Abstract

Tied-arch bridges are bridges that have high structural efficiency, but are prone to bending instability. This study aims to analyse the relationship between arc geometry variations and the bending stability of tied-arch bridges using the Finite Element Method (FEM) based on SAP2000 software, employing both linear and non-linear approaches. The linear analysis results show that lateral arch deformation occurs, indicating the potential for global lateral instability of the arch. Meanwhile, the non-linear analysis, which considers the significant geometry effect (P-Δ), produces a bending capacity of 7.43-11.69 kN with a maximum deflection of -0.52 mm. Variations in the arch angle were found to affect the critical bending capacity without significantly impacting global deformation. These findings are expected to serve as a valuable reference for designers and structural engineers in determining optimal and efficient arch designs.

Abstract

Safety education for elementary school students is essential for preparing them for emergencies and preventing casualties. However, SD Ummu Aiman, an elementary school in Malang with 653 students, was inadequately equipped in terms of both infrastructure and knowledge to respond effectively in emergencies. This community service initiative aimed to enhance the school’s emergency preparedness and evacuation system by providing evacuation infrastructure, conducting awareness training, simulating emergency drills, and promoting a safety culture through safety induction aimed at fostering behaviour-based safety. The awareness training resulted in an average increase in knowledge of 15.1 points among 53 teachers (p-value < 0.001), and evacuations were completed in under three minutes. It is anticipated that the knowledge and skills transferred to the teachers will be conveyed to the students, who are crucial for developing readiness for emergencies and fostering a safety-minded society in the future.
