利用典型的加速度图和速度图,得到了强地面运动和反应谱各参数之间的相关关系。考虑了以下几种关系:地震动各分量振幅间的关系;各分量振动周期间的关系;地面振动参数及其反应谱相应参数间的关系;各分量反应谱对数宽度之间的关系;加速度、速度、位移脉冲宽度间的关系。本文揭示了NIS采用的建筑规范和某些实际关系的不一致性,还估计了动力系数对阻尼的依赖性。从这些估计中可以得知,利用反应谱得到的地震烈度的精度与使用振幅峰值得到的精度相一致。这些结果可用于解决与地震作用和建筑物特性有关的空间问题。
Using typical acceleration maps and velocity maps, correlations between parameters of strong ground motion and response spectra were obtained. The following relationships are considered: the relationship between the amplitudes of the components of the ground motion; the relationship between the vibration period of each component; the relationship between the ground vibration parameters and the corresponding parameters of the response spectrum; the relationship between the log widths of the response spectra of the components; , speed, displacement pulse width relationship. This article reveals the inconsistency between the building codes used by NIS and certain practical relationships, and also estimates the dependence of dynamic coefficients on damping. From these estimates, it can be seen that the accuracy of the seismic intensity obtained from the response spectra is consistent with the accuracy obtained using the amplitude peaks. These results can be used to solve the spatial issues related to earthquake action and building characteristics.
