Evaluation the efficiency of seismic resistance reinforced concrete buildings depending on Pushover Method, Tabiyat suburb residential buildings in Latakia model


Abstract in English

Pushover method or method of nonlinear static analysis is considered the latest and best way to study and evaluate the buildings under effect of seismic load. The method is based on the study of deformation occurring in the building, formation of plastic hinge in elements, in addition to the redistribution of internal forces in building elements under the effect of earthquake loads. Pushover method was applied to evaluate the Model of residential buildings in Latakia suburb Tabiyat, who has designed and implemented before the issuance of the code which earthquake load considered. First, the dynamic characteristics of the building (Period, and Mode shape) were identified in the cases of modeling 2D (plane) and 3D (spatial). Second, an analysis of the building under earthquake load by Pushover method depending on ETABS Program was conducted. We have got seven side cases push of the building, and have identified the location of plastic hinge in the building elements, and draw a curved capacity for the building, which represents the relationship between base shear force and lateral deflection at the top of the building. It was concluded that the building is a good resistance to the effect of earthquake. It was concluded with backing the adoption of Pushover method to evaluate existing buildings, and study the dynamic behavior, and the extent of resistance to the effect of earthquake.
