Abstract

Cold formed steel (CFS) sendiri memiliki dasar pelat yang sangat tipis sehingga cepat untuk mengalami tekuk pada awal deformasi. Mudahnya kondisi CFS megalami kegagalan tekuk, maka peneltian CFS sangat memperhatikan dalam desainnya terhadap sambungan balok ke kolom. Desain sambungan tersebut ditujukan pada komponen sambungan seperti baut dan pelat penyambung seperti rectangular gusset plate, T gusset plate, seat angle, web angle, dan haunched gusset plate. Sambungan ini tidak memerlukan pengelasan dan hanya memerlukan instalasi sederhana. Beberapa tahun belakangan ini pengembangan penelitian terhadap gusset plate sudah semakin dikembangkan terutama tipe haunched gusset plate (HGP). Dalam paper ini akan disajikan metode analisis menggunakan Finite Element Method (FEM) terhadap sambungan HGP dengan tebal pelat 10 mm, baut diameter 12 mm, serta balok dan kolom berukuran C30024. Prangkat lunak yang digunakan untuk membantu dalam menganalisis FEM yaitu ANSYS WORKBENCH. Beberapa metode yang akan dilakukan yaitu menentukan material data, permodelan sambungan, meshing, penentuan kontak analisis, dan melakukan solve analysis. Setelah metode dilakukan maka keluar output berupa nilai defleksi, momen, dan rotasi serta kontru deformasi dan tegangan pada struktur sambungan. Deformasi maksimum yang terjadi yaitu sebesar 29,5 mm. Kesimpulan akhir yaitu perbandingan antara hasil FEM dengan hasil  eksperimen dengan telah dilakukan oleh peneliti sebelumnya.Perbandingan nilai momen rotasi tersebut berkisar 28,89%.

Abstract

Human mobility in Bandung City cannot be avoided. Congestion and travel distance make walking a popular choice. Accessibility is measured by walking distance (400–800 m) and walking time (10–15 minutes). Route characteristics affect walking effort, determining accessibility quality. Ganesha Campus ITB, especially Dayang Sumbi Gate, has high pedestrian traffic. This study assesses walkability using Permeability Framework, Walking effort approach, and Walkability Index. Results shows the route to McDonald's Dago via Jl. Sumur Bandung has the highest Walking Effort and Permeability: 3155 m (normal)–2300.26 m (opposite) and 5.836 (normal)–4.939 (opposite). The best road by walkability index is Jl. Ir. H. Djuanda While the Worsts one is Jl. ITB IX.

Abstract

The increasing use of cold-formed steel (CFS) in building structural systems requires an accurate understanding of connection behavior, particularly beam–column connections which have an important role in transferring moment and rotation. One connection type that has been developed is the haunched gusset plate (HGP), which is designed to improve stress distribution and rotational performance of the joint. This study aims to analyze the moment–rotation characteristics of HGP connections in CFS beam–column structures with double channel sections using a numerical approach based on the Finite Element Method (FEM) implemented in ANSYS Workbench. The numerical model was developed based on the IJT-BGJ-9 experimental specimen from previous studies as a validation reference, considering material nonlinearity, boundary conditions, contact interaction, and explicit bolt modeling. The analysis focuses on the evaluation of joint strength capacity, stiffness capacity, and ductility capacity in accordance with the provisions of BS EN 1993-1-8. The results show that the FEM moment–rotation curve has very good agreement with the experimental results, with a rotation difference of 0,43% and a final stiffness difference of 1,30%. The HGP connection is classified as a semi-rigid, partial-strength, and ductile joint. These findings demonstrate that the developed FEM model is able to accurately represent the actual behavior of the connection and can be used as a reliable and efficient evaluation tool for the analysis and design of cold-formed steel frame connections.

Abstract

Infrastructure development in the education sector plays an important role. Universitas Indo Global Mandiri supports educational infrastructure development through the provision of student rental flats (Rusunawa). One of the key aspects in rusunawa construction is the structural quality, which must be capable of resisting loads and ensuring occupant safety. Concrete, as the primary structural material, significantly influences the performance of the structure. This study aims to compare the structural design of the Universitas Indo Global Mandiri rusunawa using concrete compressive strengths of fc′ 25 MPa and fc′ 30 MPa, and to determine the differences in internal forces and reinforcement requirements. The building was designed using a Special Moment Resisting Frame (SMRF) system subjected to dead, live, wind, and earthquake loads. Structural analysis was conducted using SAP2000 to obtain internal forces, while Microsoft Excel was used to determine reinforcement requirements. The results showed that beams and columns with fc′ 25 MPa concrete produced lower internal forces than those with fc′ 30 MPa concrete. However, the variation in concrete compressive strength did not affect the required reinforcement. The main beams required 3D16 support reinforcement and 2P10–190 shear reinforcement, secondary beams required 2D16 support reinforcement and 2P10–190 shear reinforcement, while columns required 3D13 longitudinal reinforcement and D10–200 transverse reinforcement.

Abstract

RSUD Siti Fatimah Az-Zahra in the province of South Sumatra is the largest regional government hospital in Indonesia. The hospital functions not only as a place of medical care, but also as a complex health service center, which requires a special and well-integrated building structure design. Analysis of the building structure using static equivalent force analysis and dynamic response spectrum analysis methods within the framework of the upper structure with a focus on comparing displacement and base shear. The purpose of this study is to determine the results of displacement and base shear, and to determine the results of comparison of displacement and base shear results using equivalent static and dynamic response spectrum methods. The results of the research conducted using SAP2000 software calculated the displacement that occurred using the equivalent static method shifted by 1.08% in the X direction and by 3.97% in the Y direction, then using the dynamic spectrum response method shifted by 1.41% in the X direction and by 3.56% in the Y direction, while the base shear for the resulting scale factor in the X direction was 1.412 and for the Y direction was 1.119. The displacement comparison results for the equivalent static method in the X direction are smaller than those for the dynamic spectrum response method in the X direction, and for the equivalent static method in the Y direction are larger than those for the dynamic spectrum response method in the Y direction, while for the base shear calculation, the equivalent static method is larger than that for the dynamic spectrum response method, based on the SNI-1726-2019 reference calculated using SAP2000 software, the structure is still in the SAFE category.
