Document Summary

Structural design - methodical investigation of the stability, strength and rigidity of structure. Structural analysis and design - produce a structure capable of resisting all applied loads without failure during its intended life. Step 1: identify possible sources of loads on the structure. Wind load, weight of turbine and internal machines, snow, earthquake, blast, wave, etc. Converting wind speed to wind pressure (metric system) Q = wind pressure (pa=) (us system) Wind force = wind pressure x area exposed to wind. Weight, strength, price, rigidity (toughness), flexibility, availability, durability, ductility, etc. E = modulus of elasticity, young"s modulus = ksi. Axis loading, lateral load, bending moment, twisting moment. = normal stress due to bending (ksi, mpa) C = distance from center of section to the edge. I = second moment of inertia () Moment = distance (vector) x force (vector) W = distributed load (lb/ft) = wind pressure x width of blade.
