Determine the external wind pressure on the roof of the rigid-gabled frame of a building for an essential disaster operation center shown in Fig. P2.14. The building is located in Kansas City, Missouri, where the terrain is representative of exposure C and the basic wind speed for risk category IV buildings is 120 mph. Assume the wind direction is normal to the ridge, as shown in the figure. Use Kd 50.85 for main wind-force resisting systems, and Ke =1
**do not solve this problem using the eqn F= Cs x W please use the example used in the textbook (image attached)** problem: A two-story hospital facility shown in Figure P2.24 is being designed in New York with a basic wind speed of 90 mph and wind exposure D. The importance factor I is 1.15 and K, = 1.0. Use the simplified procedure to determine the design wind load, base shear, and building overturning moment. (b) Use the equivalent lateral force procedure to determine the seismic base shear and overturning moment. The facility, with an average weight of 90 lb/ft? for both the floor and roof, is to be designed for the following seismic factors: Sds= 0.27 and Sd1= 0.06 reinforced concrete frames within our value of eight are to be used. The importance factor is 1.5. (C) do wind forces or seismic forces govern the strength design of the building?
The roof of rigid gabled frames 5 meters on centers has a slope of 30 degrees. If the wind velocity pressure in the area is 3.2KPa , Gust Effect Factor, Gt=0.85 and external pressure coefficient of 0.35 (pressure) and 0.42 (suction). Calculate the total amount of wind load in KPa on the windward side of the roof. Express your answer in 2 decimal places.
