Several steel bridges in Egypt were built during the late nineteenth to early twentieth centuries. At this time, riveted construction was the method used for building up members and for the connection of one member to another. In this paper, field measurements were performed to find the actual dimension of an existing old riveted steel bridge (El-Ministerly Bridge, Egypt). The inspection of the steel bridge did not find any clear cracks. Finite element models were created to predict the response of the steel bridge. The finite element model was used to identify the location of the stress concentration. A static field test was performed using a 49-ton truck to evaluate actual strain measurements in different locations over the bridge. The strain measurement was used to validate the finite element model while was able to predict the experimental data closely. As an application of the use of the finite element model, evaluate the bridge was executed using AASHTO standards, Egyptian code (ECP) and S–N curves from the literature. It was observed that all stress ranges for this bridge were less than the ECP limits (F_sr) and the estimated remaining fatigue life is about 11 years if it is environmentally protected.

有利钢桥的现场试验与数值模拟

在19世纪末至20世纪初，埃及建造了数座钢桥。这时，铆接构造是用于建立构件以及将一个构件连接到另一个构件的方法。在本文中，进行了现场测量，以找到现有旧铆接钢桥（埃及El-Ministerly桥）的实际尺寸。对钢桥的检查没有发现明显的裂缝。创建了有限元模型来预测钢桥的响应。有限元模型用于确定应力集中的位置。使用49吨卡车进行了静态测试，以评估桥上不同位置的实际应变测量结果。应变测量用于验证有限元模型，同时能够精确预测实验数据。作为使用有限元模型的一种应用，使用AASHTO标准，埃及规范（ECP）和文献中的S–N曲线对桥梁进行评估。观察到，该桥的所有应力范围均小于ECP极限（F _sr），并且如果受到环境保护，估计的剩余疲劳寿命约为11年。
