Horizontal wind loading is typically distributed into a lateral load resisting system through metal roof and floor deck.  That said, a wind load of 20 psf is applied to a two-story building face, each story being 12' in height, and the building being 100' in width.  What is the factored load that that is transferred via roof and floor deck that is applied to the roof and second story wind towers perpendicular to the wind loading?  Employ the concept of tributary area (but horizontally rather than vertically).

A timber prop of 120 mm diameter rests on a concrete plinth as shown. The plinth is 50 mm thick. If the shearing stress in the plinth is 13.9 MPa. Determine the axial load applied on top.

Wind can produce very high drag loads on high-rise bulidings. Since calculating the áow around a buildingis quite diffcult, you decide to perform an experiment to find the drag on the nearly completed Mirabellabuilding at Univesity Drive and Myrtle Avenue in Tempe. The building is 250 ft tall and approximately 210ft wide (at its widest part)   A) determine the drag on the Mirabella building for a sustained wind speed of 40 mph. Supposethat the temperature remains the same both inside and outside of the wind tunnel test section. If theatmospheric pressure is 100 kPa, what would the pressure have to be inside the tunnel test section tomaintain dynamic similarity between the model and the full-scale building? (You may assume that thetunnel is operating at maximum speed.
