Finite Element Analysis of Thermal Stress for Cable-Stayed Bridge Tower with Cracks

The application of ABAQUS in thermal stress analysis of mass reinforced concrete, focusing on the temperature field, crack propagation, ABAQUS modeling, finite element analysis approaches of thermal stress, is reviewed first in this paper. Then, based on the observation of one cable-stayed bridge pylon, a finite element analysis of existing crack tips in temperature stress is done, and the simulation results are compared with the measured ones to verify the validity and accuracy of the finite element calculation.
