摘要
在文献的基础上探讨了正交正放类网架的静力计算问题。文中采用网架的拟夹层板连续化模型,网架的静力控制方程采用六阶偏微分方程,应用加权残值法中的样条配点法计算网架的挠度和内力。文中给出若干算例,计算效果良好.
This paper investigates the static calculatioin for orthogonal and ortho-laid space truss on docu ment [1]. In the paper,the space truss is assumed as the sandwich plate. The static control equation is the sixth order differential equation. The collocation method in MWR is suggested to solve the defelectons of joints and the internal forces of projects for the space truss. Numerial static examples have been given,the results are satisfied.
