| Research Abstract |
The global warming environmental impact is most important problem all over the world. In this study, the volumes of steel of bridges are considered social resource, and the volume of steel is one of the parameter for analyses. The analytical methods are performed by Data Envelopment Analysis(DEA) and super DEA, also parameters are CO2 emissions of lifecycle and lifecycle cost are used as input data, life length and volume of steel are used as an output data.
In the present bridges system, when considering the social steel resource environmental impact of the all type of bridges are not larger deference occurred in DEA analyses. In the case of analyses are performed by using super DEA, high reliable ranking carried out for the environmental impact of bridges.
