Abstract:

建立ANSYS模型模拟整体式桥台无伸缩缝桥梁,比较半波正弦荷载、均布荷载和集中荷载3种不同的加载方式对荷载横向分布影响线(ILTLD)的影响,对比分析挠度、内力2种不同物理量荷载横向分布系数mc,分析无伸缩缝桥梁mc沿桥跨的变化规律,讨论了无伸缩缝桥梁由于内横梁对桥面系刚度贡献引起的荷载横向分布变化。与传统简支桥梁、无伸缩缝斜交桥对比分析荷载的横向分布,同时,通过试验验证了FEA的准确性、可行性。试验和分析结果发现在无伸缩缝桥梁中,可以采用单位集中荷载下挠度的ILTLD来研究荷载横向分布规律;无伸缩缝桥梁的荷载横向分布较简支梁更加均匀;FEA计算结果和试验模型的测试结果吻合良好,并可以在全桥跨近似取值m=mc。
