摘 要: 在对梁的弯曲进行研究时,经常要用到弯矩方程。目前常用的弯矩方程表达式通常是一个分段函数表达式,这给理论研究带来了许多冗繁的工作。通过单位阶跃函数,可以把在集中载荷作用下的分段函数的弯矩方程表达式用一个整体方程表示出来,极大的简化了求弯曲变形的计算工作量,同时还具有一定的理论价值。 The equation of camber is often used when the bend of girder is being studied. Today, a lot of heavy works are produced on theoretic research because the expression of the equation of camber is often a expression of divided function. Under the action of the concentrative loads, the expression of divided function of the equation of camber can be expressed with a monolithic equation by unit-step function, and the calculative workload is very simple when bend distortion is solved. At the same time it has a certain theoretic value.
