APPROXIMATE FRACTURE

= 0.456 in mw = as fy (d - a/2) = 0.88 x 60,000 x (6.2 - 0.456/2) a simplified sketch of the wall cross section for analysis is as shown: lab testing produced first yield at loads of 14,402 and 12,772 lb, which corresponds to flexural strengths (mw)of 36.0 and 32.0 kip * ft. the wall was tested in an upright position. if friction is
