摘　　要：提出几种不同的腹板开洞连续组合梁的洞口补强方式,通过有限元计算对不同补强方法的连续组合梁的力学性能进行了比较。计算结果表明,组合梁洞口区域采取补强措施后能够在一定程度上提高洞口区域的抗弯和抗剪承载力,增强其刚度和局部稳定性,并得到了比较有效的洞口补强方法可以用于工程实践。Several reinforcing methods are reserched, mechanical properties are compared by FEM calculation in different reinforced continuous composite beam. The result indicates that the bending and vertical shear capacity of continuous composite beam with web opening can be effectively enhanced to a certain extent. In addition, stiffness and local stability at web opening area can be also increased. Effec- tive reinforcing method is presented which can be used in engineering practice.
