Earthquake Resistance of Non-Ductile Reinforce Concrete Building

Abstract

This study emphasized to investigate the earthquake force resistance of non-ductile the reinforced concrete building constructed in Thailand. The 4-story RC building was adopted to evaluate the earthquake resistance capacity when it subjected to earthquake forces. A 4-story RC building is assumed to locate in three intensity levels of Thailand’s hazard area, surveillance zone, the first zone, and the second zone. The RC frame was modeled as a two-dimensional. The moment-rotation relationship consists of the yielding moment, capping moment, and capping rotation obtained in the plastic hinge model. The capacity curve indicated that the 4-story RC building remains elastic behavior when the earthquake force regarded as base shear subjected to the building not more than 10653-kilogram forces and it can resist the maximum base shear in an inelastic range around 17140-kilogram forces before the collapse. When the building subjected to the earthquake forces from three intensity levels of Thailand’s hazard area, the beam and column were severely damaged and the global behavior of the building beyond the level of collapse prevention means the building is collapse.
