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

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.
