合理化橋梁
In the construction industry, minimizing the usage of material resources and energy to preserve the global and regional environments is required to reduce the environmental impact. The longevity of civil structures is one of the useful methods to reduce the lifecycle cost (LCC) and lifecycle CO2 emission (LCCO2) during the construction, maintenance and replacement stages of structures. In this study, the lifecycle analysis of newly developed bridges, named the minimized girder, the rationalized box-girder and the rationalized truss bridges in Japan, was performed. The lifecycle analysis of the conventional bridges, I-girder, box-girder and truss bridges, were also performed and compared with those of the newly developed bridges. It was found from the analysis that the newly developed types of the bridges have not only less total LCC but also less total LCCO2 than the corresponding conventional bridges. The characteristics of the LCC and LCCO2 during maintenance stage of the bridges were discussed.
