Maximum area of cross-section of longitudinal bars must not exceed 6% of the gross cross-section area of the column. Finding the effective cross-section area larger than this value from the table at right shows that a 14. The cross-sectional area, AVfi of the reinforcement per unit length(of the beam or girder. Three methods were mainly used in earlier studies to calculate the stress of a corroded steel bar from the measured force, which are based on the average reduced cross-sectional area [3, 5], the original cross-sectional area , and the smallest cross-sectional area of the bar, respectively. 8m long x 2. As we know, different countries have their own way to measure and record the reinforcing bar. Calculate the values of R m and R c using the nominal cross sectional area. On active roads or trails, conveyor belts, old snowmobile treads, and similar material (see Figure 7) can be used instead of soil to build water bars. 1 m wide, 1. due to local buckling parts of the cross-section are excluded from the cross-section area and section modulus (see fig.
