摘要
为了解决地震激励不确定性的描述问题及其响应的求解 ,提出了反应谱参量双界限和强度参量双界限 2个凸集模型 ,并结合工程实例 ,将该 2个模型的计算结果与其他模型的结果进行了比较 ,提出决定凸集模型合理性和实用性的关键在于 ,模型能否表达出地面运动强度的合理取值范围 .研究结果表明 :这 2个双界限模型 ,不仅模型参数的客观物理意义明确、概念清晰 ,并且能与现行常规方法有机地结合 .
The two response spectrum parameters and the two strength parameters of bounded convex model are presented for describing the uncertainty of horizontal seismic excitation and evaluating the structural respense. For a real engineering instance, the calculated results of these models are compared with those obtained by other models .The key is whether these models could determine the range of seismic intensity.This work indicates that the two parameters bounded convex models have clear physical meaning and sound concept.They can combine with existing routine seismic analysis.
