Through the academic analysis,when design the shear-wall adopting the designing formula about shear-wall's normal section eccentric stressed bearing capacity in the current code for tall building(《Technical specification for concrete structures of tall building》 JGJ3-2002),it is found that under the same axial power,the shear-wall with belly reinforcement's bending-resistance bearing capacity is less than that of the shear-wall without the belly reinforcement;in an another point of view,with a certain axial power and moment,if add the dos...
