摘要
为研究粘钢加固后钢筋混凝土梁的受力性能变化,采用ABAQUS有限元程序对钢板加固的矩形截面钢筋混凝土梁和未加固梁进行了非线性有限元数值模拟计算,计算结果表明:钢板加固后的钢筋混凝土梁截面符合平截面假定,且与未加固梁相比,具有更高的极限承载力和刚度。
For the mechanical properties change of reinforced concrete beams of steel reinforcement, using ABAQUS finite element program of reinforced concrete beam with steel reinforcement and reinforcement beam was simulated by nonlinear finite element numerical calculation results show that the steel plate strengthened reinforced concrete beam with the assumption of plane section, and compared with the not reinforced beam,has higher limit bearing capacity and stiffness.
