| 摘 要： | 为了研究型钢混凝土梁的受力性能，对8根内含H型钢的型钢混凝土梁进行了试验和研究，结果表明：型钢混凝土梁的开裂弯矩与粘结力、箍筋、剪力连接件无关；型钢混凝土梁具有较好的延性；当配箍较少时，型钢混凝土梁会发生斜截面受剪破坏；粘结力对梁的承载力和刚度有显著影响；型钢和混凝土之间的滑移一般在加载后期出现，在接近极限荷载时迅速增加，剪力连接件对滑移无影响。

| Abstract: | In order to investigate the mechanical behavior of steel reinforced concrete beams,eight steel reinforced concrete beams which contain H steel are tested.The test results show:(1)The craze moment of steel reinforced concrete beam is independent of bond force,stirrups and shear connectors.(2)The steel reinforced concrete beam has better ductility and shear failure occurs when stirrups are less.(3)The bond force has an obvious effect on load-carrying capacity and rigidity of steel reinforced concrete beam.(4)The slippage appears at load anaphase and rapidly increases at ultimate load and is not influenced by shear connectors. |
