Design of Prestressed Girder Bridges Using High Performance Concrete An Optimization Approach
[摘要]

The objective of this paper is to assess the potential economic benefits from the use of high performance concrete (HPC) for continuous precast prestressed l-girder highway bridges. Unlike the traditional  approach of trial and error, this approach uses mathematical optimization techniques to provide systematic procedures for obtaining optima l designs. The analytical results illustrate the cost effectiveness  of HPC for bridge girders. Several practical advantages come from the use of HPC. Among the benefits is that because of increased girder capacity, the increased cost of HPC is fully offset by the reduced  number of girders.
