摘要
探讨了玻璃幕墙结构中幕墙玻璃在纵力和侧力的共同作用下 ,大位移的力学分析问题 .采用加权残值法的概念 ,用五次 B样条作为未知函数的试函数 ,使其直接满足边界条件 .这种方法与传统的有限元法相比 ,具有未知量少 ,自由度少 ,连续性强 ,边界条件容易满足等优点 .
The mechanical analysis for large displacement under the common effect of vertical and side forces on curtain walls in the structures of glass curtains is discussed. Using the concept of the method of weighted residuals and choosing the fifth B spline as a trial function to meet the needs of boundary conditions. This method, compared with the traditional method of finite element, has the advantage of few unknown quantities, few degrees of freedom and high continuity and is easy to satisfy boundary conditions as well.
