The outside noise of the stones is perceived inside, it resonate in the box-shaped modules and it's amplified by the metal structure itself.
石头的外部噪声会被内部感知，它在盒形模块中传播并且音量会因为本身的金属结构而扩增。

The seismic capacity of the box-shaped joint in the reinforced concrete mega-frame structure system is studied, and the finite element analysis is done with ANSYS .
本文对钢筋混凝土巨型框架结构箱形节点抗震性能进行了试验研究及ANSYS程序有限元分析。
