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.
A building's entrance canopy is constructed as a fixed slab attached to one of its longer sides. The slab has dimensions of 2.50 m x 6 m and a thickness of 225 mm. It is designed to bear various loads, including a uniform live load of 2000 Pa, a uniform dead load of 5000 Pa (excluding the weight of the slab itself), and a concentrated dead load of 5000 N per meter applied at the far end of the support. The design of the slab ensures that the main bars are oriented parallel to the shorter span. The specified design properties include a compressive strength (fc') of 21 MPa, a yield strength (fy) of 345 MPa, 16-mm-diameter main bars, 10-mm-diameter temperature bars, and a clear cover of 20 mm. The unit weight of the concrete is 23,544 N/m3.Find: 1. Determine the spacing of the main bars in mm
2. Determine the spacing of the temperature bars in mm
a building will have a sitting wall on the north side of the building to allow for seating during outdoor season. the wall will be 1.5 meter tall. what is the minimum width of the wall to ensure that it will not slide or overturning? the soil behind the wall is a sand with Gamma dry= 18.3 kN/m^3 , gamma buoyant =11.5 Kn/m^3 , gamma water= 9.81 kN/m^3 and phi= 36 degrees. the water table is 0.5 m below the ground surface. to enhance the aesthic value of the seating area, the architect has asked that the wall he made of granite ( gamma granite= 25 kN/m^3 .
