| 摘 要： | 文章以呼和浩特市区钢筋混凝土建筑物为研究对象, 实施常时微动观测，分析了建筑物的振动特性，以及通过把呼和浩特市与其他地区的观测数据进行比较研究，初步探索了钢筋混凝土建筑物振动特性的地域差异,并得出如下结论: ⑴建筑物的第一次共振周期与楼层数或高度存在正相关关系，而楼层相同时则与建筑年代呈反相关关系，且大多数建筑物具有短轴方向的共振周期与长轴方向相同或较之偏大等特征。⑵大多数建筑物与地基间有着一定的相互作用。⑶同样建筑比较而言，福冈市的建筑物共振周期最小，乌兰巴托市最大，呼和浩特市和台中市的建筑物共振周期因长、短轴方向差异而大小不同。 |

| Abstract: | This paper analyzed the vibrate property of reinforced concrete buildings of Hohhot city with microtremor measurement , then compared them with the observation data of other regions and preliminarily studied the regional differences. And the following onclusions are drawn: (1) The first time resonance cycle is positively correlated with the floor number or height, but negatively related with the ages of building when floor No. is the same, moreover, short axis resonance cycle of most buildings is equal or larger than long axis resonance cycle.(2) Most buildings have some interactions with their foundation. (3) Comparatively analysis shows that Fukuoka city’s construction resonance cycle is maximum and Ulaanbaatar’s is minimum, Hohhot city and Taizhong city’s are different because of different construction directions. |
