Analysis of the whole life cycle cost of corrugated web steel box-concrete composite girder bridges
As a type of prefabricated structure bridge,the box concrete composite girder bridge with corrugated steel web has the characteristic of a novel structure,a short construction period,and light weight.Taking the box concrete composite girder bridge with corrugated steel web on the Jingzhong Expressway Airport Link in Gansu prov-ince as an example,the life cycle cost of the bridge was evaluated in detail herein by considering different discount ratios and finance and time values.The results show the discount ratio has a remarkable impact on the life cycle cost of box concrete composite girder bridge with corrugated steel web,and the higher the discount ratio is,the low-er the life cycle cost is whilst the rise in the discount ratio would increase the proportion of the cost in construction investment period to life cycle cost,but cause a reduction in the that of operation service period and demolition re-cycle period to life cycle cost.The conclusion of this paper can provide a reference for the investment decision and be conducive to scheme comparison of this type of bridge to a certain extent.
