FINITE ELEMENT ANALYSIS OF STEEL MEMBERS UNDER CYCLIC LOADING

The present research work aims at simulating the hysteresis behavior of steel members under the action of earthquake and wind. An algorithm is developed in which a degenerated shall element is used to study the steel members under cyclic loads based on the Updated Lagrange Method. By comparing the numerical results with other available solutions, it is found that the present algorithm offers accurate results and can be used to study the hysteresis behavior of steel plates and shells and even their composites under cyclic loads.
