Experimental investigation of textile reinforced concrete thin-wall panel bolted connections

Abstract

Textile Reinforced Concrete (TRC) is a composite material that combines fine-grained concrete with textile fibers to create a new building material with improved mechanical properties. TRC, an innovative thin-wall precast panel construction solution, offers excellent tensile strength, crack resistance, and durability. The behavior of bolted joints in textile-reinforced concrete thin-wall panels was experimentally studied in this research. The investigation focused on three types of connections: moment joints, shear joints, and half-box connections. The study aimed to examine the structural performance of these joints under different loading conditions and identify the failure modes. Ten specimens were tested, and the results were analyzed to determine the relationship between applied load and joint behavior. This research provides valuable information for the design and optimization of bolted joints in textile-reinforced concrete thin-wall panels.
