Specify the analysis conditions for a heat of hydration analysis. midas Civil follows the procedure noted below for a heat of hydration analysis. 1.Select Model > Properties > Time Dependent Material(Creep/Shrinkage) and Model > Properties > Time Dependent Material(Comp. Strength) to specify the time dependent properties. And then link the general material properties and time dependent material properties in Model > Properties > Time Dependent Material Link. 2. Enter the relevant data necessary for the heat of hydration analysis in the sub menus of Load > Heat of Hydration Analysis Data. 3. In Analysis > Heat of Hydration Analysis Control, specify the temporal discretization factor, initial temperature, location of stress output and whether or not to include Creep and Shrinkage. 4. Select the Analysis > Perform Analysis menu or click 5. Once the analysis is completed, check the analysis results in contours, graphs and animation. |

Specify a stage to be considered as the final construction stage of the heat of hydration analysis. Last Stage Other Stage
Enter the Temporal discretization Factor,
Specify the initial temperature used in the heat transfer analysis.
Specify the location in solid elements for stress output. Center: Use the stresses at the centers of the solid elements to represent the stresses of the individual elements. Gauss: Use the stresses at the Gauss points as the nodal stresses. Nodal Point: Interpolate the stresses at the Gauss points for nodal stresses.
Account for Creep and Shrinkage in the analysis. Type Creep Calculation Method Select one method for calculating creep between the method using Code (General) and the method using effective modulus of elasticity (Effective Modulus). General When General is selected, creep and shrinkage are accounted for according to the Code specified in Time Dependent Material (Creep/Shrinkage). Modify Modulus of Elasticity Effective Modulus of Elasticity is an approximate calculation method to account for creep. The reduction factor, phi1, is applied to Modulus of Elasticity from 0(day) to n1(day). The reduction factor, phi2, is applied to Modulus of Elasticity after n2 (day). Between n1 and n2, the reduction factor is interpolated. Convergence for Creep Iteration Number of Iterations: Maximum number of repetitions Tolerance: for convergence
Select whether or not to use Equivalent Age based on Time and Temperature for Heat of Hydration Analysis.
Check this option to include Selfweight. Enter "-1" to consider the selfweight in the gravity direction.
