本文介绍了上海地区几幢超高层建筑动力特性实测结果 ,这些建筑包括上海金茂大厦、上海森茂大厦、上海建设大厦、上海凯旋门大厦 ,其中部分建筑的实测结果与理论计算和模拟地震振动台试验结果进行了比较。实测结果表明 ,大部分超高层建筑的自振频率计算值与实测值接近 ,阻尼比一般在 0 0 1～ 0 0 4之间。规范提出的设计方法适用于结构形式简单、规则的建筑 ,对复杂结构宜进行模拟地震振动台试验
This paper introduces the measured results of dynamical characteristics of several super tall buildings in Shanghai. These buildings include Shanghai Jinmao Tower, Shanghai Senmao Tower, Shanghai Construction Building and Shanghai Arc de Triomphe Tower. The measured results, theoretical calculations and simulated shaking table tests The results were compared. The measured results show that the calculated values of natural frequency of most super tall buildings are close to the measured values, and the damping ratio is generally between 0 0 1 ~ 0 0 4. The design method proposed in the norms is applicable to buildings with simple and regular structures, and it is appropriate to simulate the seismic shaking table test for complex structures
