Inclined hangers behave better than vertical ones under lateral loads (i.e., wind or earthquake) despite they are prone to fatigue phenomenon. In some instances, the slackness problem is seen in some inclined hangers, while others may become overstressed. By considering the modified hanger system, the disadvantages of vertical and inclined systems are resolved, while keeping their advantages. The objective of this study is to propose formulations for the optimum application of novel arrangement of hangers in a cable-arch bridge to suppress problems such as overstressing, force fluctuation, and decreasing the probability of fatigue phenomenon in hangers. To define optimum parameters, the modified hanger system was analyzed and compared with vertical and inclined ones considering nonlinear static analysis under dead load as an initial state plus seismic excitation and dynamic impact load of vehicles. Results indicate that the modified hanger system is improved remarkably in comparison with the inclined and vertical hanger systems.

尽管在横向载荷（例如风或地震）下，倾斜的衣架容易出现疲劳现象，但其性能要优于垂直的衣架。在某些情况下，在某些倾斜的衣架中会发现松弛问题，而另一些衣架可能会承受过大的压力。通过考虑改进的衣架系统，解决了垂直和倾斜系统的缺点，同时保持了它们的优点。这项研究的目的是提出一种最佳应用方案，以最佳地应用新型布置的吊索拱桥，以抑制诸如过应力，力波动和降低吊索疲劳现象等问题。要定义最佳参数，分析了改进的吊架系统，并以静载为初始状态，加上车辆的地震激励和动态冲击载荷下的非线性静态分析，将其与垂直和倾斜的吊架系统进行了比较。结果表明，与倾斜和垂直悬挂系统相比，改进的悬挂系统得到了显着改进。
