This book offers a clear and comprehensive overview of both the theory and application of fundamental aspects of concrete-filled double steel tubes (CFDST). Many analysis and design applications are presented, which involve mechanical components and structural members often encountered in engineering practice. This monograph is written for practicing structural and civil engineers, students, and academic researchers who want to keep up to speed on the latest technologies for concrete-filled steel tube (CFST).

Discusses numerous exploratory tests to help readers understand concrete-filled twin steel tube structures Presents accurate and robust numerical study models for simulating structural behavior Addresses five types of connection design for engineering applications
