摘要: |
Glass fiber reinforced polymers (GFRPs) were selected and used to build the bridge deck for OFallon Park Bridge in Denver, Colorado. This report contains two parts. The first part is an in-house experimental study on the durability of the selected GFRPs, and the second part is an on-site loading test for the behavior of one GFRP panel of the bridge and a long-term monitoring study of the panel. The influential parameters for the durability of GFRPs were reviewed, including freeze-thaw cycles, moisture penetration, deicing chemicals, alkali and acid attacks, and ultraviolet light. Experimental plans were carefully designed for the in-house durability study and the on-site loading test, as well as for the long-term monitoring of the bridge panel. |
