"ASCE7-16W.xls" Program Version 2.1 <br /> Figure 6-9 - Design Wind Load Cases of MWFRS for Buildings of All Heights <br />Case 1: Full design wind pressure acting on the projected area perpendicular to each principal axis of <br /> the structure, considered separately along each principal axis. <br />Case 2: Three quarters of the design wind pressure acting on the projected area perpendicular to each <br /> principal axis of the structure in conjunction with a torsional moment as shown, considered <br /> separately for each principal axis. <br />Case 3: Wind pressure as defined in Case 1, but considered to act simultaneously at 75% of the <br /> specified value. <br />Case 4: Wind pressure as defined in Case 2, but considered to act simultaneously at 75% of the <br /> specified value. <br />Notes: 1. Design wind pressures for windward (Pw) and leeward (PL) faces shall be determined in <br /> accordance with the provisions of Section 27.4.1 and 27.4.2 as applicable for buildings <br /> of all heights. <br /> 2. Above diagrams show plan views of building. <br /> 3. Notation: <br /> Pwx, Pwy = Windward face pressure acting in the X, Y principal axis, respectively. <br /> PLx, PLy = Leeward face pressure acting in the X, Y principal axis, respectively. <br /> e (ex, ey) = Eccentricity for the X, Y principal axis of the structure, respectively. <br /> MT = Torsional moment per unit height acting about a vertical axis of the building. <br />4 of 4 4/4/2025 11:50 AM
