抄録

The construction industry consumes a great deal of natural resources and energy in constructing, maintaining and demolishing their products such as buildings and bridges. These activities lead significant impacts on global and regional environments in addition to their economic expenses. In this research, the lifecycle cost (LCC) and lifecycle CO2 (LCCO2) emission of newly developed bridges, including the minimized girder, rationalized box-girder and rationalized truss bridges, are quantified and compared with those of the conventional I-girder, box-girder and truss bridges. It was found that the newly developed types of bridges have lower values in both LCC and LCCO2 than the corresponding conventional bridges do. The effects of span lengths on LCC and LCCO2 are studied for both conventional and rationalized bridges. The characteristics of LCC and LCCO2 are investigated over the lifecycle of a bridge including its construction, maintenance and replacement stages.
