A Study on Stress Block Parameters
Abstract: The compressive stress distribution in concrete, when mathematically modeled, can be defined by characteristic parameters known as stress block parameters. There are three such parameters, namely, shape factor, k1, depth factor, k2, and maximum stress factor, k3. There are various shapes of stress blocks, like parabolic, equivalent rectangular, equivalent triangular, and rectangular-parabolic. Various standard codes have adopted an equivalent rectangular stress block, whereas the Indian code has adopted rectangular-parabolic stress …

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 …

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 story’s which results in a poor performance against lateral loads. Soft storey mechanism prevails in these cases and …

Review of Amphibious Structures as A Flood Resilience Strategy Around the World
Abstract: Over time, people have settled in communities that are fluvial flood zones and located at low elevations due to limited access to land, strong cultural ties that continue for generations, and economic factors that make relocation nearly impossible. "Our homes are stitched into the landscape," some say, "we have nowhere else to go." However, when the water continues to invade year after year, these populations face a perpetual threat to …

Structural Optimization of FDM-Processed ASA Polymer Frames through Acetone Solvent Welding, Variable Infill Strategy, and Layer Orientation: Experimental Validation via Quadcopter Flight Testing
Abstract: Acrylonitrile styrene acrylate (ASA) is an amorphous terpolymer with superior UV resistance compared to acrylonitrile butadiene styrene (ABS), as its acrylate rubber phase lacks photodegradation-prone carbon–carbon double bonds. This study proposes acetone solvent welding as a polymer joining method to produce monolithic structures from FDM-processed ASA components, addressing three processing challenges: achieving structural continuity through polymer chain interdiffusion at solvent-wetted interfaces, correcting thermal warping via post-print geometric correction during welding, …

Effect of Steel Slag and Bagasse Ash on Strength of Concrete
Abstract: An experimental investigation was carried out to evaluate the strength properties of concrete. The concrete mix of M-50 grade was designed and produced by replacing steel slag partially with fine aggregate and bagasse ash partially with cement. The mix proportions were prepared with varying percentage of bagasse ash including one control mix of steel slag. Bagasse ash in concrete was replaced with 0, to 20% with an interval of 5% …

Application of flux cored arc welding (fcaw) without pre-heating for heavy structures in ship building fabrication & construction of heavy offshore structural steels
Abstract: In fusion welding processes, the reason often given to explain the need for preheating, controlling the inter pass temperature (in multi-pass welds), and post-weld heat treatment (PWHT) is to reduce the risk of residual stresses and it can be removed by heating weldment in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking. During the construction and …
