Abstract
Reinforced concrete frame box culverts are widely used in underground structures. At big skew an-gles, the normally used 2D simplified computational models for the reinforced concrete frame box culverts are not suitable. Using the finite element software Midas, the frame culvert was modelled by plate elements and beam elements under different conditions. Comparisons were made between the simplified method and the fi-nite element modeling. The result shows that some design parameters, such as skew angle, base coefficient and box width, have great influence on structural internal forces. The effects were analyzed for future project reference.关键词
