摘要

摘要本文详细介绍了在“Benchmark des poutres de la Rance”框架下进行的数值模拟。提出了一种二维模型,其中表示梁的各种本构元素:对于混凝土,使用各向同性损伤模型;对于预应力钢和被动钢,采用弹塑性应变硬化模型。腐蚀效应是通过降低钢的截面和延性来考虑的。光滑钢与混凝土之间的粘结用节理单元来模拟。对单调荷载和循环荷载的各种假设进行了承载能力的估计:健全钢、无延性截面的缩减、有延性截面的缩减。最后将数值计算结果与实验数据库进行了比较。

Modélisations bidimensionnelles
ABSTRACT Numerical simulations performed in the frame of the “Benchmark des poutres de la Rance” are detailed in this paper. A 2D model is proposed in which the various constitutive elements of beams are represented: for concrete, an isotropic damage model is used; for prestressing and passive steels, an elastoplastic strain hardening model is adopted. Corrosion effect is considered by reductions of steel cross-section and ductility. The bond between smooth steel and concrete is modeled with joint elements. The load carrying capacity is estimated for various hypotheses for monotonic and cyclic load: sound steels, reduction of sections without ductility, reduction of sections and ductility. The numerical results are finally compared to experimental database.
