钢筋沥青隔震层计算减震系数修正方法探讨
|
摘要
在振动台模拟试验的基础上,研究了减震系数的修正方法。对有沥青油膏和无沥青油膏两种情况减震系数的试验值和理论值进行了对比分析。还通过对减震钢筋偏斜角度的概率分布分析,对如何修正计算减震系数进行了探讨,提出了一种利用数理统计理论对其合理有效地进行修正的方法。
Based on shaking table test,the correction method of seismic reduction factor is researched.The test values of isolation layer with asphalt and without asphalt are conpared with the theoretical values.Also,through the analysis of skew angle probability distribution of the isolation layer steel bar,the method of correcting calculation of seismic reduction factor is discussed,and a kind of method which is reasonable and effective is put forward by using the theory of mathematical statistics.
