摘　　要：本文进行了4根二次成型的钢一混凝土组合梁的试验,构件之间的主要区别为连接方式和剪力连接程度的差异,着重分析这种新型组合梁的破坏形态、荷载-挠度曲线、荷载-应变曲线和沿截面高度方向的应变分布等。通过试验研究初步了解了这种新型组合梁的受力特点,为此类构件在结构加固工程中的应用提供了理论依据。The behaviors of four anchor connection steel-concrete composite beams are experimented in this essay. The main differences between the components lie in the connecting methods and the extent of shearing force. The failure modes, load-deflection curves, load-strain curves, load-slip curves and the distribution of strain along the cross section are emphaticly analyzed. The conclusion of the behaviors of these composite beams which are well studies by the static test can provide an efficient theory for reinforcement engineering.
