A Practical Approach for Estimating Elastoplastic Displacements of Multistory and Tall Steel Buildings Under Severe Earthquakes

Based on structures with a typical configuration but different stories as well as 80 suitable seismic records, the statistical amplifying factors for estimating the elastoplastic displacements of braced and unbraced steel building frames subjected to severe earthquakes have been obtained through a great number of numerical calculations. A table of factors with reasonable reliability is proposed for elastoplastic displacement check to implement aseismic design of multistory and tall steel building in practice.
