Abstract: In the quest for sustainable construction, this study presents a quantitative analysis of reinforced concrete hollow web inverted T-girders, the key to reducing material use while maintaining structural integrity. The investigation zeroes in on the torsional and shear performance of these girders, accentuating the hollow web's role in optimizing structural behavior. Experimentation with Textile Reinforced Mortar (HWIT-G) techniques illustrates distinct effects on load-deflection characteristics: HWIT-G2 enhanced load capacity by 2.36% with a slight deflection increase of 3.79%, suggesting its potential for load-intensive applications. In contrast, HWIT-G3 and HWIT-G4 demonstrated an excellent stiffness boom, with deflection reduced by 68%, but at a 9.45% reduction in load capacity. The performance of HWIT-G5 showed a substantial increase in stiffness and a 78.66% reduction in deflection, but a 34.25% reduction in load capacity. This demonstrates that through the strategic application of HWIT-G, beams can be adapted to specific structural requirements, especially in earthquake-prone areas. It is understood that the cracked condition on the tension side of a hollow-web T-beam may cause damage because of a concrete stress imbalance. The current investigation attempts to assess the efficacy of the hollow guide method of rolling design as a means of saving resources and as a dependable and practical technique for modern engineering.
