Distribution of Drift, Hysteretic Energy and Damage in Reinforced Concrete Buildings with Uniform Strength Ratio

Abstract eng:
Assessment of the behavior of structures during recent earthquakes indicates that much damage has happened to the buildings including those designed according to the engineering principles. The preliminary design of most of buildings is based on equivalent static and spectral dynamic forces specified by the governing seismic codes. The height-wise distribution of these horizontal forces seems to be based implicitly on the elastic vibration modes. Studies have shown that most structures subjected to strong ground motions fall into an inelastic state. Thus it is necessary to study the inelastic behavior of structures undergoing such earthquakes. The aim of this study is to investigate the effect of the two above-mentioned lateral loading patterns on height-wise distribution of drift, hysteretic energy and damage subjected to severe earthquakes by considering four reinforced concrete buildings. The results indicate that in strong ground motions, none of the lateral loading patterns will lead to uniform distribution of drift, hysteretic energy and damage, and an intense concentration of the values of these parameters can be observed in one or two stories especially in equivalent static method. This will consequently hinder the serviceability of the maximum capacity of structures.
