In the past 30 years, significant progress has been made in the field of civil engineering and infrastructure construction in China, greatly supporting the continuous development of the economy. While China's economy steps into the "new normal" phase, the development of civil engineering shows some new features and the developments of fundamental theories and advanced technologies attract more and more attention. Nonlinear analysis of structures, one of the essential problems in civil engineering, has been concerned by more and more researchers and engineers. For constitutive modeling of engineering materials, the damage model plays an important role where structural damage and failure are considered. In this paper, the historical development of damage model for quasi-brittle materials is briefly reviewed. Then V&V of the damage model is described and its applications to civil engineering are presented by case studies. Finally, an application of the theory to bio-engineering is shown with a case. In the near future, the transformation and upgrading of traditional civil engineering will be promoted by the coupling between its fundamental research and engineering application.
