Abstract: To study the space creep effect of heavy haul railway continuous rigid frame bridge, constitutive relation of concrete creep was modified by user programmable features (UPFs) of ANSYS software. Based on the largest heavy haul railway in Shanxi province, creep research of bridge was conducted. Box girders were simulated by shell element and piers by spatial beam elements. Considering the construction process of a continuous rigid frame bridge, refined analysis of three dimensional creep effect for heavy haul railway continuous rigid frame bridge was carried out. The results of refined analysis model and beam model were compared. Difference between different design standard was compared. The results showed that major changes happened in the long-term deformation of beam body if spatial creep effect was considered. The vertical deflection of the shell element increased about 25% than that of the beam model. Vertical deflection value based on B3 model was larger than that based on JTG D62—2004 design standard and TB design standard, and B3 model should be utilized to compute long-term deformation of box girder bridge.

Key words: heavy haul railway, spatial beam element, B3 model, ANSYS, space creep effect, spatial shell model
