Abstract

Alteration in earthquake input energy correspond with changes in characteristics of the various existing structures, particularly in hysteretic states, has not been examined to such extent that creates enough confidence to present diverse regulations or standards in field of earthquake energy in codes or guidelines. In this paper, at first, based on a somewhat new insight into the concept of earthquake input energy, two concepts of ‘Received Energy’ (ERec) and ‘Returned Energy’ (ERet) have been discussed. Consequently, by applying various hysteretic models for expressing the behavior of structures, including elasto-plastic, bilinear, Wen, Clough, and Takeda models, and two strength levels for the structure, variations of the ‘Total Input Energy’ (ETot) and also (ERec) and (ERet) with respect to the structural specifications have been inspected, by a series of Non-Linear Time History Analyses (NLTHA). Results reveal that when the structural hysteresis specifications, especially its resistance change the values of seismic input energy vary, remarkably. On this basis, structural hysteresis specifications are introduced as measures for limiting the values of damage in various structural systems.
