| 摘 要： | 基于3层普通抗震混凝土框架结构,采用能力谱法评估了矩形框架结构的抗震性能,从实验结果中获取能力曲线,并利用在地面特性条件下的各站记录的地震地面运动建立需求曲线。评估结果表明,3层混凝土框架可以抵抗地面条件为1和2的所有地震带A,B,C,D和E的地震荷载;对于地面条件3,混凝土框架在地震带A,B,C和D中的实验结果令人满意;对于地面条件4,混凝土框架只对地震带A和B有效。

| Abstract: | Based on the experimental results of a three-story ordinary seismic concrete frame, in this paper, we use the capability spectrum method to evaluate the seismic performance of a rectangular frame structure. We obtained the capacity curves from the experimental results, and established the demand curves using the seismic ground motions recorded by stations with different surface characteristics. The assessment results show that the three-story concrete frame can withstand seismic loads in all seismic zones (A, B, C, D, and E) with ground conditions 1 and 2. For ground condition 3, the experimental results of the concrete frame were satisfactory in seismic zones A, B, C, and D. For ground condition 4, the concrete frame was only valid for seismic zones A and B. |
