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). 5,400 lbs and 15,400 lbs respectively 7,500 lbs and 17,500 lbs respectively 9,600 lbs and 19,600 lbs respectively 11,400 lbs and 21,400 lbs respectively

A cylindrical wood covered with steel is the cross-section of the post of a signage as shown. The steel signage has a thickness of 20 mm with a 1.5 m width by 1 m height dimensions and has a density of 7500 kg/m. During storm, the wind strike the signage a pressure of 0.9 kPa.

Problem #2: A flat roof is subject to the following uniformly distributed loads: a dead load of 21 psf (pounds per square foot of roof surface), a roof live load of 12 psf, a snow load of 13.5 psf, and a wind load of 22 psf upward. (Although the wind itself is in a horizontal direction, the force that it exerts on this roof is upward. It will be upward regardless of wind direction. The dead, live, and snow loads are gravity loads and act downward.) If load and resistance factor design is used, compute the factored load (ZyQ) in pounds per square foot.

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.

There are 5 load combinations below: Combination 1: 1.4DCombination 2: 1.2D+1.6L+0.5(Lr or S or R)Combination 3: 1.2D+1.6(Lr or S or R) +(0.5L or 0.5W)Combination 4: 1.2D+1.0W+0.5(Lr or S or R)Combination 5: 0.9D+1.0W How to deal with the wind load? If the wind load W=-22 psf, then the result of combination 5 will be -3.1 psf, which is negative. And the tensile strength of materials and…
