In the early 1950s, the first‐generation of precast prestressed bridges was built in Europe. The prestressing technology was still relatively new and bridges were sometimes executed questionably. The consequences of poor detailing and inadequate maintenance are shown as a practical example of a 59‐years old road precast bridge in Slovakia that recently reached a near collapse state. The behavior of the damaged prestressed precast structure was verified by the full‐scale load test. In the case of advanced corrosion of the tendons, it is often very difficult to accurately determine the actual resistance of a structure. The test results published in the paper may help to find a practical method for the assessment of similar aged existing prestressed bridges.

斯洛伐克第一代预制预应力桥梁的故障和损坏

1950年代初，第一代预制预应力桥在欧洲建造。预应力技术仍是相对较新的技术，有时桥梁的使用存在问题。细节不足和维护不充分的后果以斯洛伐克一个59岁的道路预制桥的实例为例，该桥梁最近达到了近乎坍塌的状态。受损的预应力预制结构的行为已通过满负荷测试进行了验证。在对钢筋束进行高级腐蚀的情况下，通常很难准确确定结构的实际阻力。论文中发表的测试结果可能有助于找到一种实用的方法来评估类似的已有老预应力桥梁。
