摘要

根据规范和标准执行钢筋混凝土截面的使用要求，需要了解截面内钢筋的应变和应力。对于一般轴向弯曲和双轴弯曲，截面响应平衡平面的求解是一个必须用数值方法解决的问题。本文提出了一种基于外轴向载荷的弯矩曲率族图的一般方法，并提出了一个实验评价。该方法在外载荷、横截面形状和材料本构模型等方面具有通用性。

Flexión compuesta esviada en secciones de hormigón armado. Aproximación numérica

Perform serviceability requirements in reinforced concrete sections according to codes and standards need the knowledge of strain and stress in steel bars within the section. For general axial and biaxial bending, obtaining the response equilibrium plane of the transversal section is a problem that has to be solved by means of a numerical method. This paper exposes a general approach for this purpose, based on moment curvature families of diagrams for the external axial load, and presents an experimental evaluation. The method is universal in terms of to external loads, shape of the transversal sections, and also constitutive models of materials involved.
