Numerical Modeling of New Conceptions of 3D Printed Concrete Structures for Pumped Storage Hydropower

This paper explores the possibilities of pumped storage hydropower (PSH), checking the possibilities of using new engineering tools such as 3D printing. The use of such technology for concrete has gained rapid development in recent years due to the advantages in structural optimization and economy with formwork in conventional construction. Practical engineering applications have proven the applicability of 3D printing in large-scale construction of building components, and compared to conventional manufacturing methods, this advanced technique has several advantages and offers almost unlimited potential for geometric complexities. We explore new design conceptions with the help of numerical modeling in two ways: (i) during the early ages considering the phenomena of hydration; (ii) after hardening of concrete verifying the integrity of the structure. The results indicated that numerical modeling can point to new solutions that will help address the challenges posed by greater sustainability in energy generation and storage in the 21st century.
