Question

Please answer it step by step and I will give thumbs up

(use wind pressure on the main wind force resisting system MWFRS equation)

The final answers should be Zone A = 40.9 psf, Zone E = -49.1 psf

P2.23 A convenience store is to be built in New Orleans, Louisiana (latitude 29.97°, longitude-90.06°) in a location that could be classified as an exposure wind pressures for the MWFRS of the building for the wind direction shown in the accompanying figure. Provide a sketch of the wind pressure zones similar to what is presented in Example 2.8. (Ans: zone A- 40.9 psf, zone E49.1 psf) C. Calculate the design 17 ft 98 ft 60 ft di Problems 2.23/2.24

Answer 1

According to the given question: - A convenience store is to be built in New Orleans, louisiana in a location that could be classified as an Exposure C. Diagram: - Now, the Basic wind Speed = 125mph [v] the velocity pressure Co-Efficient [q_z] q_z = 0.00256 k_z k_d V^2 I where, \r\n K_z = at height is 17ft velocity pressure Exposure Co-Efficient K_z = 0.85 K_zt = Tographical factor K_zt = 1 therefore q_z = 0.00256 [0.83][1][0.85][125^2][1] = 28.9pst. Rightarrow the Design win pressures for the MWFRS. 1st Internal Pressure Co-Efficient (Gcpi) = plusminus 0.18 2nd External Pressure Co-Efficient (Cp) h = height of the building (Hft) f = Dimension Parallel to Direction wind (9ft). B = Dimension normal to wind Direction [60ft] Formula using Design Pressure (P) P = q times Gcp. Sketch of wind pressure these is the wind pressure zones
