摘要
斜拉索索梁锚固区域结构复杂,受力集中,是设计的关键。掌握锚固区域在斜拉索作用下的应力大小及分布是十分重要的。采用非线性接触方法,对闵浦二桥索梁锚固区进行有限元计算分析,并对模型进行验证,计算分析锚固区域的应力分布和传力途径,为实际桥梁的设计和施工提供可靠的依据并提供合理的建议。
The cable - girder anchorage zone of stay cable is the key to control design due to structure complex and force concentration, to master the stress value and its distribution in anchorage zone is important. Based on nonlinear contact method, the FE model of the cable-girder anchorage zone for Minpu Bridge Ⅱ is erected and verified, its stress distribution and force transmission path are analysed, which can provide evidence and advise for design and construction of actual bridge.
