the calculations. WIND BRACING. [41 SWAY-RODS (i). The simplest case of wind bracing is shown in Fig.84. Considering one bay alone as braced, the system maybe analyzed as follows: Referring to the upper storyof a framework, as shown in Fig. 88, Px = pHlLx wherePx = resultant wind pressure on upper… … Fig. 88. the stress in the diagonal, and the tension in this diagonal,making an angle 0 with the horizontal, must be T = — sec ft2 The diagonal tension in the second story from the top willbe T% — + Pj sec 0, where P = wind pressure on any single story, assuming them to be of equal height. ~ -f- P…
