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

Abstrak: Kegiatan pengabdian kepada masyarakat ini bertujuan merancang desain eksterior kisi-kisi pada koridor sekolah dasar mitra sebagai solusi terhadap permasalahan tampias hujan dan panas berlebih yang mengganggu kenyamanan aktivitas belajar. Koridor yang menjadi fokus kegiatan merupakan penghubung antara ruang kelas dan perpustakaan. Mitra kegiatan melibatkan pihak sekolah, khususnya guru dan pengelola sarana prasarana, yang berperan aktif dalam diskusi dan evaluasi. Solusi yang ditawarkan berupa desain kisi-kisi eksterior dengan rangka besi hollow dan penutup Aluminium Composite Panel (ACP) bermodul 1×1 meter berwarna putih dan abu-abu. Metode pelaksanaan meliputi observasi lapangan, diskusi partisipatif, serta perancangan desain konseptual dengan mempertimbangkan aspek fungsional, estetika, dan kondisi iklim setempat. Monitoring dan evaluasi dilakukan melalui observasi serta wawancara reflektif. Hasil evaluasi menunjukkan bahwa 90% responden menilai desain sesuai kebutuhan sekolah dan layak dijadikan acuan renovasi. Rancangan ini diharapkan mampu meningkatkan kenyamanan serta kualitas lingkungan belajar.Abstract: This community service activity aims to design an exterior grid for the corridor of the partner elementary school as a solution to the problems of rainwater leakage and excessive heat that interfere with the comfort of learning activities. The corridor that is the focus of the activity is a connector between classrooms and the library. Partners in the activity include the school, particularly teachers and facility managers, who play an active role in discussions and evaluations. The proposed solution is an exterior grille design with a hollow iron frame and 1×1 meter white and gray aluminum composite panel (ACP) coverings. The implementation method included field observations, participatory discussions, and conceptual design planning that took into account functional aspects, aesthetics, and local climate conditions. Monitoring and evaluation were carried out through observations and reflective interviews. The evaluation results showed that 90% of respondents considered the design to be in line with the school's needs and suitable as a reference for renovation. This design is expected to improve comfort and the quality of the learning environment.

Abstract

Tied steel arch bridges are commonly used due to their structural efficiency and aesthetic value; however, excessive mid-span deflection remains a critical design issue. While previous studies indicate that bottom bracing can enhance stiffness, the optimization of bracing configurations at the mid-span has not been sufficiently investigated. This study evaluates the influence of different bottom bracing configurations on mid-span deflection in tie-beam steel arch bridges. Numerical analysis based on the finite element method was conducted using SAP2000 v.22 on four bridge models with identical geometry, loading conditions, and a total bottom bracing weight of 10 kg. The bridge span was 4 m with an allowable deflection limit of 5 mm. The results show that all configurations satisfy the deflection criteria, with the X-bracing configuration yielding the smallest mid-span deflection. These findings contribute to the understanding of optimal bottom bracing configurations in steel arch bridge design, supporting efficient structural performance in engineering applications.

Abstract

Abstract: The village of Pagersari, located in a highland area, possesses potential natural resources that can be developed, and its strategic location makes it suitable to become a rest area. However, the development of the rest area is still in the planning stage, with the main issue being the lack of knowledge among village officials and the local community regarding construction and cost estimation. Therefore, an "Edu Construction" program is needed to enhance the knowledge and competencies of the village community and officials in construction-related work. The "Edu Construction" program consists of three phases: Preparation (including surveys and needs analysis), Implementation (involving layout design, E-modules, training, and mentoring), and Evaluation and Reporting. The results include the rest area layout design, a web-based E-module, as well as training and mentoring for cost estimation preparation. Subsequent phases involve the publication of the E-module, activity evaluation, and the preparation of activity reports. The aim is to advance the Pagersari Village rest area and enhance the knowledge and skills of the community and village officials in construction-related matters. Abstrak: Desa Pagersari, yang terletak di dataran tinggi, memiliki potensi sumber daya alam yang dapat dikembangkan, dan lokasinya yang strategis membuatnya cocok untuk menjadi rest area. Namun, pengembangan rest area masih dalam tahap perencanaan, dengan masalah utama yaitu minimnya pengetahuan aparat dan masyarakat desa dalam hal konstruksi dan estimasi biaya. Oleh karena itu, diperlukan program "Edu Construction" untuk meningkatkan pengetahuan dan kompetensi masyarakat dan aparat desa terkait pekerjaan konstruksi. Program "Edu Construction" mencakup tiga tahap: Persiapan (termasuk survei dan analisis kebutuhan), Pelaksanaan (termasuk pembuatan desain layout, E-modul, pelatihan, dan pendampingan), serta Evaluasi dan Pelaporan. Hasilnya adalah desain layout rest area, E-modul berbasis website, serta pelatihan dan pendampingan untuk penyusunan estimasi biaya. Tahap selanjutnya termasuk penerbitan E-modul, evaluasi kegiatan, dan pembuatan laporan kegiatan. Tujuannya adalah memajukan rest area Desa Pagersari dan meningkatkan pengetahuan serta keterampilan masyarakat dan aparat desa terkait konstruksi
