Question 1 [25 Marks] A steel end plate (S275, thickness=10 mm) is used to connect a column and a beam as shown in Fig.1. The connection for column is a group of bolts (M 20) and the connection for beam is fillet welds. Given Q=200 kN, T-30 kN and My=12 kN-m (applied at centriod of the bolt group), it is required to: (1) Determine the design shear (Fv,Ed) and tensile (Ft,Ed) forces at the most critical bolt; (2) Check if the bending strength for the plate is sufficient according to EC3; (3) Check if the strength of welds is sufficient according to EC 3 using the simplified method. 8 40 My T 2@75=150 40 N 40 O 2000 85 O -Plate *↑ Column 10 40 Figure.1.
