JBKD June 2026 Edition, Vol.4 No.2

The June 2026 edition of Jurnal BKD presents seven peer-reviewed articles addressing key issues in structural engineering, water resources, geotechnical engineering, transportation, and environmental engineering. Structural studies examine the flexural capacity of steel beams and the optimization of concentric bracing configurations based on construction cost, fabrication efficiency, and erection methods. Water resources research covers flood water-level analysis and the development of a river-flow velocity prediction model. Geotechnical topics include pile foundation performance and the stability evaluation of tiered retaining walls. This edition also features an assessment of ambient roadside air pollution caused by transportation activities in an urban area.
