Structural Engineering Association President Identifies 3 Key Issues in Giant Dome Collapse in Bang Phli

On February 9th at 11:30 AM, Prof. Dr. Amorn Pimanmas, President of the Structural Engineering Association of Thailand, analyzed the massive dome structure collapse in Bang Phli, Samut Prakan, which resulted in four injuries. The collapsed structure was a large steel framework with circular steel columns, large steel trusses, H-beams, and roof panels. Prof. Dr. Amorn noted the steel columns broke at their base, causing the entire structure to fall. He proposed three initial hypotheses for the collapse: 1) Determining the stage of collapse (during or after construction), 2) Investigating potential weak points in steel column-foundation connections, and 3) Examining potential structural stability issues in longitudinal and transverse directions. He emphasized that a comprehensive investigation is necessary, including reviewing construction plans, calculating load-bearing capacities, and examining work process documentation. The structure falls under controlled engineering requirements and must have been designed by a licensed engineer. The Structural Engineering Association will conduct a detailed on-site analysis to determine the exact cause.
