Don’t do the extra credit. Just the regular problem. The single-story unbraced frame shown below is...
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.,...
Problem 22. Two-story, one-bay unbraced frame shown below is subjected to gravitational dead and live loads and wind lateral load. The columns are made of W18x65 (I,-1070 in , Ag- 19.1 in2, r-7.49 in, ry-1.69 in) and beams are made of W18x71 (1, 1170 in). The table below shows the moments at the ends of column 4-5 due to three load cases. The frame is fully braced in lateral direction. Use Grade50 steel Bending is about strong axis. All gravity...
A W14 × 74 of A992 steel, 16 feet long, is used as a column in an unbraced frame. The axial load and end moments obtained from a first-order analysis of the gravity loads (dead load and live load) are shown in Figure P6.7-2a. The frame is symmetric, and the gravity loads are symmetrically placed. Figure P6.7-2b shows the wind load effects obtained from a first-order analysis. All loads and moments are based on service loads, and all bend-ing moments...
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 gravity load system, floor and roof diaphragms, and the lateral load system for the orthogonal direction are omitted from the figure. GRAVITY BF Roof 15 ft - - - - - - 15 ft WIND 3 15 ft...
3. For the single-storey braced frame shown below, determine the design axial loads of the members under gravity plus wind loads. All the members are pinned-connected and the self- weights of the member are included in the dead load. в, Vw Ps 200 kN V,-50 kN 6.0 m
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. Determine: The...
PROBLEM 3: (40points) Figure shows te clevation and main floor plan for five-story bailding. The building is clad with nonstructural precest pansl There are no sructural walls or other bracing. The floor besms in the north-south direction are all 450mm wide with an overa depth of 750mm. The floor slabs are 150mm thick Assume all the floors are to be designed for a superimposed dead load of S KPa plus alive load of 12KPa, which includes a 3.5KPa partition loading....

Questions 5-8 A steel frame shown below is subjected to combined uniformly distributed gravity load (w 2 kips/f) and a horizontal earthquake load of H-10 kips Both the beams and the columns are made of W12x120 section having a yield strength of F 45 ksi. The Young's modulus of steel s E-29,000 ksi. The distributed load w is used to simulate the self-weight of the beam, the load transferred from roof slab, as well addition superimposed dead loads. The self-weigh...
