Influencing factors on magnitude of concrete stress during the construction course of rigid frame bridge are introduced, factors' contribution quantity on stress is ascertained through grey correlation analysis, which should be prevented overrun of stresses in order to avoid crack or crush of concrete, Validity of grey correlation analysis is confirmed during stress change trend analyses of one rigid...
To investigate the full-range characteristic on nonlinear aerostatic of long span cable-stayed bridge. taking a cable-stayed bridge under construction for example, the realization process of inner and outer incremental double iteration method to solve the aerostatic stability and the full-range physical characteristics of instability are described in detail. Analysis result shows that the critical...
