Performance Levels of RC Structures by Non-Linear Pushover Analysis
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 4
Abstract
In the recent earthquakes in which many concrete structures have been severely damaged or collapsed, have indicated the need for evaluating the seismic adequacy of existing buildings. About 60% of the land area of our country is susceptible to damaging levels of seismic hazard. We can’t avoid future earthquakes, but preparedness and safe building construction practices can certainly reduce the extent of damage and loss. In order to strengthen and resist the buildings for future earthquakes, the behavior of a building during earthquakes depends critically on its overall shape, size and geometry. The nonlinear pushover analysis is becoming a popular tool for seismic performance evaluation of existing and new structures. The weak zones in the structure can be examined by conducting this push over analysis and then it will be decided whether the particular part is to be retrofitted or rehabilitated according to the requirement. This method determines the base shear capacity of the building and performance levels of each part of building under varying intensity of seismic force. The results of effects of different plan on seismic response of buildings have been presented in terms of displacement, base shear and plastic hinge pattern
