Distribution of Earthquake Input Energy in Structures
1. INTRODUCTION
The current seismic design practice which is based on strength principles (using the acceleration spectra) does not directly account for the influence of the duration of strong motion nor for the hysteretic behavior of the structure. The hysteretic behavior is addressed indirectly by using the response modification factor R which is based primarily on the structural system selected. A design approach based on energy (Vision 2000), on the other hand, has the potential to address the effects of the duration and hysteretic behavior directly.
