Session A5: Improving existing facilities

摘要

Test data were provided by the material supplier. In general these showed low reductions in material strength in the long term where the material was not subjected to continual loading. It should be noted that when stressed continually, the ultimate capacity of GFRP does reduce in time and a design would need to take this into account. In our situation the bars are only used to resist the higher peak loads during wave impact conditions, therefore the total duration of the higher loads is very short over the whole 50yr design life, or over an extended design life of up to 100 years.
