| Abstract: | Based on the overall incremental launching construction of beam-arch composite arch bridge of Jiubao bridge in Hangzhou,the finite element software MIDAS/Civil was adopted to simulate the overall incremental launching construction,and the stresses of the measuring points on the critical sections of the main longitudinal beam,the main and side arches,the launching nose and the temporary pole were measured and analyzed.The results show that(1) during the process of incremental launching,actual stresses of mea... |
