震性能。在当前我国高层建筑持续快速发展的环境下,研究成果具有广阔的应用前景。

In promoted application process of high-strength materials and new type assembled structure,strength of material and ductility of structure are difficult to coordinate. Considering the seismic design demand for complicated high-rise building structure,a seismic performance-based design method of predetermined yield mode is proposed,which can consider the strength and ductility demands for structural member as a whole. Based on the proposed design method,high-strength and high-performance concrete high-rise building structure system is put forward,and high-performance assembled structure system is presented also,which can give full play to the strength of material and ductility of energy dissipation member,and have better seismic performance. In current climate of high-rise building developing quickly and continuously,the research results will be widely used in the future.
