In order to explore the rational suspender layout of reticulated suspender steel box tied arch bridge, eight different suspender layout schemes were established by using finite element software Midas civil, taking a real bridge as the background and the constant inclination angle of suspender as the research variable. The structural stress characteristics of vertical suspender and reticulated suspender layout were analyzed and compared. The results show that the bending moment of arch rib and tied beam of reticulated suspender system is smaller, and the stress of arch beam is closer to the ideal state of “arch rib is compressed, tied beam is pulled”. The results show that in the range of 60 ~90, the smaller the inclination angle is, the more favorable the stress of the structure is, but the lower the moment reduction efficiency is when the inclination angle of the suspender is less than 60.
