GB/T 42600-2023Wind energy generation systems - Tower and foundation design requirements of wind turbines (English PDF)

1 Scope

This document establishes the structural integrity requirements and basic principles for assessing the support structures of onshore wind turbines, including foundations: fan

The scope includes general or site-specific geotechnical evaluation of the soil, flanges and connection systems to wind turbine nacelle components (including

The strength calculation of bearing connection) shall be designed and recorded according to this document or IEC 61400-1: The scope also includes all possible influences during the whole life cycle

Links that affect structural integrity, such as assembly and maintenance:

The evaluation load data is obtained according to IEC 61400-1 or IEC 61400-2, and takes into account the implied reliability level and local safety of the load coefficient:
