Proceedings of the 18th East Asia-Pacific Conference on Structural Engineering and Construction- Volume1

Prof. Tangtermsirikul is currently at the School of Civil Engineering and Technology, Sirindhorn International Institute of Technology (SIIT), Thammasat University, Thailand, and former Director of SIIT. He is also Head of the Construction and Maintenance Technology Research Center of the same Institute. His research fields cover cement replacing materials, utilization of wastes and recycled materials in cement and concrete, technology to reduce CO2 as well as CO2-neutral and CO2-negative concrete, modeling of concrete behaviors, durability and service life of concrete structures, analysis of damaged and deteriorated concrete structures, novel technology in concrete materials and structures such as 3D-printed concrete and UHPC applications, repair and maintenance of concrete structures.Prof. Warnitchai is Chair of the Structural Engineering program at the Asian Institute of Technology (AIT) in Thailand. He obtained his Doctor of Engineering degree from the University of Tokyo in 1990 and has been a faculty member at AIT since 1992. His research expertise encompasses structural dynamics, earthquake engineering, wind engineering, and bridge engineering. Throughout his career, Prof. Warnitchai has significantly contributed to seismic hazard assessment and the development of earthquake-resistant design methodologies. In addition to his academic roles, Prof. Warnitchai has been instrumental in shaping national policies on disaster preparedness and mitigation. He has led research programs for the Thailand Research Fund (TRF) focused on earthquake disaster mitigation and has served as an expert member of the National Disaster Warning System Executive Committee. Prof. Warnitchai’s scholarly work is well-recognized, with numerous publications and citations in the field of structural engineering. Dr. Panuwatwanich is Associate Professor in Civil Engineering and Director of Sirindhorn International Institute of Technology (SIIT), Thammasat University, Thailand. Prior to joining SIIT, he served as Senior Lecturer and Program Director at the School of Engineering and Built Environment, Griffith University, Australia. He obtained his Ph.D. from Griffith University, Australia. His research interests include engineering and construction management, with a specific focus on the applications of digital technology in construction, safety and innovation management, as well as sustainable construction.Dr. Tanapornraweekit is Associate Professor in Civil Engineering at Sirindhorn International Institute of Technology (SIIT), Thammasat University, Thailand. He obtained his Ph.D. from the University of Melbourne. His research focuses on the analysis and design of structures utilizing special concrete, including expansive, fiber-reinforced, and 3D-printed concrete, as well as the performance of concrete structures under extreme loads such as earthquakes and blasts.
