Abstract

The neccessity of using dynamic analysis method in structures for which equivalent statistical method is not possible, is growing. Endurance Time method is a relatively new Performance Based Erathquake Engineering method for structural evaluation and design. In this method the structure is subjected to a gradually intensifing Accelerograms and its performance is assessed based on the maximum time duration that it can meet the specified performance objectives. The prosperity of this method is based on selection of proper dynamic input Ground motions. Many buldings and cities are located near an active fault. This active fault can produce ground motions with special characteristic resulting from forward-directivity which we refer them as pulse-like ground motion.this pulse-like ground motions are significantly different than other ground motions. These pulse-type motions can place severe demands on structures in the near-fault region. It has been tried to generate proper acceleration function for near fault zone for Endurance Time method. Afterwards the influence of this acceleration function is investigated in response of structures.
