摘　　要：为了研究钢-混凝土蜂窝组合梁这一新型构件的静载受力性能,设计了3根钢-混凝土蜂窝组合梁和1根实腹型钢-混凝土组合梁进行静载试验,设计试件时考虑了蜂窝型钢不同扩张比的影响因素。研究结果表明,钢-混凝土蜂窝组合梁在静力荷载作用下截面应变符合平截面假定;钢-混凝土蜂窝组合梁具有较好的受力性能;钢-混凝土蜂窝组合梁与钢梁扩张前的实腹型钢-混凝土组合梁比较,抗弯刚度及承载力有明显提高,扩张比λ约为1.36时,其极限承载力为最大。In order to study the static mechanical properties of a new steel concrete honeycomb composite beam, three cellular steel-concrete composite beams and one solid web steel-concrete composite beam were designed for research in the static loading test in which honeycomb steels with different expansion ratios are considered. The results show that the cellular concrete composite beam follows the plane section assumption under static loadings; compared with the solid web steel-concrete composite beam, the stiffness and load bearing capacity of the steel-concrete castellated composite beam are higher; and the bearing capacity reaches its maximum potential when the ratio of the expansion reaches about 1.36.
