    This Research presents a comparative evaluation of steel structures designed using Indian Standard (IS) and American Institute of Steel Construction (AISC) codes, focusing on structural performance, material strength and deformation behavior. The analysis reveals significant differences due to variations in design philosophy, safety factors and material specifications. AISC W18X46 sections demonstrate superior working load capacity (3185.78 kN) compared to ISMB300 (2387.47 kN), while IS100X100X8 angles exhibit higher yield strength than AISC L4X4X5/16. AISC sections show lower shear strength, potentially due to more conservative evaluation methods. Deflection analysis indicates AISC beams outperform IS beams by reducing deflections by 6.5% to 12%, attributed to higher moments of inertia and stricter serviceability limits. Axial force values in AISC beams are 5.47% to 8.07% lower, suggesting optimized load distribution and better material utilization. Similarly, bending moments are reduced by 3.77% to 6.18% in AISC designs, reflecting improved structural efficiency. Stress ratio variations between the two codes remain minimal (0.11%–0.20%), ensuring safety in both approaches. The study concludes that while both IS and AISC provide safe structural designs, AISC offers enhanced performance and efficiency, making it preferable for high-performance, cost-effective applications depending on project demands and regional design standards.

    • Seasoning Enhances Durability : Effective seasoning reduced moisture content, increasing bamboo’s density, durability and resistance to biological degradation. • Surface Treatments Improve Stability : Tar + kerosene treatment minimized water absorption and dimensional changes, ensuring long-term structural integrity in outdoor applications. • Structural Optimization for Load-Bearing : Bamboo natural geometry, with thicker walls at the bottom, supports higher loads, guiding its strategic use in construction. • Strength Variation with Nodes : Bamboo without nodes exhibited superior tensile and compressive strength, while nodes provided reinforcement, necessitating careful design considerations. In this study to explore bamboo as a substitute for conventional steel reinforcement in for concrete elements, the Dendrocalamus strictus variety is selected for its favorable tensile properties. This bamboo, aged three to four years and seasoned for one year with a length of 3 to 4 meters. The chosen bamboo pieces had an outer diameter ranging from 32 mm to 48 mm at the base, with an average node spacing of 345 mm. Only the basal and middle segments of defect-free and well-seasoned culms were used. Tension tests revealed that the ultimate tensile strength for specimens without nodes reached up to 308.36 N/mm², while specimens with nodes showed a tensile strength of up to 133.6 N/mm². For the present investigation, the tensile strength and deflection values of specimens with nodes are considered, reflecting the typical conditions in practical applications. This selection ensures the bamboo's reliability and performance as a reinforcement material, considering the inherent variability in tensile strength due to the presence of nodes.

    This experimental study focuses on analyzing the compositional characteristics of Coconut Shell Fiber-Reinforced Concrete (CSFRC) under varying impact loading conditions. To conduct the experiments, a specially designed falling weight hammer system was utilized to apply cyclic impact loads to both one-time and recurrently tested specimens. The study evaluated two types of specimens: plain Cement Concrete (PCC) and CSFRC, with dimensions of 150 mm in diameter and 300 mm in height for larger specimens and 100 mm in diameter and 150 mm in height for smaller ones. The impact testing involved subjecting these specimens to critical impact load energies using a drop hammering impact load test. Several parameters, including impact pressure, elastic modulus exchange, and the dynamic instability factor (DIF) of CSFRC, were studied during a single load impact test. Through a series of impact tests, the study established a correlation between the maximum compressive stresses experienced and the significant damage caused by the impact loading. It was observed that the maximum critical impact stress levels were linked to the peaks in impact loading, leading to a conclusive finding. This study also focuses on investigating the behavior of Coconut Shell Fiber Reinforced Concrete (CSFRC) under diverse loading conditions. To assess the performance of CSFRC, we subjected specimens to varying types and levels of loading. These specimens, along with plain Cement Concrete (PCC) reference samples, were prepared in two different sizes: 150 mm in diameter and 300 mm in height for larger specimens and 100 mm in diameter and 150 mm in height for smaller ones. The impact testing involved exposing the CSFRC specimens to critical impact load energies using a drop hammering impact load test. Throughout these tests, we examined impact pressure, elastic modulus exchange, and the dynamic response represented by the dynamic increase factor (DIF) specific to CSFRC. Furthermore, we conducted a comparative analysis to assess and contrast the primary failure modes and risks associated with PCC and CSFRC samples under varying loading conditions. Through a series of rigorous impact tests, we established a conclusive relationship between the maximum compressive stresses reached and the extent of damage incurred due to the impact loading. Our findings illuminate how CSFRC behaves and responds to different loading conditions, shedding light on its suitability for various applications in construction and engineering.

    This study investigates the feasibility of using concrete reinforced with a blend of coir and bamboo as a sustainable building material. Bamboo, known for its robust yet lightweight nature, serves as a natural reinforcement with high tensile strength, enhancing structural properties. Various lengths and diameters of bamboo reinforcements are coated with gloss enamel and black coal tar for durability is employed in this study. Coir is sourced from coconut husks and recognized for its strength and resilience in composite construction. The research explores the combined action of coir rope fibers and bamboo to improve tensile strength, flexural strength, and durability in concrete slabs. Twelve slabs are examined with featuring of conventional reinforcements, dried bamboo, gloss enamel-painted bamboo and black coal tar-coated bamboo with different diameters. The mechanical properties of concrete specimens are subjected to compressive force test according to IS 456:2000. While steel-reinforced slabs exhibit superior strength, it is noteworthy that 1.75% of black coal tar-coated bamboo reinforcement with coir rope performs comparably to traditional steel reinforcement in conventional concrete.

    <p>The world is witnessing a boom-in construction industry due to urbanization which leads to over-exploitation of primary resource to match the demands and also increase the land pollution. The advent of nano engineering technology has a significant impact on cementitious materials, particularly graphene oxide which has piqued the interest of several researchers. Because graphene oxide not only provide strength, but it also makes the material more robust and weather resistant. Perhaps more crucially we can minimise the quantity of material necessary to build concrete by incorporating graphine oxide. The macro level workability strength behaviour flexural behaviour and water absorption test of the inclusion of graphene oxide in cement will be explored in this research. Graphene oxide is often available in powder form and it should be combined with water to make a paste before being mixed with concrete for best effects. In this study varied percentages of GO from 0% to 0.05% are employed to determine the optimal proportion of GO by weight of regular portland cement to achieve high strength. Polycorboxylate ethers will be employed as a super plasticizer in this study.</p>

    Investigating the mechanical properties of high-performance concrete (HPC) employing mineral admixtures including fly ash, silica fume, and graphene oxide was the primary goal of this investigation.The HPC utilised in this study was created using regular OPC fine and coarse aggregate, portable water, and mineral and chemical admixtures such as fly ash, silica fume, and graphene oxide at varied replacement levels, in addition to super plasticizer.In compliance with IS 10262:2019, which calls for the use of HPC mix grade M60 with a w/c ratio of 0.33, super plasticizer was added to the concrete to increase its workability.In order to evaluate different mixtures, cube and cylinder beam specimens with extra mechanical and durability features were all cast.Partial cement replacements of 0%, 5%, 10%, and 15% composed of fly ash and silica fume, graphite oxide with a concentration of 0.04 % were used in the casting of M1 through M4, respectively.The concrete's mechanical behaviour, which was measured in terms of compressive strength, was then put to the test seven, fourteen, and 28 days after it was cast.The results of the tests demonstrate that including mineral admixtures usually improves the combinations' mechanical and durability attributes.
