Abstract

Arch bridges represent a widely favoured structural form, celebrated for their inherent efficiency and aesthetic appeal. Variations in arch geometry, such as circular and parabolic shapes, exert a significant influence on both the structural stability and load distribution within the design. This research endeavours to conduct a comparative analysis of how distinct arch geometries—specifically circular and parabolic—impact the structural stability of arch bridges. The investigation centres on a case study utilising a model arch bridge from the 19th Indonesian Bridge Competition (KJI) in 2024. The methodology employed involves structural analysis facilitated by SAP2000 v.24 software, adhering strictly to the guidelines set forth by KJI XIX 2024 and SNI 1729:2020 for comprehensive evaluation. Key parameters subjected to analysis included internal forces, stress, strain, deflection, and material efficiency. The analytical findings reveal that the bridge model incorporating a parabolic arch demonstrates superior performance. While the maximum axial forces in the arch rib and hangers were higher in the parabolic model, this model exhibited substantially lower bending moments in the arch rib (45.36 kNmm) and longitudinal girder (32.55 kNmm) when compared to the circular arch model (86.51 kNmm and 87.41 kNmm). Furthermore, the maximum deflection observed in the parabolic model (1.75 mm) was notably less than that of the circular model (2.21 mm). In terms of material consumption, the parabolic arch bridge model proved more efficient, with a total weight of 19.19 kg, making it 51.9% lighter than the circular arch bridge model, which weighed 37 kg. In conclusion, the parabolic arch form imparts enhanced structural stability and greater material efficiency, proving more effective in channelling loads primarily into pure compressive forces, thereby mitigating overall bending moments and deformations.

Abstract

Columns are the most important element in a structure. Indonesian concrete regulations SNI 2847-2013 states that columns are elements that receive a minimum axial and bending loads of 0.1 Pu. Column damage can occur due to overloading damage, poor detailing in design, poor construction, etc. However, the most frequent damage is post-earthquake damage. The easiest reinforcement is the concrete jacketing method. The reinforcement material used in this research is bamboo. The test was done using the Quasi Static Loading Test method with lateral loads according to the displacement control and constant axial load. The results showed that the reinforcement by concrete jacketing from the initial dimensions of 15x15x90 cm to 21x21x90 cm showed the increase of lateral capacity, ductility, stiffness, and energy dissipation. In addition, it can be seen that the effect of reinforcement on both damaged and undamaged columns is less significant, which means that reinforcement can restore the initial capacity of existing test specimens to exceed 100%.

Abstract

Sektor konstruksi menghadapi tantangan ganda dalam mencapai efisiensi material sekaligus mencapai efisiensi material sekaligus meminimalkan dampak lingkungan. Metode estimasi volume pekerjaan (Quantity Take-Off/QTO) konvensional berbasis gambar 2D masih banyak digunakan di Indonesia dan rentan terhadap human error, yang berpotensi memicu pembengkakan biaya sekaligus peningkatan jejak karbon akibat kelebihan material. Penelitian ini bertujuan mengimplementasikan Building Information Modeling (BIM) secara terintegrasi hingga dimensi ke-enam (BIM 6D) untuk mengektraksi volume pekerjaan secara otomatis dan menganalisis emisi karbon pada proyek konstruksi yang menjadi studi kasus seluas 3.060 m2. Metode yang digunakan adalah pendekatan kuantitatif deskriptif dengan permodelan 3D menggunakan Autodesk Revit, ekstraksi QTO melalui fitur Schedule/Quantities, dan analisis embodied carbon fase A1-A3 menggunakan add-in bim.com. Hasil QTO menunjukkan total pekerjaan beton menghasilkan 543,95 m3 dan pekerjaan baja sebesar 67.744,25 kg. Analisis karbon menghasilkan total emisi sebesar 357,84 kg /m2 GFA atau setara 1.095 ton , dengan penyumbang terbesar adalah elemen dinding (115 kg /m2) dan atap (100 kg /m2). Nilai ini berada jauh dibawah batas sustainbility budget non-domestik sebesar 1.400 kg /m2. Penelitian ini membuktikan bahwa impelementasi BIM 6D secara terintegrasi mampu menghasilkan perencanaan yang efisien secara material sekaligus ramah lingkungan
