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.
大量试验结果表明，在罕遇地震作用下节点核心区内梁纵筋的粘结滑移是钢筋混凝土结构的一种比较常见的局部非线性反应。
Many experimental results indicates, beam bar slippage within joints is a frequent local nonlinear response of reinforced concrete structures under the rare earthquakes.
以钢管的宽厚比、混凝土强度、钢管高宽比及试件有无纵筋为主要参数进行了20个方钢管约束钢筋高强混凝土轴压短柱的试验研究。
The ductility of the tested columns decrease with the increase of concrete strength and width-to-thickness ratio. (2) 20 square steel tubed RC columns were tested under static axial compression.
