INFLUENCE OF COMPOSITE REINFORCEMENT ON THE DELOCALIZATION OF PLASTIC HINGES

Following multiple earthquakes in Algeria, large numbers of reinforced concrete structures have been severely damaged or destroyed, making it necessary to evaluate the actual seismic behavior of existing buildings. Classic linear elastic methods do not accurately represent the actual behavior of the structure, which makes it necessary to use calculation methods that take into account the post-elastic domain of the structure. The Push over method is a procedure that correctly predicts dynamic behavior in the event of a future earthquake. For frame structures, the formation of plastic hinges in the columns results in the transformation of the structure into a mechanism. This explains the need to give the post a higher strength than the beams.
