    摘要:

    梁的塑性承载力与其对应的塑性变形能力是一对共生体,不能只谈一个而忽略另一个,确定连续梁的塑性承载力大小较为简单,可用手算,如用静力法或机构法,但确定连续梁的塑性变形大小就不简单了,因塑性变形大小与加载历史有关,即要考虑梁的刚度变化过程,通常要用数值计算。本文用有限元软件ANSYS对连续梁的塑性承载力和其对应的塑性变形能力进行了计算,计算中考虑了一些参数(如加载荷载方式、跨长比)的影响,这些影响是在确定塑性承载力时不能忽视的。

    Abstract:

    The plastic bearing capacity of beam and its corresponding plastic deformation ability are co-existed. It is easy to calculate the bearing capacity of continuous beam, Such as static method or mechanism, But it is difficult to calculate the plastic deformation of continuous beam, Because plastic deformation is related to loading history, it means the rigidity change process should be taken into account, Usually use numerical calculation to calculate it, In this paper, the finite element software ANSYS is adopted to calculate the plastic bearing capacity and corresponding plastic deformation of continuous beam. The effect of parameters should be considered, Such as load conditions and span ration, These effects cannot be ignored in calculating the plastic bearing capacity.
