Abstract
Recent advancements in 3D printing concrete (3DPC) enable the fabrication of complex structural components with enhanced structural performance and optimized material distribution. In this regard, we studied a permanent 3DPC formwork designed to support all loads for ribbed slab construction without temporary shoring, leveraging 3D printing’s geometric freedom and topology optimization alongside post-tensioning technology. While our previous study introduced a topology-optimized formwork with demonstrated improvements in structural performance and material efficiency, its post-tension capacity, particularly at overlap regions, remained uncertain. This paper presents load transfer test results assessing the structural behavior of the topology-optimized 3DPC formwork under the desired PT force, ensuring it can withstand loading without premature failure.
