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

Lake Normalization is a job that aims to improve the structure of the lake shape by moving sedimentation in the lake so that the lake volume increases and can accommodate more water capacity. Lake normalization work uses excavator heavy equipment with hitachi and sumitomo brands. The purpose of this study is to determine the productivity of excavator heavy equipment using the analysis method of PERMEN PUPR No. 28/PRT/M/2016 and determine the number of heavy equipment needed in lake normalization work. Based on the results of the analysis that has been done, it is known that the volume of the lake is 98,350 m³ with hourly productivity of hitachi brand heavy equipment 93.72 m³ / hour and productivity of sumitomo brand heavy equipment 84.35 m³ / hour and the heavy equipment needed in lake normalization work is 10 units consisting of 5 units of hitachi brand excavators and 5 units of sumitomo brand excavators.

Abstract

Road construction projects undertaken by the Prabumulih City Government involve contractors as service providers. Therefore, project cost evaluation is required to determine whether contractors obtain a profit or incur a loss during implementation. This study aims to determine the Project Implementation Budget (RAP) based on actual material prices, labour wages, equipment costs, and field conditions, and to compare it with the Cost Budget Plan (RAB) for the Nigata Road Construction Project in Sukajadi Subdistrict, Prabumulih City. Primary data were obtained through field measurements, calculation of work volumes, and preparation of the cost estimate for Segment 2. Secondary data consisted of the project RAB, design drawings, the 2023 Unit Price Analysis, and the research location map. The RAB and RAP were calculated using the method applied by the Prabumulih City Public Works and Spatial Planning Agency, particularly in determining coefficients for each work item. The results showed that the RAP for the Nigata Road Construction Project amounted to IDR 862,024,101.46. The comparison between the RAB and RAP indicated a difference of 14.986%. This difference may represent the contractor’s potential profit margin, depending on actual expenditures and conditions encountered during project execution in the field and effective management of available project resources.
