Conclusion

Two separate studies on wind turbine have been conducted with and without shear webs, one of the

reinforcements against flexural loads. What has been found is that, with shear webs the displacement

appears to be much lesser than it would be otherwise. The study further requires analytical validation.

Percentage of difference is calculated as 10%, i.e. this much amount of displacement has been deduced by

configuring the model with and without shear webs.
