JIPKIC 结构设计原理 The principle of structure design S7.3 Vertical Eccentric Compression Bending Reinforced concrete compression members under eccentric loads in,it will have a vertical bending,which will produce lateral deflection.Because the impact of lateral deflection,the cross section is no longer the moment suffered,and become a N(eo+u) that is, l/2 Neo M=N(e+w)=N(eo+四 eo =nNeo eo Known as the additional momene) /2 The impact of the additional bending moment for different slenderness ratio of eccentric compression, damage type is also different.
