The substantial difference lies in that guaranteed rate frequency method determines the rate artificially, but synthetic duration curve method has its intrinsic frequency.
其根本差别只在于保证率频率法是人为地确定频率，而综合历时曲线法本身固有一个频率。
By solving recurrence equation of stochastic finite element, the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame shear structure.
通过求解随机有限元的递推方程，得到框剪结构各层的地震动力响应均值和标准差历时曲线。
This very simple example illustrates how modeling the duration with a distribution curve as opposed to a static specific value can cause a radically different simulation result.
这里通过使用一个非常简单的示例说明了如何使用分布曲线建模持续时间，这与静态特定值不同，静态特定值会导致完全不同的模拟结果。
