The frame shown below is fixed at A and C, and is supported by a roller at B. Use the numbering shown for the members and joints and determine the support reactions at all supports of the frame using the Stiffness Method. The 10 kN force is applied at the middle of the beam, and the 12 kN/m load is uniformly distributed on the column Take E = 200 GPa, 1 = 300(109) mm+ and A = 10(10-) mm2 for...

General Information (Problems 2–4) The envelope of a four-story steel building (risk category II) is shown below. Resistance to lateral loads (wind and earthquake) in the direction shown is provided by a steel braced frame on the interior of the building.

The single-story unbraced frame shown below is subjected to dead load, roof live load, and wind load Figure 1 shows the results of a first-order analysis relative to the columns of the frame. The axial load and end moment (also equal to the maximum moment in the column) are given separately for the different load cases (i.e., dead load, roof live load, and lateral wind load). All vertical loads are symmetrically placed and contribute only to the Mnt moments (i.e.,...

The frame below has wind load and dead as shown. Use w(Dead) = 6
kip/ft and w(Live) = 3 kip/ft, L = 30 ft and H = 15 ft. The beams
and columns have modulus of elasticity E of 29000 ksi and moment of
inertias I(beam) = 2000 in4 and I(column) = 800
in4. Similarly they have cross-sectional areas A(beam) =
20 in2 and A(column) = 25 in2. Consider that
the wind can act in both horizontal directions.
