Homework Answers
The edge beams of the slabs will carry half of the slab load. The central or middle beams will carry full slab load. The load intensity is transformed into uniformly distributed load before calculation.

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...

The structural steel framing plan of the figure represents a floor system for a narrow commercial building. The floor is to support a 6 in. thick reinforced concrete slab, a live load of 150 psf and an additional future load of 20 psf. Use the Allowable Stress Design (as per the class reference materials) and ASTMA36 steel for all members, use 0.6 Fy as...

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.,...

Consider a floor plan and its overall dimensions as given in Assignment 2 and repeated in Figure 1 for convenience. The plan shows a series of spans in the Y-direction and one simple span in the X direction. The beam on axes 1, 2 and 3 could assumed to be simply supported. Concrete strength fc-30 MPa, maximum aggregate size is 20 mm, beams are of exterior exposure. For all beams, 10M stirrups are used. Reinforcement steel yield strength fy 400...

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....

How
do I solve this?
Problem 2(50 points) The roof of the Edwin A. Stevens building is to be redesigned to accommodate a billboard for Stevens Institute of Technology. The new billboard will weigh 40 kips and be supported equally by two columns located 9 ft from the rear of the building. The beams supporting the new roof will be simply supported as shown. (Note there is a 5 ft overhang at the front of the building). For the grade...
