ON TOPOLOGY OPTIMIZATION OF TRUSSES WITH MULTIPLE LOADING CONDITIONS AND BE-HAVIOUR CONSTRAINTS

A topology optimization method for truss structures is described in this paper. In this method, the member forces are considered as design variables and the structural weight as objective function. Three main advantages, compared with the prevailing methods, existed in the method. Firstly, the introduction of new design variables makes that not only the main difficulty of pregiven displacement field is warded off but it is more easily for the constraints such as stress and displacement to be dealt with duri...
