摘要

为了研究钢筋混凝土（RC）柱的横向抗力特性

基于RC梁面力效应的全量应变理论进行改进

考虑了柱轴向荷载和端部约束作用。通过RC柱截面应力和弯矩关系

并基于轴力平衡

建立了轴向荷载与截面中性轴的关系方程;继而基于轴向荷载中性轴关系方程、变形协调关系和虚功原理

建立了横向均布荷载作用下RC柱的抗力方程。对方程进行解析求解

最终建立了计算RC柱横向抗力特性的非线性理论方法

并得到了RC柱横向抗力和位移关系的解析表达式。将该理论方法的计算结果与有限元计算结果进行分析比较的结果表明

本文所建立的方法能够正确反映轴向和横向荷载联合作用下RC柱的横向变形与抗力的关系。该理论模型的建立可为进一步的RC柱抗爆动力分析奠定基础。

Abstract

In order to analyze the properties of horizontal resistance of RC columns

the total strain membrane effect theory of the RC beam was improved to found a theoretical method.The equation on the axial load and sectional neutral axis was found through the cross-sectional relationship and equilibrium relationship.The horizontal resistance equation was presented on the basis of virtual work principle

geometric relationship and equation on axial load and sectional neutral axis

which takes the axial gravity load and boundary restraint of RC column into account.A new theory and analytic formula was derived to calculate the relationship between horizontal resistance and deformation of RC column.The theoretical results were compared with the FEM analysis.The results revealed that the approach could calculate the horizontal resistance-deformation relationship of RC columns quantitatively

which was validated by the good agreement with the numerical results.The proposed theory has laid a foundation for further anti-blast dynamic analysis of RC columns subjected to blast loads.
