T/CI 311-2024 Method for evaluating fatigue performance of welding accessories structure of high strength steel tower of wind turbine unit
Basic Information
Scope
This document describes the evaluation method for the structural fatigue performance of welded accessories on high-strength steel towers of wind turbines. This document is applicable to the determination of the fatigue design values of welded accessories on land and offshore wind turbine towers, as well as the selection and comparison of structural steel materials. The selection and comparison of low-grade structural steel refer to its use. This document is also applicable to the evaluation of the structural fatigue performance of welded accessories during the material selection, supplier qualification review, or bidding stages, providing an important reference for owners and designers in selecting structural steel materials, and serving as an important basis for assessing the comprehensive capabilities of material suppliers.
