| By making use of subdomain weighted residuals method, the internal forces of curved multi-girder bridge is analysed in this paper. It widens the applicable region for the general method of weighted residuals. For curved multi-girder bridge simulated as an orthotropic sector plate, this methodcan solve the influence fields of internal forces, and give a different way for the analysis of curved multi-girder bridge designed with the method of influence fields. Finally, a numerical example is presented. |
