结构耐久性能是结构在外界环境及设计预期正常荷载共同作用下,在同样(或等效的)的建设和运营维护总成本(寿命周期总成本)下,在给定使用寿命期内,保持预期的安全性、适用性的能力。本文主要分析高速公路桥梁的安全性和耐久设计。
Structural durability is the result of a structure that is expected to maintain the expected (or total) life-cycle cost under the same (or equivalent) total cost of construction and operation and maintenance (total life-cycle cost) The safety, applicability of the ability. This article mainly analyzes the safety and durability design of expressway bridges.
