JPKIC 结构设计原理 The principle of structure design S7.2.3 Eccentric structure of the correlation curve 1)When the (M-N)on the curve or curve aba falls outside the occurrence of damage to the cross section. 2) e-M-1ge,bigeer,emore bieger. 3)Three feature points(a、b、c) 1) When the on the curve or curve falls outside the occurrence of damage to the cross section. (M − N) abd tg, N 2) e = M =  bigger， e more bigger。 3) Three feature points（a、b、c） §7.2.3 Eccentric structure of the correlation curve
