摘要：
With the rapid development of urban viaduct, an increasing number of curved bridges and irregular ramp bridges are constructed. For the analysis of these structures, the conventional plan link method can not obtain satisfactory results and meet with the engineering accuracy requirement. On the contrary, the special grid frame method can solve this issue better. Based on an irregular ramp bridge located in Guangzhou-Shenzhen express way, how to establish FE model by grid frame method in Midas/Civil is firstly introduced in this paper, then how to establish 3D block FE model for the validation of grid frame model is described. Furthermore, the analysis results of the above mentioned grid frame model are presented at the end.
