This book delves deeply into the innovative application of BIM technology in the structural design of construction projects, as well as the cutting-edge theories of structural design approaches and robust design methods. From the fundamental theories of BIM technology to its practical application in structural modeling, collaborative design, and collision detection, and further to a comprehensive analysis of how BIM enhances design efficiency and evaluation, it showcases the intelligent trend of modern architectural design. Meanwhile, this work systematically introduces the theory of structural reliability, the application of design value method, and the analysis of combination value coefficients, providing a solid theoretical foundation for engineers. In response to the robustness requirements of engineering structural design, this work elaborates in detail on the robust design methods considering parameter uncertainties, and supplements it with practical cases of structural design for building renovation projects, offering valuable references for fields such as building renovation and reinforcement, and structural optimization design.
