The City of Quincy, Illinois has decided to build a 2-story small health-care facility on the edge of town. Site location: 39.883395. -91.404145. The site location is open to the north, south and west. There is a 2D Escarpment to the East of the site. The ridge is 110 ft above the site. The hill length is 300 ft. The ridge crest is 1200 ft east of the site. The building plan is attached. The roof has minimum slope with ridge at midspan of the north-south direction. The building is enclosed. The building plan is attached. A. Determine the design external wind pressures for the windward walls and then the leeward wall design pressures for the East-West and the North-South wind directions. B. Draw the Windward Wall and Leeward Wall loading Diagrams and determine the applied lateral forces at the 2nd Floor and Roof Diaphragm levels (in pounds per foot). C. Draw the Diaphragm Plan View Loading Diagrams for each level and then determine the total applied lateral force for the x-bracing frames. D. Draw the X-Bracing Frames Loading Diagrams for all bracing. Determine the service tension wind force in the x-bracing tension members for wind in the East-West direction ONLY. 100-0² 30-0 20-0 -02 DE 35'-0" BUILDING PLAN 60-0 25-0 TENSION ONLY X-BRACING TYPICAL WHERE SHOWN iwww www NORTH T ROOF 2ND FLR BUILDING WALL SECTION The City of Quincy, Illinois has decided to build a 2-story small health-care facility on the edge of town.
