摘要
针对简支叠梁的受力特点,建立简支叠梁的简化分析模型,对简支叠梁之间的接触力分布提出假设,运用变形协调条件推导出接触力函数,并对接触力函数的有效性进行了讨论。工程实例应用表明所提方法的合理性,为求解简支叠梁的内力和变形提供了简便的计算方法。
A simple analytical model for simply supported laminated beams is established based on the characteristic of beams under stress. With the assumption of contact force distribution between beams composing a simply supported laminated beam, a contact force function is deduced by applying deformation compatibility condition, and its validity is discussed. The engineering application indicates that the method presented is valid and can serve as a simple and convenient method for calculating the internal force and deformation of simply supported laminated beams.
