Abstract:

Tension structures，different from traditional rigid structures such as steel and concrete,are flexible tensionsystems,whose design and calculation process usually includes form-finding analysis,loading analysis and cuttingpattern generation analysis.In the form-finding process of traditional tension structures supported by elasticbars.such as the cable.web structure and the cable.membrane structure,the interaction between the structure andthe elastic supports is usually neglected.In the present study,basic form -finding form ulae of dynamic relaxation method f0r the form .finding analysis of tension structures are deduced based on the form -finding theory proposed by Michael R.Barnes.Furtherm ore.considering the interaction of elastic supports and tension structures,a formfinding method for tension structures with elastic supports is developed.An example is finally presented to verify the reliability and applicab ility of the proposed method.

Key words: tension structure, integer form-finding, dynamic relaxation, elastic support, kinetic damping
