摘要
根据力法原理,推导出了横向三支座桥梁的支反力计算公式,并研究了桥梁横向整体刚度、支座弹性约束刚度等对支座受力分布的影响,同时建立有限元模型验证了公式的正确性,最后指出该公式计算方法简单易行、精确度高,能较好的满足工程需要。
According to the principle of force method, and studies the bridge transverse integral stiffness, bearing elastic constraint stiffness, im- pact on the distribution of bearing, and also establish element model verified the formula, and points out that： the method is simple in calculation, high accuracy, can meet the requirement of engineering.
