This book focuses on the structural behaviours of concrete-filled steel tubular (CFST) structures at low temperature that relates to the cold regions. Its main contents include the material mechanical properties of steel and concrete at low temperatures, the steel tube-concrete interfacial bonding behaviour at low temperatures, the axial and eccentric compression behaviours of steel tubular structures at low temperatures, the axial and eccentric compression behaviours of CFST structures at low temperatures, the flexural bending behaviours of steel tubular and CFST structures at low temperatures, and the seismic behaviours of CFST structures at low temperatures. Based on the construction requirements of polar and cold-region engineering, this book establishes the fundamental theories and design methods for concrete-filled steel tubular structures at low temperatures, and addresses the critical challenges in the analysis and design of CFST structures at these cold regions. This book can be used as a textbook for undergraduates and postgraduates majoring in Civil Engineering in institutions of higher education. It also serves as a reference for designers, constructors and researchers engaged in steel-concrete composite structure engineering.

Jia-Bao Yan, Ph.D, is a Professor at Department of Civil Engineering, Tianjin University, P.R. China.
