This paper presents a new simplified calculating method for concrete stnc-ture desing code to determinc the area of longitudinal bars in cempressive membersioad. ed with small eccentricities.Based on the tests,the expression of constant moment of resultant force D with respect lo. point As in the comprcssivc region of concrete members with small eccentricity in code (TJ10-74) is revised and a calculating method for the-longitudinal bars is presented in this paper. At the same timc,somc examples and charts are given,It indicates that there is a certain precision comparing with the accurate rcsults.Apparently this method is simpler and more convenient.
