Abstract

Research and development of construction materials continue to be carried out, getting materials, cross-sectional shapes, and manufacturing methods that are more efficient than before. Cold-formed steel is a material breakthrough in construction that has advantages over hot-rolled steel. In this paper, the cross-section of cold-rolled steel unlipped channel will be analyzed which is subjected to a combination of axial and bending loads. Investigating elements will be carried out using the finite element method on ABAQUS, and the results of the analysis produce a visualization of the behavior and capacity of the cold-rolled steel section. The cross-section capacity results obtained from the numerical test results will be compared with the predictions given by SNI 7971-2013 or AS/NZS 4600. Existing research in the literature will be used as a reference in conducting numerical analysis and calculating ultimate capacities.

Abstract

The flare stack serves to protect process equipment facilities against unexpected overpressure. This study aims to follow up on previous research that recommends improvements to the flare stack structure based on corrosion findings that occur in the area of the riser stack around the ring connection for the guy wire. By replacing rusty material, it is also necessary to consider modifications to prevent the risk of re-corrosion. Based on current design observations in the connection ring area for guy wire, side cutting is required which can result in water being trapped. This research aims to find out whether by modifying the connection ring for guy wire, this flare structure still has structural reliability when receiving critical outer loads or not. Based on the results of the study, it shows that modifying the geometry of the connection ring guy wire still provides reliable structural performance when receiving critical outer loads. The maximum stress that occurs in the area around the pad eye is 71.2 Mpa with a maximum stress ratio of 0.434 it shows that the value is still quite far from the maximum allowable voltage ratio of 1.0. So it can be concluded by modifying the connection ring for guy wire to prevent the risk of corrosion can be done without causing a decrease in the performance of the structure in withstanding critical outer loads.

Abstract

The accelerated growth of the industrial sector demand reliable transportation infrastructure to facilitate the efficient circulation of commodities and economic progress. The road network in industrial zones is a critical infrastructure that serves as a strategic route essential for supporting surrounding industrial activity. Nonetheless, road damage, including cracks, deformations, and potholes, presents considerable issues by diminishing road capacity to support traffic loads and hastening pavement degradation. The road damage adversely affects both road users and the populations residing nearby. This study analyzes the impact of road deterioration on road users and adjacent communities. The results indicate that road damage substantially affects these groups, with average interpretation ratings of 4.05 for road users and 4.12 for adjacent communities, both classified as "good" in the assessment. These results highlight the necessity for efficient road repair and management to ensure the sustainability of industrial operations and community well-being.
