Numerical Analysis of 3D-Printed Permanent Formwork in Multi-Story Building Construction (2025-10)¶

This paper investigates the feasibility of utilizing 3D Printed Concrete Technology (3DCP) for post-war building reconstruction in Ukraine. A structural system based on permanent formwork for columns and beams is analyzed. Through numerical analysis and modeling, it demonstrates that 3DCP offers cost-effective solutions, reducing construction time and labor. Results show that 3DCP elements of permanent formwork require no additional reinforcement for elements up to 9 m in length with a two-span support scheme, ensuring structural integrity while minimizing costs. The research also explores various structural configurations with span of main bearing elements from 4.2 m to 9 m, revealing that buildings constructed with 3DCP exhibit small horizontal displacements and accelerations, indicating sufficient spatial stiffness. Quantitative analysis indicates that the total vertical loads can be evenly distributed, meeting the requirements of most residential and administrative buildings. These findings underscore the potential of 3DCP technology to streamline the reconstruction process, improve structural efficiency, and address resource constraints in post-war environments.
