Study on the Calculation of Bending Capacity Based on UHPC Design Codes

Based on ultra-high performance concrete (UHPC) codes of China, France and Switzerland, the comparative calculation and analysis were carried out. Besides, finite element analysis (FEA) is conducted based on MIDAS software. Results of FEA indicated that the maximum bending moment of the midspan section is 25084.11 kN-m. moreover, the calculation results obtained from the above codes meet the requirements of bending moment. Addiction, analysis results of codes indicate that there is little difference in the calculation of bending capacity in those codes. The bending capacity calculated by Chinese, French and Switzerland codes are 39613.3 kN·m, 38423.61 kN·m, and 41067.36 kN·m, respectively.
