The Calculation of Ultimate Strength for Axial-Loaded Circular Concrete-Filled Steel Tube Stub Columns
摘要:
本文分析了圆形钢管混凝土轴压短柱的受力机理,并借鉴典型约束混凝土的本构关系建立了该类构件极限承载力的计算公式。然后,用建议公式对57个试件进行承载力计算,计算结果与试验结果和规范计算结果吻合良好。
Abstract:
In this paper, the bearing mechanism of axial-loaded circular concrete-filled steel tube stub col-umns is analyzed, and the equations are proposed to evaluate the ultimate strength of the elements based on the typical constitutive model of confined concrete. Then, 57 specimens are calculated with the proposed equations and the calculated results are agreed well with the experimental and normative ones.
