摘要
用能量法推导了刚性铰支大梁上拱和上翘曲线的一般方程。进一步探讨了弹性支座对上拱和上翘曲线的影响，并得出了相应的关系式。最后，通过实例介绍了一般方程的使用方法。同时引进了对弹性支座影响的处理方法。
This paper gives a general equation for the ideal curve of crane beam with joint support,then further discusses the effect of elastic support on the curve, and gives the complement equation. In the end the paper employs examples to prcsent the operation method for the general equation,and introduces the method to cope with the effect of the elastic support.
