摘要:
预应力型钢混凝土梁是在普通型钢混凝土梁基础上采用预应力技术的一种新型组合结构,它综合了预应力混凝土结构和型钢混凝土结构的优点。采用非线性有限元模型对预应力型钢混凝土梁受力过程进行分析,通过数值模拟与试验结果的对比,验证该模型的可行性。试验研究和有限元分析结果表明:预应力型钢混凝土梁中预应力技术的采用改善了梁的正常工作性能(如挠度和挠度),更有利于材料强度的充分发挥,提高了正截面承载力。
Abstract:
Prestressed steel reinforced concrete beam is a new type of prestressed composite beam which employs prestressing technology in steel reinforced concrete beam and the work combines some properties of SRC beam with prestressing technique. The complete failure procedure of PSRCB is analyzed by three-dimensional nonlinear finite element method. The comparison between the numerical results and experimental results indicate that the analysis approach is valid. The research shows that the presressing technique improves PSRCB’s serviceable performance and ultimate bearing capacity in comparison with SRCB.
