PCI BRIDGE DESIGN MANUAL (EXAMPLES DEVELOPMENT)

The scope of this work by SDR involved developing 10 bridge design examples to be included in the widely distributed PCI Bridge Design manual. The bridge types included prestressed concrete bulb-T, box beam, U-beam, double-T, and precast concrete stay-in-place deck panel system. The design was based on the latest AASHTO LRFD Specifications, which included refined calculation methods for several elements, such as prestressed loss and shear analysis. The work included using bridge analysis software, performing hand calculations and cross checking the results to confirm accuracy, and reviewing the latest AASHTO code.
