Three storey building A three-storey steel column in a building supports roof and floor loads as...
A column in a 2-story building supports loads from the second floor and the roof. Loads were calculated and are provided below: Roof Dead = 18,000 pounds Roof Live = 14,400 pounds Wind (down) = 36,000 pounds Wind (up) = 60,000 pounds Floor Dead - 32,000 pounds Floor Live - 39,000 pounds. Using applicable ASD load combinations (refer to Ch. 2 of your textbook), determine the following: a. The maximum axial compression load in pounds for the column supporting the...
Q1. A two-storey building is braced against the horizontal load in both directions. The column for the second storey is shown in Fig. Q1. The floor-to-floor height for each storey is 3.5 m. Each beam connected to the column is 5 m long. The sizes of beam A and beam B are 250 x 400 and 300 x 500 mm respectively. The design axial load is 2000 kN. The design end moments about the major axis, which cause the column...
A steel pipe column has a length L=4.25 m and has tubular cross section with inside diameter dy=64 mm and outside diameter d2=90 mm. The column is fixed at the base and pinned at the top. The modulus of elasticity of steel is E=210 GPa. The theoretical Euler buckling load of the column is most nearly: dy dz A. 720 KN B. 560 kN C. 303 kN D. 690 KN The steel post has a length L=4 m and carries...

Draw a detailed elevation of the resulting cross-section of cut b-b for one floor only Steel Beam for a 3 storey building. The beams support a d mm thick, precast concrete floor, spanning (one way) in the direction shown in the diagram. Perimeter beams also support external cladding in the form of one leaf of 100mm thick, lightweight concrete blockwork, 3.66m high (the storey height of the building). Imposed loading on the floor is q KN/m2. NOTE 1: use Eurocode...
N=2 F=220 LLUM The figure shows a three-part column ABC, securely attached to the floor and the roof. The column has a length of 250 mm and a cross section area of 2200 mm. It is made from aluminium (E = 73 GPa). A force of F is applied at point B, a distance of 80 mm below point A. Determine the magnitudes and directions of the support reactions at points A and C. The vertical Force F is given...
The truss is constructed from three aluminum alloy members, each having a cross-sectional area of A = 1350 mm2 and an elastic modulus of E = 62 GPa. Assume a = 2.8 m, b = 9.0 m, and c = 5.5 m. If the horizontal displacement of roller B must not exceed 5.0 mm, calculate the maximum vertical load Pmax that can be supported by the truss. Chapter 5, Supplemental Question 008 The truss is constructed from three aluminum alloy...
