The response will raise, while the stiffnessofstructure will reduce, when increasing the span of structure;
增大膜弹性模量和结构矢跨比，结构响应的变化不明显。

It is thus possible to control the movement of a mass damper or adjust the stiffnessof a building's structure using relatively little power.
于是，这就有可能控制一个质量阻尼器的移动或相对地利用低功率来调整建筑物结构的硬度。

Calculation results show that the strength and stiffnessof the body structure have met the design requirements. However it is necessary to make further optimization for the original design.
