钢筋砼大直径群仓仓壁的内力计算

本文对一组大直径群仓,考虑到筒仓之间相互约束影响的作用,特别是在星仓装载时,其内力计算应与单仓有所区别。根据空间弹性理论,采用有限元计算方法,分别计算了群仓在不同装载方式下的内力,分析探讨群仓协同工作时的最危险应力区域,并与按单仓设计时内力进行比较,从而对群仓仓壁的强度设计提供了一种计算方法。

CALCULATION OF INTERNAL FORCESFOR RC.BIG DIAMETER GROUPED SILO WALLS

This paper is aiming at the big diameter grouped silos, and considering the restrain and effected action among the group silos, especially, star siloare fully loaded, compared with singe silo, we think that the method of calculating internal force is different. based on the spacial elastic theory adopted the calculated method lf finite element, we have calculated the internal forces for RC. grouped silos with different loading patterns. Analyzed and discussed the most dangerous stress of the co-operate work for group silos, compared with the internal forces which desigened as single silos. So we can provide a method for the strength design of the group silo walls.
