LARGE DEFLECTION ANALYSIS OF TENSIONED MEMBRANE STRUCTURES ALLOWING FOR SUPPORT FLEXIBILITY

摘要: Publisher Summary Tensioned membrane structures are normally reinforced with pre-tensioned cables, and supported by metal space frames of lightweight thereafter. Conventional analysis design for tensioned based on two assemblages: fixing the support positions determining equilibrium shape cable-membrane at first, checking adequacy against reactions. Under this methodology, interaction between frame is neglected. An integrated nonlinear finite element (FE) analysis, including cable element, beam in FE library, proposed chapter large deflection allowing flexibility. The structure examined through numerical study a saddle shade pavilion structure. Results were noted to deviate considerably from those obtained an isolated which reveals that necessary structural engineers determine whether or not effects elastic deformations supports should be taken into account structures. This presents flexible supports, examines cables practical Numerical results demonstrate flexibility account.
