本文基于118个地面强震记录水平面内每一方向的峰速度、峰加速度和阻尼比分别为0、2％、5％、10％、20％的绝对加速度反应谱数据,用每个记录的平均峰速度和平均峰加速度分别标定了相应的五种阻尼比的平均设计反应谱,统计了其动力系数的标准差,其结果可供重大工程抗震设计和地震地面运动小区划工作参考使用。在此基础上,利用作者建议的同时考虑房屋层数和场地类别时由地震烈度转换的地面峰加速度和峰速度得到平均设计反应谱,给出了相应的标准差,该结果可供一般工程抗震设计参考使用。
This paper uses absolute acceleration response spectrum data of 0, 2%, 5%, 10%, and 20% of peak velocity, peak acceleration, and damping ratio in each direction in the horizontal surface record of 118 ground motion records, using the average of each record. The average design response spectra of the corresponding five kinds of damping ratios were calibrated for the peak speed and the average peak acceleration, and the standard deviation of the dynamic coefficients was statistically calculated. The results can be used as a reference for the major engineering seismic design and seismic ground motion community planning work. On this basis, the average design response spectrum obtained from the ground peak accelerations and peak velocities converted by the seismic intensity at the same time as the author's proposal considers both the number of floors and site categories of the house, and the corresponding standard deviation is given. This result can be used for earthquake resistance of general engineering projects. Design reference use.
