Finite element thermal analysis of a roller compacted concrete (RCC) dam

When concrete and water are mixed during dam construction, the resultant heat of hydration can lead to thermal stresses. Those stresses can result in cracking and reduce the durability of the dam.

Chetan Aggarwal’s technical paper is featured in the International Journal on Hydropower & Dams. He presents a finite element thermal analysis that explores how temperature evolves inside a roller compacted concrete (RCC) dam during construction. He also explores how construction timing, weather, and placement practices influence cracking risk.

The study uses nonlinear incremental structural analysis using MIDAS software to analyze the tallest section of an RCC dam. By simulating heat of hydration, ambient temperature variations, and convection effects at different construction stages, the analysis simulates induced tensile stresses on the structure. The results serve as a basis for optimizing construction schedules, implementing temperature control strategies, and enabling long-term structural integrity and durability of the dam. The findings highlight how informed planning can reduce cracking risk and help deliver safer, longer‑lasting infrastructure.
