ABSTRACT

The development of Portland cement and concrete in the 19^th and 20^th centuries revolutionised the construction industry, and provided a means of achieving architectural and structural feats that were previously impossible. While reinforced concrete bridges provided a means of simultaneously spanning vast distances and carrying significant loads, the material was little understood and designs reflected this. As a result, many early reinforced concrete structures suffer from significant durability issues and there is a growing requirement for their maintenance and repair, but the extent of the issue is unclear. As such, this review of historic test data intends to provide insight into previous reinforced concrete bridge design in Scotland, compare their design to current engineering codes, and discuss the implications for maintaining and preserving these unique examples of architectural heritage.

摘要

19、20^{世纪硅酸盐}水泥和混凝土的发展几个世纪以来，建筑业发生了革命性的变化，并提供了一种实现以前不可能实现的建筑和结构壮举的手段。虽然钢筋混凝土桥梁提供了一种同时跨越很远距离并承载大量载荷的方法，但人们对这种材料知之甚少，设计反映了这一点。因此，许多早期的钢筋混凝土结构都存在严重的耐久性问题，对其维护和维修的需求不断增长，但问题的严重程度尚不清楚。因此，对历史测试数据的回顾旨在深入了解苏格兰以前的钢筋混凝土桥梁设计，将其设计与当前的工程规范进行比较，并讨论维护和保护这些独特的建筑遗产示例的意义。
