止 Q.1 Using the lightest W section shape to design the compression member AB shown in Fig. below, the concentrated service dead load and live load is PD-40kips and PL 150kips respectively. The beams and columns are oriented about the major axis and the columns are braced at each story level for out-of-plan buckling. Assume that the same section is used for columns. Use Fy-50 ksi. 32456 A

02. Design a W shape beam is used to support the loads for plastered floor, shown in Figure. Lateral bracing is supplied only at the ends. Depend LRFD and Steel Fy=50ksi. Note: The solution includes compute C, Check deflection at center of beam as well as shear capacity) B P10.5 P=140 W C Hing Hing 159 A 15.ft
