The effect of corrosion on the natural frequency and modal damping of reinforced concrete beams

H. Abdul Razak, +1 more
- 01 Sep 2001 - 
TL;DR: In this article, the effect of general corrosion on the modal parameters of reinforced concrete beams was studied and the results showed that the trend in measured natural frequencies was sensitive to the deterioration state of the beams and the changes were inconsistent with the changes in natural frequencies, but a trend was observed which was rather mode dependent.

Frequently Asked Questions (3)
Q1. What is the purpose of the RC beam?

The RC beam is simply supported and subjected to flexural loading in order to simulate loading on actual RC structures such as bridge girders, beams and slabs. 

Roughness equipment is used on the tension surface to obtain a suitable face and to have as much friction as possible with the CFRP sheet. 

This is because the substrate must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loosely adhering particles.
