The cracks could reduce the structure’ durability and structural stability. A spatial finite element model analysis on a mass concrete foundation board of a project was established using large-scale finite element analysis software. Temperature stress finite element analysis was carried on model. Numerical simulation analyzed the hydration heat of mass concrete construction phase and calculated the mass concrete’ temperature and stress distribution. Results of numerical simulation of crack control had certain guiding significance to mass concrete construction. Abstract: To meet the demand of high performance of mass concrete in a pile cap of well tower, excessive replacement of fly ash was applied to the mass concrete. Based on the theory of hydration heat of cement, several thermal parameters of mix proportion were analyzed and simulated test analyses and setting time test analyses were conducted in the laboratory.

The results and data collected in the project locale both show that applying excessive replacement of fly ash reduces hydration heat of mass concrete in the pile cap of well tower, which extends setting time in mass concrete and avoids the cracks caused by temperature stress. The results achieve favorable effect and provide reference for design and construction of mix proportion in the project of mass concrete. Abstract: The numerical analysis method is applied to simulate the whole process of bending. Keeping the section dimensions and the types of loads constant in prestressed concrete hollow slab with mid-strength spiral-rib steel wire, strength of concrete, strength of steel bar, reinforcement ratio, span-depth ratio and stretching control stress are analyzed and compared. The influence of strength of concrete, strength of steel bar, reinforcement ratio, span-depth ratio and stretching control stress on ratio of cracking bending moment and design bending moment of prestressed concrete hollow slab is discussed by numerical simulation. Abstract: The relation of tensile strength ＆ temperature stress and concrete fissure was researched firstly, then it showed the causes of late cracks on concrete by theoretical calculation, the result provided a simple theoretical calculation method to avoid concrete fissure. The construction methods to control the fissure was proposed: early strengthening cooling, managing maximum temperature of concrete through lately heat preservation, and overtime to preserving concrete moisture for controlling the late strain on mass concrete.

Jan 19, 2017. Thermal stress analysis was performed to give an estimate of stresses induced by the thermal gradient of the concrete block section and the crack index was used to quantify the. Edge Fusion Software Drivers here. A 1.1 m × 1.1 m × 1.1 m finite element model of the experimental block was constructed in the software package, ANSYS. PDI is the leader in quality assurance systems for deep foundations, pile driving, continuous flight auger analysis. Concrete subjected to thermal loading was done using finite element approach. The transient thermal analysis was done on the concrete and the results were matched with the experimental data available. The finite element software ABAQUS ver. 6.12 was used to study the transient thermal analysis of concrete. In the simulation of concrete temperature by three-dimensional finite element, back analysis of the thermal parameters based on the establishment of improv. Result shows the high efficiency in the back analysis of concrete thermal parameters. Published in: Software Engineering (WCSE), 2010 Second World Congress on.

This research has a great significance for controlling the fissure. Abstract: By using ANSYS software, the finite element model of the foundation for wind turbine generator system is built. On the basis of concrete elastoplastic constitutive, the non-linear contact between the foundation stub, a steel part, and foundation concrete is introduced, the internal mechanical characteristics and law of the foundation which is under the influence of wind with unfixed direction are researched on. The interaction state is attained.
