Abstract

An algorithm for the reliability and durability assessment of stay cables in bridges is presented in this study enabling their probability of failure and a safe working period to be determined under various loading scenarios. The algorithm was originally developed based on data collected from an extensive structural monitoring campaign of the biggest single-pylon concrete cable-stayed bridge in Poland and used to assess the durability of its suspension system. It was then modified to be suitable for the evaluation of stay-cables subjected to wind excitation and structural reliability of the suspension system in a real steel bridge where permanent plastic deformations occurred in the anchor zones of the stay cables. The algorithm takes into account analytical models describing the stay cables and their numerical finite element models (FEM). As such, it is a universal tool having a wide range of applications, also beyond stay cables often encountered in medium- and long-span bridges forming a critical part of the civil engineering infrastructure.

桥梁悬索的可靠性和耐久性评估

本研究提出了一种对桥梁中的斜拉索进行可靠性和耐久性评估的算法，该算法可在各种荷载情况下确定斜拉索的失效概率和安全工作期。该算法最初是根据对波兰最大的单塔混凝土斜拉桥进行的广泛结构监测活动中收集的数据开发的，用于评估其悬挂系统的耐久性。随后对其进行了修改，使其适用于评估受风激励的斜拉索，以及在斜拉索锚固区发生永久塑性变形的实际钢桥中悬挂系统的结构可靠性。该算法考虑了描述斜拉索的分析模型及其数值有限元模型（FEM）。因此，它是一种通用工具，具有广泛的应用范围，也不局限于构成土木工程基础设施重要组成部分的中跨和大跨桥梁中经常遇到的留置索。

期刊介绍： Archives of Civil and Mechanical Engineering (ACME) publishes both theoretical and experimental original research articles which explore or exploit new ideas and techniques in three main areas: structural engineering, mechanics of materials and materials science. The aim of the journal is to advance science related to structural engineering focusing on structures, machines and mechanical systems. The journal also promotes advancement in the area of mechanics of materials, by publishing most recent findings in elasticity, plasticity, rheology, fatigue and fracture mechanics. The third area the journal is concentrating on is materials science, with emphasis on metals, composites, etc., their structures and properties as well as methods of evaluation. In addition to research papers, the Editorial Board welcomes state-of-the-art reviews on specialized topics. All such articles have to be sent to the Editor-in-Chief before submission for pre-submission review process. Only articles approved by the Editor-in-Chief in pre-submission process can be submitted to the journal for further processing. Approval in pre-submission stage doesn''t guarantee acceptance for publication as all papers are subject to a regular referee procedure.
