| Abstract: | Youxizhou Mingjiang Bridge of Fuzhou is the first open-spandrel rigid-frame arch bridge without vertical columns and oblique supports. The beam-arch joint the key region of open-spandrel rigid-frame arch bridge is complicated in construction and mechanics. The photoelastic test is carried out to obtain the stress gradient and the distribution of local stress in the region, which are important for design and construction of the beam-arch joint of the rigid-frame arch bridge with open spandrel. |
