| Description |
This is a Joint Industry Project
(JIP), to:
- study the axial load-deformation response of patch-corroded steel tubular
members and to evaluate the effects of member diameter-to- thickness ratio,
corrosion profile, and load history has on member behavior;
- develop, evaluate, and calibrate analytical models and computational
methods based on the experimental results for prediction (change to)
predicting the response of corroded steel tubular members;
- determine the low-cycle and high-cycle fatigue resistance of machined and
naturally corroded tubular members;
- develop repair methodologies using advanced fiber composite material; and
- demonstrate the performance of the repair under monotonic loading,
low-cycle plastic loading such as in a severe storm or an earthquake.
|
| Progress |
The project is complete.
Analytical models developed at Lehigh have been fairly successful in
predicting the capacity of the corroded members tested. The results were
presented at the Corrosion Workshop in February 1999. |
