Abstract: Textile reinforced cement (TRC) composites are increasingly studied as a material for struc-tural stay-in-place formwork for concrete structures, because elements with low thickness and relative high mechanical capacities can be produced. Current envisioned formwork applications - beams, slabs, columns - do not exploit another advantage of TRC’s, namely that the flexible textile reinforcement allows an exclusive freedom of form. With TRC, freeform moulds are easily prefabricated to serve as structural formwork for shells, facilitat-ing the construction on site. This paper investigates the contribution of TRC formwork to the loadbearing behaviour of concrete shells. Tests are performed on a TRC reinforced spherical shell of 2m span and 200mm height, subjected to a distributed load. The experi-ment is compared to a numerical simulation performed in the finite element software Abaqus. The test shows promising results for TRC as reinforcement as the TRC layer con-tributes significantly to the concrete section. The finite element model shows similar behav-iour as monitored during the test. This model allows to further develop the design methods for concrete shells with a stay-in-place TRC formwork and reinforcement. With the use of TRC composites, a more efficient and faster construction method for concrete shells is just around the corner.
