摘　　要：研究等分吊点法在不同加载方式下钢梁荷载挠度曲线的规律,以寻求最合理的加载方式。研究结果表明:采用绳索等分吊点法时,两端向中间对称加载的过程中,钢梁受力最为合理,而均布加载时梁的受力状态最差,但均布加载最接近使用状况,因此在今后校验钢梁性能时应首先选择均布加载方式。This paper studied on steel beam load deflection curves under different loading modes by the method of uniform hanging point, to find the most reasonable way of loading. Results showed that using ropes equal hanging point method, symmetrical in the process of loading, both ends to the middle beam stress was the most reasonable, and the stress of uniform load beam the worst, but uniformly distributed load was the closest to use, so the uniform load performance should be chosen firstly in the future when we check the performance of a steel beam
