Open publisher page 5 citations

Abstract

Based on experimental research on the seismic behaviors of two frames,one with specially shaped columns, and the other with wide flange specially shaped columns on the first floor,the failure characteristics,bearing capacity,ductility,hysteresis properties,subsequence of hinge occurence and rigidity degeneracy of the two specimens were compared.The results show that the adoption of wide flange improves the rigidity of the columms on the first floor and correspondingly some other seismic behaviors of frame with normal specially shaped columns to resist the earthquake effectively.
