[提要] 对利用外粘钢板加固的钢管柱承载力进行试验研究，测定了不同加固方法对其承载力的影响。试验和理论结果均表明，由于外粘钢板与薄壁钢管的联合工作，增大了其厚度，从而提高了钢管的刚度和极限承载力。研究成果可为工程应用提供参考。

The influence on the bearing capacity of steel pipe column reinforced by different method with sticking steel plate is investigated by test.The experimental and theoretical results show that the stiffness and ultimate bearing capacity of the steel pipe column could be raised due to the combined work between the external sticking steel plate and the thinwall steel tube.The results can be reference for the engineering application.
Keywords: thin-wall steel pipe; reinforced; sticking steel plate; bearing capacity; experimental research
