Story Based Ductility Models for Displacement Based Design of Steel Frames
Abstract Estimation of ductility demand distribution through the height of the structure is a very hard task for seismic design engineers working on performance based design of buildings. In this paper a modified direct displacement based design procedure has been proposed. In this method the design force distribution among the height of the structure is obtained based on various ductility demand distributions derived from modal characteristics of the structure and mathematical formulations. The method has been applied to the moment steel frames in low, medium and high rise buildings and the results of various ductility distributions have been compared. The plastic mechanism has also been modeled and the efficiencies and deficiencies of each have been discussed through various numerical examples. The effect of yield mechanisms and ductility demand patterns for various building types on the equivalent SDOF parameters have been investigated compared to the time history analysis results to find the sensitive parameters.
