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 mechan ica l behavior of steel reinforced concrete beams, e ight steel re inforced concrete beams which containH stee l are tested. The test resu lts show: ( 1) The craze moment of stee l re inforced concrete beam is independent of bond force, st irrups and shear connectors. ( 2)The steel reinforced concrete beam has better ductility and shear fa ilure occurs w hen stirrups are less. ( 3) The bond fo rce has an obv ious effect on load-carrying capacity and rig idity o f stee l reinforced concrete beam. ( 4)The slippage appears at load anaphase and rapid ly increases at ultimate load and is not influenced by shear connectors.
