本文通过对薄壁离心钢管混凝土构件的弯距系数和偏心距折减系数表达式的推导,提出了该种构件正截面强度简化计算公式,经计算结果表明,在构件的特征值φ■0.2～2.5、相对偏心距ε≤5的范围内,最大误差不超过5％,已能满足工程设计的精度要求。可供设计参考。 In this paper, by deducing the expressions of the flexural distance coefficient and the eccentricity reduction coefficient of the thin-wall centrifugal steel tube concrete member, a simplified calculation formula for the normal section strength of the member is proposed. The calculated results show that the characteristic value of the member is φ■0.2～ 2.5, within the range of relative eccentricity ε ≤ 5, the maximum error does not exceed 5%, has been able to meet the accuracy requirements of engineering design. For design reference.
