摘要
鉴于定值计算方法的机械性和有限元法的复杂性,依据力学原理,利用积分手段,提出了圆球型网壳结构拱圈荷载传递的简化连续分析方法,总结出了圆球型网壳结构拱圈支承力衰减的基本规律,为网壳结构的优化合理设计提供了一个有效的理论依据。
Usually, the qualitative calculation methods were mechanically. And, the Finite Element Method is complicated. According to the principle of mechanics and the integral calculus, a simplification continuous analytical method of load transmission on arch of the spherical retic- ulated shell structure has been put forward. The basic regularity of arch supporting force attenuation of the spherical reticulated shell structure has been discovered. It provided an effective basis for optimization design of reticulated shell structure in theory.
