钢筋混凝土曲线梁结构配筋设计方法研究

Mothod of Design Reinforcement of Concrete Curved Beam Structure

本文介绍了作者近几年来关于钢筋混凝土曲线梁桥结构配筋设计方法的研究成果。文中包括了钢筋混凝土曲线梁在混凝土开裂后，计算结构抗扭刚度的经验公式；混凝土软化效应对结构内力的影响；弯、扭、剪、耦合效应作用下结构的配筋设计方法等。这些研究成果已得到大型室内模型梁静载试验和多座大型立交桥峻工通车的验证。并开发有相应的微机软件提供使用。

The mothod of design reinforcement curved beam which are studied by the author in recent years is presented. The recenended formula to calculate the stiffness of reinforcement curved beam after cooking, the effect on internal force of softened concrete, and ti method to design reinforcement of structure under bendig, torsion, Shear and their coupling are proposed also, All these result are tested by the model experiment,verified by many completed large bridges. The computer program based on the result is developed.
