Hybrid Composite Behavior of Concrete-Filled Steel Tube (CFST) Columns: Review of Collapse Mechanisms and Polymer-Based Enhancements
Abstract: Concrete-Filled Steel Tube (CFST) columns are an advanced hybrid composite system where the steel tube's confinement and the concrete core's load capacity work together to improve structural performance. While commonly used in civil engineering, CFSTs can also be understood within the framework of composite materials, similar to polymer- and fiber-reinforced composites, in which interactions between phases determine strength, ductility, and failure modes. This review compiles experimental and numerical research on …

Structural Integrity Analysis of Reinforced Concrete Frames Under Progressive Collapse Scenarios
Abstract: This study examines how a tall reinforced concrete (RC) frame may gradually collapse under several column removal situations, such as edge, end, center, zigzag, and two-column failures. The study assesses the structural reaction based on displacement, inter-story drift, and Demand–Capacity Ratio (DCR) using nonlinear static pushover analysis carried out in ETABS. According to the analysis, the frame's stability is seriously jeopardized when two nearby columns and end columns are removed, …

The Role of Polymer Chemistry in Developing a Novel Polymer-Based Retromolar Endotracheal Tube
Abstract: This study presents the development and characterization of a novel polymer-based modified endotracheal tube designed for retromolar intubation. The tube is manufactured using medical-grade polyvinyl chloride (PVC) with reinforced polymeric structures to enhance flexibility while maintaining lumen integrity. The incorporation of a preformed lateral curvature mitigates airway resistance and airflow reduction caused by manual bending, ensuring an optimal balance between rigidity and adaptability. Additionally, the integration of polymer-based ligature wires …

Study the Impact of Corrosive Pollutants on Building Materials Corrosion
Abstract: Reinforced concrete structures (RCS) may be made more resistant to corrosion by using fiber reinforced polymers (FRP). One of the primary concerns with reinforced concrete constructions is corrosion. It causes disintegration in building material components by interactions with salts, acids, and alkalis. Both within and outside of reinforced properties, pollutants and effluents accelerate disbanding. When bio-waste and building materials come into contact, microorganisms and macro organisms, grow and emit acid …

Fluid-Structure Interaction Simulation of Parachute by Eulerian-Lagrangian penalty method
Abstract: In general, modeling and simulation of a model consisting of fluid and solid combinations has been considered difficult, and it has become impossible in terms of computer dependencies and accuracy to be analyzed by Fluent or other programs. The parachute evaluation process, which is historically based on a large amount of experimental data, necessitates many falling experiments. These tests can be costly and time-consuming, and they don't always allow for …

Seismic Analysis of Base Isolation for Protection of Rural Building of Different Shapes
Abstract: India is a developing country, more than 50% of Indian population lives in unreinforced masonry structures. Masonry structures are vulnerable to seismic loading and load acting in it’s out of plane, hence performs poorly and sometimes leads to sudden collapse. Collapse of structure not only damages public property but also costs the lives of people. Base isolation techniques for these types of structure can be proven to be beneficial, in …

Multi-Layer Aluminum–Polymer Hybrid Structures for Improved Automotive Impact Performance
Abstract: Layered metal–polymer hybrid laminates have emerged as promising candidates for lightweight automotive structures requiring high impact resistance and structural reliability. In this study, aluminum/glass–epoxy hybrid laminates were fabricated using a symmetric stacking sequence through hot compression molding to evaluate their mechanical and energy absorption performance. Density analysis revealed an average measured density of 2.34 g/cm³, closely matching the theoretical value of 2.36 g/cm³, with a deviation of approximately 1.02%, indicating …
