基于弹性大挠度理论的幕墙玻璃设计

Curtain-wall glass design based on elasticity theory of large-deflection plate

根据弹性薄板大挠度理论,建立控制方程和边界条件,采用5次B样条函数,运用加权残值法分析计算幕墙玻璃的挠度和应力,并与幕墙玻璃规范设计进行比较.结果表明,采用加权残值法进行幕墙玻璃设计计算是可行的.

On the basis of the large-deflection theory of elastic thin plate, the control equations and boundary conditions are established for curtain-wall glass, The stress and deflection of the curtain-wall glass are calculated by the method of weighted residuals, in conjunction with five order B-spline function. Compared with standard design, the results suggest that the calculation based on the weighted residuals is feasible.
