Results are fully compliant with British and European standards for structural design.
The recent generation of polyolefin-based macro-synthetic fibres have shown to meet the requirements of the standards for structural use.
International safety and design standards for structural performance analysis require full-scale testing of each wind turbine blade prototype and of blades that have undergone major design changes.
With regard to the structural analysis results, it can be said that the original design of the structure based on geometrical principles satisfy the reliability conditions defined by current European standards for structural design.
These different conceptual models for the structure require different criteria of failure, and the lack of attention to system analysis in standards for structural design has hidden the mismatches and incompatibilities between assumptions about the system behavior and the member behavior.
And the damage is often greatest in hurricane-prone parts of the country, such as Mississippi and Louisiana, where building standards for structural integrity are lower.
The regulations restrict where new coal ash impoundments and landfills can be built, mandates utilities to monitor storage facilities and repair leaks, and forces the closure of impoundments that don't meet standards for structural integrity.
