04: (Total = 17 marks) Using seismic loading, design a four-bolt stiffened (4ES) end-plate connection for a W 18 x 55 steel beam to a W12 x 120 steel column. Material is ASTM A992 steel (Grade 50 steel) and the end plate is ASTM A572 Grade 50 steel. ASTM A490 bolts are to be used. The required shear resistance, Vu is 60 kips. i) Determine the connection design moment; ii) Determine the required bolt diameter (ASTM A490); iii) Calculate the No prying bolt moment; iv) Determine the required end plate thickness; v) Check if the column flanges require stiffeners; vi) Sketch the connection.
