Abstract

Abstract:

hen applying the general methods for the form-finding of membrane structures,the connecting nodes between the membrane structure and the supporting structure are regarded as fixed nod es.and the dis-placements of the supporting structure at the connecting nodes are not talcen into account. thus resulting in the diference between form -finding results and actual situations To solve this problem, the interaction between the
membrane structure and the supporting structure in the form-finding process is analyzed based on the Force Den-sity Method.Correspo nding software for the form-finding is then programmed. Finally,two examples are pre-sented to verify the feasibility of the proposed method .

Key words: elastic bar, membrane structure, form-finding, interaction
