This book presents the proceedings of the 18th East Asia-Pacific Conference on Structural Engineering and Construction (EASEC-18), held in Chiang Mai, Thailand on November 13-15, 2024. Under the theme "Construction Engineering for a Responsible Growth and Sustainable Future," the conference brought together novel research and advancements in materials science and engineering in construction, foundation and geotechnical engineering, resilient structures and design for natural disasters and extreme events, structural analysis and design, smart infrastructure systems and construction management, advanced construction techniques, operations, and maintenance, transportation engineering, circular and green construction economy, and professional practices and engineering education. Contributing to the overarching conference theme, specialized symposia were also organized to address salient issues on structural stability and structural vibration control of engineering structures against multiple dynamic hazards, seismic resilient structures, structural health monitoring, Bayesian system identification of civil engineering structures, and advanced concrete technology and composite structures.
