ERROR ANALYSIS OF SEISMIC HAZARD EVALUATION FOR BUILDINGS
-
摘要: 本文概述了引起震害损失评定误差的主要因素。通过实际震害评定资料,定量分析了震害损失评估中各因素形成误差数值的大小。采用以采样平均相对误差或采样均方误差及损失值相对误差来评估震害评定质量的方法,并通过分析给出综合衡量评定精度的量化指标,对震害经济损失评定准确度进行评估。Abstract: The main factors that cause the error in seismic hazard evaluation are discussed in this paper.The value of error made by each factor is obtained by the quantitative analysis of seismic hazard evaluation data.The quantitative index of comprehensive evaluation is given by analyzing the mean relative error of sampling, the mean square error of sampling and the relative error of loss valuve, and it is used to appraise the accuracy of seismic hazard evaluation.
