点式玻璃建筑中柔性支承体系承载性能的非线性分析

GEOMETRIC NON-LINEAR ANALYSIS OF FLEXIBLE SUPPORTING SYSTEMS FOR POINT-SUPPORTING GLASS BUILDING

    摘要
  • 摘要: 柔性支承体系在设计时必须采用可以考虑几何非线性的计算程序进行设计.在推导出可以考虑几何非线性平面二力杆单元和平面梁单元的切线刚度矩阵基础上,编制了计算柔性支承体系的有限元程序,并在其中加入索单元特性和可以考虑初始预应力的影响.使用该程序,可以方便的对柔性支承体系进行设计.还利用这套程序,对两种典型的柔性支承体系进行了计算比较分析.

     

    Abstract: A calculation method for flexible supporting system with large displacements and deformations is developed so as to determine the tangent stiffness and internal stress vector. The formulation is established for a '2D-bar'element and a '2D-beam'element. A program is developed and two typical flexible supporting system models are studied. The results lay down the basis for further research work.
