【摘要】 基于非线性内插法提出了求解冰振反应谱的一系列数值连锁递推格式,并利用该方法以及常用的线性内插法,对两条实际冰压力时程曲线进行了冰振反应谱的数值计算和分析。结果表明:基于非线性内插法得到的各冰振反应谱值一般稍大于线性内插法所得结果,加速度反应谱放大系数的最大误差在误差控制范围之内,可以满足精度要求,能在一定程度上简化计算。更多还原

【Abstract】 In this paper,the successive computation formulas of ice response spectrum are derived and deduced based on the assumption of nonlinear interpolation method.With the new way and linear interpolation method,the ice response spectrum was studied by two true different ice temporal curve.The results indicate that the ice spectra values obtained by the new method are a litter greater than the called precision method.And the error of the acceleration response spectra amplification coefficient is in tolerance variation.Therefore,this ice response spectra method presented can meet the request of precision.And with the new method,the calculation process can be simplied.更多还原
