【Abstract】 A survey of the development about the floor response spectrum is presented in this paper.Dynamic properties of primary-secondary systems,such as interaction between primary and secondary structures,tuning,non-classical damping,and multiple-supported,are given in details,and the methods of traditional and modified floor response spectra as well as floor response spectrum in the multiple earthquake are described.Some problems further to explore are proposed with engineering significance.更多还原
