带混凝土筒大开间砖混结构灵活住宅体系的特点是，每个单元有一个钢筋混凝土楼梯筒，分户横墙与外纵墙均采用组合砖墙砌体。
The unique feature of the large bay flexible residential building is that:every unit itself consists of a reinforced concrete tube-stairway core body-with its repective composite wall with openings.
除剪力墙中的钢筋本文模型中其他纵筋采用LINK8单元模拟，该单元只传递轴力且没有体积。
LINK8 element is used to model the steel reinforce bar except in the wall. LINK8 can only transfer axial force and has no volume.
分析结果表明，如将普通纵筋的5%改配为碳纤维筋，在强地震荷载作用下桥墩残余位移以及最大曲率响应均小于普通钢筋混凝土桥墩。
The results showed that if 5% steel bars are substituted by carbon fiber bars, the residual deformation and maximum curvature decrease compared with the reinforced concrete pier.
