Abstract

A probabilistic framework for the expected damage estimation of RC half-joints under traffic load is proposed. Taking into account the uncertainties in geometrical features and mechanical properties, and introducing a probabilistic model for the traffic load, the proposed procedure links the structural response of RC half-joints, described by fragility curves, to financial consequences, according to the Loss-Based Design (LBD). In addition to the reliability of RC Gerber bridges, as impacted by the structural response of RC half-joints, the procedure allows to identify proper strengthening interventions focusing on cost-effectiveness and efficiency. The improved level of information regarding the structural performance of bridges can become the basis for more rational decision making as part of risk management strategies. The procedure is applied to the RC Gerber bridge “Annone” (Italy), which is investigated, as case study, in the as-built configuration and assuming a strengthening intervention.

交通荷载作用下钢筋混凝土半连接件的预期损伤评估
本文提出了一个用于估算交通荷载下钢筋混凝土半连接件预期损坏的概率框架。考虑到几何特征和机械性能的不确定性,并引入交通荷载的概率模型,根据基于损失的设计(LBD),所提出的程序将脆性曲线描述的 RC 半接面结构响应与经济后果联系起来。除了受 RC 半接缝结构响应影响的 RC 格柏桥的可靠性外,该程序还能确定适当的加固干预措施,重点关注成本效益和效率。桥梁结构性能信息水平的提高可作为风险管理策略的一部分,成为更合理决策的基础。该程序适用于 RC 格柏桥 "Annone"(意大利),作为案例研究,该桥是在竣工配置和假定加固干预的情况下进行调查的。

期刊介绍: This journal provides a forum for scholarly work dealing primarily with probabilistic and statistical approaches to contemporary solid/structural and fluid mechanics problems encountered in diverse technical disciplines such as aerospace, civil, marine, mechanical, and nuclear engineering. The journal aims to maintain a healthy balance between general solution techniques and problem-specific results, encouraging a fruitful exchange of ideas among disparate engineering specialities.
