- PROBLEM: Light grade steel channel was used as purlin of the truss. The top chord of the truss is inclined 1V:3H and the distance between the trusses is 5m. The purlin weighs 100n/m and spaced at 1m apart. The roof carries superimposed dead load of 1000 Pa (including its weight) and the ceiling carries a load of 1200 Pa. Roof live load is assumed to be 1500 Pa. The roof is part of the building located at a place where the design wind speed is 240 kph. Assume the unit weight of air to be 12 N/m3. The windward coefficient is 0.20 and the leeward coefficient is 0.70. For this problem, assume that the allowable bending stress of beam is 60% and 75% of its yield strength in the strong and weak axis respectively. Assume all loads passes through the centroid of the section. Properties of C 250x85 ; Sx= 122 x103 mm3 ; Sy= 49 x103 mm3; Fy=300 MPa; Fbx (Allow. Bending Stress)=0.6Fy;Fby (Allow. Bending Stress)=0.75Fy What is the ratio of the actual to allowable bending stress for load…A 10-ft long cantilever balcony is constructed of 2x12 Doug-Fir-Larch (DFL) joists. Determine the controlling load combination and corresponding load duration factor for moment and shear. (Hint: see NDS Supp. Appendix B2 for load combinations.) Each 2x12 carries: dead load (DL = self-wt + decking = 50 psf, spaced at 2-ft on center), snow (SL = 250 plf) construction load (CL = 300 plf)The framing plan of the flat roof of a gymnasium is shown. De- termine the design free-body dia- gram of beam A-B. There are no joists on the roof system. Dead load is D = 20 lb/ft2. Check load combi- nation number 2 [L.C.2] only. Dis- card rain R and snow S loads in your analysis.
- The floor plan of a building in the preliminary stages of design is shown below. The connec- tions between all members are simple shear connections (shear tabs). This floor space will be used for a restaurant dining area. The floor decking is galvanized 20 gage N3 Formlok with 5 inch slab thickness. Due to the long beam spans, the flooring will consist of lightweight concrete. Calculate the dead load, wD (kip/ft), applied to beam B2 based on tributary load analysis for the given loads and floor span direction. In addition to the weight of concrete, include the self-weight of the corrugated steel decking and allow an additional 35 psf dead load (total of fixed partitions, HVAC, and drop ceiling). Neglect the beam self-weight. Draw an FBD of beam B2 showing the calculated dead load, wD. Report the maximum bending moment (kip-ft) in beam B2 due to dead load. What is the minimum uniform live load, Lo (psf), for this occupancy? Calculate the live load, wL (kip/ft), applied to…Determine the adequacy of the No.1 Southern pine, 2 x6 bottom (tension) chord in thetruss shown below.1. Load combination, DL + S, controls.2. No ceiling attached to the bottom chord3. Connections: Single row of 3/4-in.-diameter bolts4. The uniform load transferred from the roof system to the top chords is 240 lb/ft.5. The force in the bottom tension chord TAB = 6912 lb.6. Assume CM = Ct = Ci = 1.0The floor system used in a school classroom consists of a 189-mm. reinforced stone concrete slab and a 3.29 kPa live load. Sketch the factored loading that acts along the joist BG and side girder ABCDEF.
- Design a square tied short column to carry an axial dead load of 180 k (800 KN) and an axial live load of 160 k (712 kN). Determine the required ties and draw the cross-section showing the bar arrangement. Use f = 5 ksi (35 MPa), fy = 60 ksi (420 MPa), and a steel percentage of 3 percent.A timber formwork system utilizing 3 x 12 S4S joists spans a length of 12 feet (simply supported). The system carries a load of 175 psf (dead load plus live load). At what spacing should the joists be placed? Assume Douglas fir-Larch No. 2 (fb = 1,450 psi).(a) The detached servant room of a quarter is having internal size of 3.0mxx4.50m. It is to be covered by a roof of RCC. The dead load on roof 4.5kN//m^(2) and the live load is 1.50kN//m^(2) Design the slab by I.S. Code method. Assume grade of concrete as M25 and grade of Steel as Fe415.
- An A36 channel section is used as a purlin in a roof system with spacing of trusses at 4.5 m apart. Purlins are to be places at the joints and at the mid points of each top chord member. Sag rods are places at the center of each purlin. The total gravity loads consists of a dead load of 1.2 kpa roof surface (including weight of roofing and purlins) and a live load of 1.4 kPa of the roof surface. Assume the steel section is a compact section and that all loads are applied at the top flange of the purlins. Use LRFD method. (Refer to the figure for the value of equal soacing = S) Properties: Sx = 221.28 x 10^3 mm3 Sy = 19.01 x 10^3 mm3 Zx = 258.82 x 10^3 mm3 Zy = 38.51 x 10^3 mm3 Lp = 0.90 m Lr = 3.34 m Cb = 1.30 m Fy = 248 mPa Use LRFD design method.
