摘要:
This research analyzes the calculation method of the moment redistribution coefficients of the ultra-high performance concrete (UHPC) continuous beams based on nonlinear theory to study the moment redistribution performance of the HRB500-reinforced UHPC continuous beams. A calculation program is also compiled. The program accuracy is verified by comparing the results derived herein with the existing test results. The moment redistribution coefficients of 22 simulated HRB500-reinforced UHPC continuous beams are obtained through a numerical analysis under normal service and ultimate load limit states. The simulation results show the formula for the moment redistribution coefficients as β=-3.541ξ+0.867, where the independent variable ξ is equal to the relative height of the compressive region of the intermediate support section. Considering the limit of the maximum crack width to be less than 0.2 mm in the serviceability limit states, β is suggested to be equal to 0.4 when ξ is less than or equal to 0.13.β is equal to 0.1 when ξ is greater than or equal to 0.21.Moreover, β is calculated using a linear interpolation method when ξ is greater than 0.13 and less than 0.21. © 2016, Editorial Department of Journal of HEU.
