Abstract

Industrial building construction activities are widely regarded as high-risk operations due to the complexity of tasks and the involvement of various hazardous elements. Workers are frequently exposed to dangers such as falling from heights, being struck by moving or falling objects, electrical hazards, exposure to toxic substances, and musculoskeletal strains. These risks necessitate a systematic and comprehensive approach to hazard identification and risk control to ensure worker safety and operational continuity. This review article aims to synthesize relevant scientific literature published between 2018 and 2024 from reputable databases such as Scopus and Sinta, focusing on the identification of workplace hazards, methods of risk analysis, and implementation of effective mitigation strategies. The narrative review method was employed to gather and analyze findings from 28 selected studies that met predefined inclusion criteria. Results indicate that structured risk assessment tools—such as Hazard Identification Risk Assessment and Determining Control (HIRADC), Job Safety Analysis (JSA), and bowtie analysis—combined with the application of ISO 45001-based Occupational Health and Safety Management Systems (OHSMS), contribute significantly to minimizing accident rates. The review emphasizes the importance of integrating technical measures, administrative controls, and continuous safety training to develop a resilient and safety-oriented work culture in the industrial construction sector.

Abstract

This study investigates the mechanical behavior of jute/epoxy laminated composites when applied as external reinforcement to cylindrical concrete specimens subjected to splitting tensile stress. Natural fiber-reinforced composites, such as jute, have gained significant attention in recent years due to their environmental sustainability, low cost, and reasonable mechanical performance. The primary objective of this research is to evaluate the effectiveness of jute laminate sheathing in improving the tensile strength of cylindrical concrete structures using numerical simulation. A finite element method (FEM) approach was implemented in ANSYS Workbench 2022 to model and simulate various configurations, including specimens without laminates and with one, two, and three layers of jute/epoxy laminates. The model geometry was based on standard cylindrical specimens with a diameter of 50 mm and a height of 150 mm. Material properties were defined based on experimental data, and appropriate mesh and boundary conditions were applied. Results showed that the addition of jute laminates significantly enhanced the splitting tensile strength, with the highest increase of 241% observed in specimens with three layers. The simulation results were validated against experimental data using ANOVA, confirming a strong correlation (p = 0.5). This indicates that the ANSYS-based FEM simulation is a reliable tool for predicting the mechanical behavior of natural fiber-reinforced composites in structural applications.
