This research project will continue efforts in the area of probabilistic analysis of structural loads and will attempt to overcome some of the limitations of the current methods for load combination analysis. A major objective of the project is the development of a simple and general approach for approximating the largest value distribution and other descriptors of individual load effects and their combinations. It is planned to: 1) examine novel load models (translation processes) that can be obtained from Gaussian processes by nonlinear transformations, 2) develop techniques for the analysis of linear and nonlinear combinations of independent or dependent translation processes, and 3) calibrate the proposed models to common structural loads based on statistical observations of these loads and to determine probabilistic characteristics of their combined effect.

本研究项目将继续在结构荷载的概率分析领域进行努力，并将尝试克服当前荷载组合分析方法的一些局限性。该项目的一个主要目标是发展一种简单而通用的方法，以近似最大值分布和个别负载影响及其组合的其他描述符。计划：1)检查可以通过非线性变换从高斯过程获得的新型负载模型（翻译过程），2)开发独立或相关翻译过程的线性和非线性组合分析技术，3)基于这些荷载的统计观测，将所提出的模型校准为常见的结构荷载，并确定其联合效应的概率特征。
