the girder and pier systems of a simple stringer-type bridge. The main objectives were to
identify the structural and economic benefits of utilizing concrete with a compressive strength
between 6,000 and 12,000 psi in these types of structural elements. This was to be
accomplished by first establishing the range of application for various girder and pier
designs in terms of their span length and axial load capacity, respectively. Then the cost …

OBJECTIVE
The primary focus of this investigation was the use of highstrength concrete in the girder and pier systems of a simple stringer-type bridge. The main objectives were to identify the structural and economic benefits of utilizing concrete with a compressive strength between 6,000 and 12,000 psi in these types of structural elements. This was to be accomplished by first establishing the range of application for various girder and pier designs in terms of their span length and axial load capacity, respectively. Then the cost-effectiveness of selected designs was evaluated by comparing their cost of construction.
