Description

Description This program is associated with the research paper called ‘Degree of hydration-based thermal stress analysis of large-size CFST incorporating early-age creep’ as research data. 1. ThermalStress_APDL This algorithm implemented in the ANSYS software based on the secondary development of APDL was adopted to establish the thermal stress analysis model of large-size CFST based on the hydration degree incorporating the exothermic hydration model, the heat conduction, the stiffness evolution, the creep rectification, and the quasi-static thermal stress. 2. ThermalStressAna_MATLAB This algorithm based MATLAB programming was adopted to establish the analytical model of the thermal stress of large-size CFST, which was used to verify the calculated results through FEM model. After obtaining the temperature results calculated by the FEM model, the analytical model considered the temperature as the thermal load to calculate the thermal stress of large-size CFST. 3. Postprocess_MATLAB This algorithm was mainly used to display the calculated results of ANSYS program including the hydration heat, temperature, equivalent age, mechanical properties, and thermal stress with and without considering creep, as well as related data processing for further drawing or visualization.
