| 摘 要： | 研究约束屈曲支撑对双层球面网壳减震效果的主要影响参数和影响规律.通过考虑约束屈曲支撑不同的设置方式、位置和数量,以及不同的网壳矢跨比、跨度,进行相关的减震参数分析.结果表明,替换方式比附加方式的减震效果显著;替换杆件的位置对减震效果有较大的影响;约束屈曲支撑设置的数量应综合考虑;网壳的矢跨比和跨度也是影响减震效果的关键因素.

| Abstract: | The main influencing parameters and patterns of bending-restrictive buckling support(BRBS) on the effect of vibration reduction of double-layer reticulated spherical shell were investigated.correlative analysis of vibration reduction parameters was conducted by means of changing the setting manner,position,and numer of the BRBS,and the hight vector-span ratio and the span itself of the shell.The result showed that the vibration reduction effect of substitution manner was more obvious than appending one,the ... |
