The use of high strength steel has the potential to reduce the amount of steel used in bridges and thereby, facilitate a more sustainable construction. A survey of existing bridges built using high strength steel is presented in this paper with emphasis on the Swedish bridge stock. The survey aimed at identifying the steel grades that were used and where in the cross-section they have been used. A case study on the influence of fatigue shows that today’s regulations make it more difficult to use high strength steel in comparison to previous regulations.

含高强度钢的钢桥概述

高强度钢的使用有可能减少桥梁中使用的钢量，从而促进更可持续的建筑。本文介绍了对使用高强度钢建造的现有桥梁的调查，重点是瑞典桥梁库存。该调查旨在确定所使用的钢种以及在横截面中使用的钢种。一项关于疲劳影响的案例研究表明，与以前的法规相比，当今的法规使使用高强度钢变得更加困难。
