Loading Requirements
Step 1: preliminary calculations
for carbon and exterior expsoure
Determine the stress block parameters:
Point A: Axial Loading Only
Point D:: Axial Loading with Minimum Eccentricity
Point B: Concrets strain = 0.003 and farthest steel yielded
Point C: Steel Yeilds and Concrete Crushes Simultaneously
Point E: Fixed Value of Eccentricity
use:
Point F: Pure Flexure
