简支转连续梁桥双支座对梁受力影响分析

Effect Analysis of Double Bearing to Beam of Simply Supported-continuous Bridge

分析了简支梁、连续梁及简支转连续梁桥受力特点和单支座、弹性双支座及刚性双支座简支转连续梁的静力学和动力学特点。利用弹簧单元来模拟双支座简支转连续梁桥的计算,并通过工程实例实测数据与计算结果对比分析,证明弹性双支座模型的可行性。

The paper analyzed the stress characteristics of simply supported beams, continuous beams and the statics and dynamics characteristics of simply supported-continuous bridge of single-bearing, flexible double bearing and rigid double bearing. Using spring elements to simulate the double-bearing simply-supported continuous beam bridge, through the comparative analysis of specific project examples measured data and the simulated data, the paper proves the feasibility of flexible double-bearing model.
