Abstract

With the help of probabilistic modeling, the issues related to the assessment of the robustness of structural systems made of prefabricated and monolithic reinforced concrete in an accidental design situation are considered. The paper considers the concept of analyzing the reliability of structural systems and differentiating risks in accidental design situations. The existing probabilistic models of the basic variables included in the functions of loads and resistances are analyzed. Statistical parameters of the uncertainty of the resistance model are obtained and integrated in the form of a basic variable with probability modeling. Probabilistic modeling of structural systems made of precast and monolithic reinforced concrete, designed according to the current standards of the Republic of Belarus, was carried out using the Monte Carlo method. The functions of the limiting state of the structural system in an accidental design situation with the sudden removal of the central column of the first floor are determined. As a result, values of failure probabilities and corresponding reliability indices were obtained for the considered constructive systems.
评估预制和整体钢筋混凝土结构体系鲁棒性的概率方法
在概率模型的帮助下,考虑了预制和整体钢筋混凝土结构系统在意外设计情况下的鲁棒性评估问题。本文提出了结构体系可靠性分析和事故设计风险鉴别的概念。分析了荷载和阻力函数中包含的基本变量的现有概率模型。得到了电阻模型不确定性的统计参数,并以基本变量的形式进行了概率建模。根据白俄罗斯共和国现行标准设计的预制和整体钢筋混凝土结构系统的概率建模使用蒙特卡罗方法进行。确定了在一层中心柱突然拆除的意外设计情况下结构体系极限状态的功能。得到了所考虑的构造系统的失效概率值和相应的可靠度指标。
