The support bracket shown below is subjected to a factored load Pu-220 kip, and is to be attached to a column flange with two identical vertical rows of ASTM A325-N, 1" diameter bolts. The bolts depicted in the figure are for illustration only, and may not represent the actual number of bolts needed. Filler plates will not be used. Bolts are to be spaced at 3" on center. The load eccentricity is ex=9". Assume that the connection design is controlled by bolt strength only (ignore any other limit state). a) Using the elastic method of analysis, calculate the smallest number of bolts per vertical row required to safely resist the applied load, if the connection is a bearing-type connection b) If the design obtained in part a) is to be used in a slip-critical connection, what is the maximum load Pu that may be applied? ex Pu The support bracket shown below is subjected to a factored load Pu-220 kip, and is to be attached to a column flange with two identical vertical rows of ASTM A325-N, 1" diameter bolts.
