Chapter 2 Design for Shear

Each vertical leg of a stirrup has a tension capacity equal to its yield strength, and the most common stirrup has 2 vertical legs. The shear capacity of vertical stirrups is the tension strength of one stirrup times the number of stirrups that interrupt potential cracks on a 45degree angle from the tension steel. Thus, Vs = Avfyd/s.

Vertical Axis Wind Turbine Evaluation and Design

turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and wide use. Figure shows a diagram of these two types of systems.
