本文指出了以平截面假定为基础的偏心受压构件截面强度计算中存在的问题。针对这些问题,提出了计算对称配筋小偏心受压构件截面强度的三个方案以及R_w、σ_g的计算公式。由此使截面设计和校核方法大为简化,且有较好的计算结果。
This paper points out the problems in the calculation of the section strength of eccentric compression members based on the assumption of flat sections. In order to solve these problems, three schemes to calculate the cross-sectional strength of the symmetrically-recognized small eccentric compression members and the calculation formulae of R_w and σ_g are proposed. This greatly simplifies the cross-section design and verification method and has better calculation results.
