滑移增大结构曲率，降低构件刚度，增加附加弯矩，从而引起挠度增大。
The slip displacement increases the curvature, reduces the stiffness, increases the additional moment and consequently leads the increase of deflection.
我国钢筋混凝土结构设计规范(TJ10—74)中未列出偏心受压构件刚度和裂缝的计算方法。
In our national Design Code of Reinforced Concrete Structures TJ10-74, there are no recommended methods for computing stiffness and crack of eccentrically loaded members.
然后测试其阻尼性能，结果表明嵌入较薄阻尼层会在构件刚度改变不大的情况下增大试样的阻尼。
Finally, the damping characteristics of them were tested. Test results showed that by adding a thin damping layer, the damping of structure was increased nearly without stiffness changed.
