| 摘 要： | 传统结构分析中主要研究产生结构破坏的低频振动,由于低频波波长相对于建筑结构的尺寸较大,振动的衰减主要与建筑结构采用的材料有关,而没有必要考虑波在结构内部,沿不同形式构件传播产生的差异.而生活噪音的频率集中在500Hz～2000 Hz左右,其波长相对于建筑结构较小,所以此差异必须加以考虑.以三种常用的建筑结构形式为研究对...

| Abstract: | Traditional structural analysis focuses mainly on low frequency vibrations.As the wave length for low frequency waves is much bigger than the size of the structure,vibration decays mainly with time,which is caused by material damping,and the wave transmission within the structure is negligible.As the frequency of daily noise is mainly from 500Hz to 2000Hz,corresponding wave length is relatively short compared to the size of the structure.Therefore,it is necessary to consider the transmission decay of noise ... |
