Study on the Response of Strengthening Strategies for Masonry-infilled Open Ground Storey Framed Building
Abstract: The strengthening of reinforced concrete (RC) frame buildings with masonry infill wall and with open ground storey is a very timely and significant topic because of the poor performance against seismic action. The absence of infill walls in the ground storey makes the ground storey less stiff and weaker than the all upper storys which results in a poor performance against lateral loads. Soft storey mechanism prevails in these cases …

Optimizing Mechanical Properties of Polypropylene Fibre-Reinforced Coconut Shell Concrete
Abstract: This study investigates the impact of polypropylene (PP) fibre reinforcement on the mechanical properties of coconut shell (CS) concrete. The compressive strength of CS concrete is primarily governed by the strength of CS aggregates, with early-age failure attributed to poor bonding and later-stage failure influenced by aggregate strength. The incorporation of PP fibres significantly enhanced compressive, tensile, and flexural strength. At 28 days, compressive strength increased by 1.2–3.45% in CSF …

Experimental Investigation of Mechanical Properties of AR Glass Fibre Reinforced Self Compacting Concrete
Abstract: The plain cement concrete has brittle in nature and low tensile strength. Self-Compacting Concrete (SCC) is an efficient choice in construction because of its inherent capacity to fill gaps and flow without the need for external vibration. The necessity of self-compacting concrete can be recognized by seeing the growing issue of a trained labour shortage in the building sector. The advantage of SCC is that it allows for an earlier …

Strengthening of RC Structures Using CFRP-Near Surface Mounted Technique
Abstract: This study reviews the literature on fiber-reinforced polymers (FRP) and their applications in near-surface mounted (NSM) applications. Since fiber-reinforced polymer (FRP) composites outperform many conventional steel reinforcing methods in terms of quality, they are nearly entirely dependent on advanced concrete technology. Many structures that will still be in use two decades from now have already been constructed. A portion of these structures must undergo enhancements or be replaced, as they …
