composite rc beam

基本解释

The evaluation method of bearing capacity of RC composite beam bridge based on non-linear properties of the RC composite beam bridge is presented in this paper.
本文在掌握了钢筋混凝土组合梁桥的非线性性能的基础上，研究制订了该类桥梁承载能力的评定方法，可供实践试用。
The non-classical theory is used to deduce the stiffness of FRP-RC composite beam, and with the help of CELL BEAM23 in software ANSYS the mode calculating method is brought forth too.
具体是采用非经典理论推导出FRP -RC复合梁的抗弯、抗剪刚度，然后提出结合ANSYS软件的FRP -RC结构有限元模态分析方法。
Results show that ultimate bearing capacity of RC beam strengthened by composite CFRP sheets is much higher than that of direct pasting CFRP. Cracking load and ductility are improved higher too.
结果表明：与直接粘贴CFRP布相比，采用剔槽植入钢筋置换混凝土灌胶再粘贴CFRP布复合加固方案加固的梁极限承载力有显著提高，开裂荷载及延性有较大提高；
