蜂窝状钢骨混凝土十字形截面柱承载力实用计算公式探讨

DISCUSSION ON PRACTICAL FORMULAS FOR BEARING CAPACITY OF THE CELLULAR SRC CROSS-SHAPED COLUMNS

为了快速设计蜂窝状钢骨混凝土十字形截面柱,根据强度叠加原理,利用平衡条件推导得到蜂窝状钢骨混凝土十字形柱承载力的实用计算公式,并通过工程实例与有限元计算结果进行对比分析,两者吻合较好,且实用计算结果偏于安全,可供类似工程设计参考。

In order to design the cellular SRC cross-shaped columns quickly, according to superposition principle and the conditions of static equilibrium, practical formulas for bearing capacity of the columns were presented. Through comparison and analysis of the engineering examples by the finite element calculation and formulas, it was found that the results by two methods coincided with each other well. The practical calculation results were more conservative, which can provide reference for similar projects design.
