Abstract
Structural engineers have to pay close attention to the environmental cost component in their structural designs arising from people’s concern on global warming since structural framework contributes a lot to the total emissions of the building in the life cycle. This paper introduces the environmental cost index of embodied carbon as well as research and engineering applications to solve the problem that there is no effective method of calculating environmental cost. Structural engineers tend to ignore environmental effects of structures at most times in the actual design process. The comprehensive structural system selection method proposed by this paper which combines life cycle assessment method, ICE database and abatement model considers both economic and environmental costs that count for emission reduction cost. The method is applied to compare different largespan spatial structural systems in Changsha based on environmental cost. Conclusion is drawn that truss system is the best scheme when emission reduction cost is considered. This paper not only provides a reference for similar projects to compare different structural systems in the comprehensive perspectives of environment and economy but also provides a guide for structural engineers to contribute to a more sustainable built environment.
