基于连续化理论模型,建立了静风荷载与索网结构面外位移约束及索力共同作用的静力平衡微分方程,结合预应力竖索和横索结构的既有理论分析,采用伽辽金方法分析得出索网幕墙结构考虑玻璃自重与平均风荷载耦合作用下的位移变形解,确定索网幕墙结构的静力作用最大变形位置;通过算例分析研究自重因素对索网幕墙找形的影响。结果表明,索网幕墙结构在平均风荷载作用下变形最大位移随着玻璃自重的增大而增大,而变形最大位移所在位置随自重的增大逐渐下移。
Based on the continuum theory model, the static equilibrium differential equations of static wind load and the influence of out-of-plane displacement of cable net and the interaction of cable forces were established. Based on the existing theoretical analysis of prestressed vertical and horizontal cable structures, Methods The displacement deformation solution considering the self-weight of glass net and the average wind load is obtained by the analysis of the method to determine the maximum deformation position of the static effect of the cable net curtain wall structure. By the example analysis, influences. The results show that the maximum displacement of cable net curtain wall structure increases with the increase of self-weight of glass under mean wind load, and the position of maximum displacement of deformation decreases gradually with the increase of dead weight.
