Research on Loading Model of Bracket in Multiple Mass Concrete Placement

Abstract:

Parametric design language in finite element analysis software ANSYS is adopted to establish the analysis model in the construction of the 0# block of a rigid frame bridge on the pier bracket in different times, simulating the placing process of the 0# block of this bridge with three times, and analyzing and understanding the deformation and stress distribution of the bracket and 0# block during each placement of the 0# block. The load participation coefficient of the concrete placed in the 0# block in subsequent 0# block construction is obtained by the analysis and comparison of the stresses of the bracket’s longitudinal beam in the 0# block placed in one time and the 0# block placed in different times. In the meantime, the numerical calculation is proved to be reliable and correct based on the calculation of multiple software programs and the comparison of field test data. These conclusions are meaningful for the design of the bracket for multiple mass 0# block placements, load calculation, and 0# block construction monitoring.
