Horizontal wind loads will act on the building exerting pressures on the vertical face that may be approximated as uniform within each of the three “layers" as shown. From empirical expressions for wind pressures at the midpoint of each of the three layers, we have a pressure of 781 N/m² on the lower layer, 1264 N/m² on the middle layer, and 1530 N/m² on the top layer. Determine the resisting shear stress that the foundation must develop to withstand this wind load. 50 m 20 m 20 m 20 m P3 MEC32P-2 2Q2122 M1Q2arrow_forwardSeismic Principle Candidate Questions. 13.
