低屈服点钢构件及结构抗震性能研究进展
Research progress of seismic performance of low yield point steel members and structures
摘要
Abstract
Low yield point(LYP)steel,as an energy dissipation and seismic-resistant material,offers low yield strength,high plastic deformation capacity,and a pronounced strain hardening phase after yielding,which effectively enhances the ductility and energy dissipation performance of structures.As a result,its application in seismic energy dissipation systems has become increasingly widespread.Taking LYP100 and conventional Q345 steel as examples,this paper provides a comparative analysis of the advantages of LYP steel in terms of hysteretic behavior,fatigue resistance and weldability.Furthermore,it reviews and summarizes the seismic performance of LYP steel across four key application areas:steel plate shear walls,energy dissipation dampers,buckling-restrained braces,and joint connectors.Finally,the paper offers perspectives on future research directions,highlighting the need to explore fire resistance,recyclability and the development of design methods and corresponding codes for applying LYP steel at the full structural system level,thereby promoting its broader adoption in engineering practice.关键词
