Optimal design of dynamically loaded reinforced concrete frames under single displacement constraint
Paper deals with reinforced concrete beams and frames subjected to short-time high intensity dynamic pressure. The shape and geometry of the structure and the layout of the longitudinal reinforcement are given and the areas of reinforcement are design variables. The determination of the plastic displacements caused by the pressure is based on the plastic hinge theory and on the assumption that during the dynamic response the structure undergoes stationary displacements. In the analysis several yield mechanisms can be taken into consideration. The problem is to minimize the total amount of reinforcement such that the plastic displacement at a given point of the structure does not exceed the allowable displacement. The variational formulation of the problem is presented and the solution is based on the optimality criteria method which requires an iterative procedure.
