JTG 2120-2020 in English

This standard provides a unified framework for the design of structural reliability in highway engineering projects. It outlines the fundamental principles and methodologies necessary to ensure the safety, serviceability, and durability of highway structures. The document defines key parameters and criteria for assessing the performance of engineering structures under various loading conditions and environmental influences. It also establishes guidelines for the application of probabilistic methods in the design process. The standard aims to harmonize design practices across different segments of the highway engineering industry. It includes provisions for the evaluation of material properties, load combinations, and safety factors. Additionally, it specifies the requirements for the analysis and design of structural components to meet specified performance levels.
