摘要
建立了幕墙正交索网结构的计算力学模型,研究单层索网在网点分配荷载及预张力作用下的平衡方程、位移协调和变形体位能驻值方程,构成多变元的非线性耦合方程组。采用有限分析法将非线性耦合方程组解耦,寻求局部解析解再转化为全局数值解,设计小尺度实际模型在多点荷载作用下的内力和变形的实验,最后给出相关算例。
The calculation mechanics model of orthogonal rope net stnucture on the curtain wall is expanded. The point of intersection accepting distributive loads and tensile force after the rope net distortion,the balance equations and displacement equations and the potential energy equations and kinetic energy equations are constituted. Then these non-linear squation groups of the multivariate coupled equation are founded and decoupled. Using the theory of finite analysis method,the analytical solution is searched the numerical solution is calculated. Design of small-scale physical model,the deformation and internal force of the model structure under the multi-point load are study. FinaUy,the example is introduced.
