In this paper, a static collapse analysis method for cyclic multipoint-loaded structures using the displacement control is proposed. Then, It is confirmed that this method can be applied to the post peak analysis and the cyclic loading analyses by an example problem.
In this method, “loading element” is proposed. This element calculates inner forces so that given load ratio conditions are always fulfilled. For application to the existing analysis program, we only have to add this proposed loading element. So, application of this method is very easy and simple.
