本文结合工程实例,利用盈建科(YJK)软件对同一框架结构模型,进行了楼梯参与整体计算与不参与整体计算的比较,得出结论:框架结构楼梯参与结构的整体计算对结构刚度及扭转影响很大(对顺楼梯方向影响较大,对垂直于楼梯方向影响相对较小),对周期影响相对较小,证明了传统结构设计的不足,并提出了更为合理优化的结构设计方案。
In this paper, with the engineering example, using the YJK software to compare the whole staircase participation calculation and non-participation overall calculation with the same frame structure model, the conclusion is drawn that the integral calculation of participation structure of the staircase structure has a significant effect on the structural rigidity and torsion Which has a great impact on the direction of the stairs and relatively less influence on the direction perpendicular to the stairs. The impact on the cycle is relatively small, which proves the deficiencies of the traditional structural design and presents a more rational and optimized structural design scheme.
