摘要
根据影响线定理,本文将求解连续梁影响线的问题转化为求解特殊荷载作用下的位移问题,并推导出特殊荷载的等效节点力的公式。用有限元法计算影响线,获得了令人满意的计算结果。
beams are transfered into the problems of solving its displacements under a special load and the formula of the equivalent nodal forces of the elements subjected to the special load are derived in the article.By means of finite element method the influence lines are satisfactorily calculated
