3. A Channel section is connected to a 10mm gusset plate with 20mm- diameter bolts as shown in the figure. The connecting member is subjected to dead load and live load only. The pitch distance, s=60mm (c.t.c. horizontal bolt spacing), gage distance, g=75mm (c.t.c. vertical bolt spacing) and edge distance, e for the channel and gusset plate are 65mm and 70mm respectively. Considering the following limit states, calculate the total service load capacity if the live-to-dead load ratio is 2.5. The steel is A572 Grade 50 for both members. a.
