1 Scope

GB/T 42600-2023 sets the design requirements for wind turbine towers and foundations. The tower is the largest and heaviest thing in a wind farm and the part most often bought separately from the machine on top of it, which is where the difficulty lies: the loads come from the turbine manufacturer's simulation, and the tower designer has to receive them in a form that can be used and interpreted correctly, or the structure is designed against the wrong spectrum. Fatigue governs, not ultimate strength, and the welds and bolted flanges are where it shows. The standard sets the design criteria including the materials, the loads and the load data and interface reporting requirements, the general structural design requirements and the delivery documents, then the steel tower with its ultimate strength analysis including openings, its stability and its fatigue, and the corresponding requirements for concrete towers and for the foundations. It took effect on 23 May 2023.

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:
