 All the prototype pile bents analyzed were plotted with the steel reinforced

prestressed pile bent for comparison (Figs. 7-10 through 7-15). The following notation

was used when referred to the prototype pile bents analyzed:

* Cast in place carbon prototype (CPCP)

* Cast in place glass prototype (CPGP)

* Spun cast carbon prototype (SCCP)

* Spun cast glass prototype (SCGP)

* Pre-cast prestressed carbon prototype (PCPCP)

* Pre-cast prestressed glass prototype (PCPGP)
