| 摘 要： | 以都江堰某筒-柱支承式钢筋混凝土圆形筒仓结构为例，对简-柱支承式混凝土筒仓动力特性进行分析。研究表明：筒-柱支承式筒仓的底部筒-柱结构的开口削弱程度介于柱承式和筒承式之间，其侧移刚度与动力特性也介于二者之间，在频率较低时其运动状态体现为平动为主，达到一定频率时体现为扭转为主。研究结果可作为筒一柱支承式混凝土简仓动力分析与工程实际应用的参考和借鉴。

| Abstract: | The tube column supporting type reinforced concrete circular silo structure in Dujiangyan is taken as an example for the analysis of dynamic characteristics of tube-column supporting type concrete silos. The research indicates that the silo supported by co- umns-cylinder is weakened, and the weakening degree is between that of the silo supported by columns and silo supported by cylinder. Therefore, its stiffness and dynamic characteristics are between that of them. And its movement state is mainly horizontal when the natu- ral frequency is lower while its movement state is mainly twisting when the natural frequency is higher. The conclusion can be used as a reference for seismic response analysis and application in engineering. |
