摘要：	In urban areas, construction of an underpass, below railway tracks using a system of pushing a precast reinforced concrete box structure with jacks is an ideal solution over Road Over Bridge (ROB). Construction details often calls for skew box underpasses. These skew boxes are typically analysed as two dimensional frames. Three dimensional finite element analysis represents the actual behaviour of these type of skew underpass box structure that a two dimensional frame cannot capture. These box structures are pushed in segments rather than as a whole. From the finite element analysis, it has been found that the analysis of the box considering full length is not conservative if the boxes are pushed as segments with skew angle greater than 30°. In this paper an attempt has been made to propose some factors that user can directly convert the results from the given plane frame analysis to similar as Finite Element analysis. SAP2000 is used for the modelling and analysis of box structure. The effect of height on the behaviour of the skew underpass box has been reviewed using both finite element and plane frame analysis. From the analysis it is observed that the frame analysis overestimates the actual moments in the middle box segments for the considered section.
