Determine if a 10-ft. long 6 x14 beam is adequate to support a dead load wD= 0.3 kip/ft. and a live load wL= 0.4 kip/ft. The member is unincised-No 1 Hem-Fir with MC > 19% and a normal temperature range. Live load deflection should not exceed L/360 and total deflection should not exceed L/240. The member is part of a floor system and is repeated every 26-in. It is also fully braced by the floor sheathing and sits on a...

A steel I-beam with a span of 20 feet will support both a concentrated load of 15 kips at the beam center and a uniformly distributed load of 2 kips/ft along the entire beam length. The steel beam is Grade 50 (Fy= 50,000 psi). i) Calculate for the lightest W-shape section that will safely carry the load, with the depth not to exceed 17 inches. Provide sketches. ii) The analysis is to include (a) bending strength, (b) shear strength, and...

An A992 beam, simply supported at both ends, spans 20 ft and is loaded at mid-span with a dead load of 8.o kips and live load of 24.0 kips, in addition to its self-weight. Assume full lateral support and a compact section. Select the lightest weight wide-flange members with respect to bending capacity.

Problem 9.3.17 The beam shown in the figure has a guided support at A and a roller support at B. The guided support permits vertical movement but no rotation. Derive the equation of the deflection curve and determine the deflection d, at end A and also d, at point C due to the uniform load of intensity q=P/L applied over segment CB and load P at x=L/3. (Note: Use the second-order differential equation of the deflection curve.) q=ī MITB X

2 A simply supported beam of length L = 10 m carries both a uniformly distributed load w, of 10 kN/m and a non-uniformly distributed load with a maximum value of w2 =10 kN/m at its roller support, as shown in Figure Q2 (a). The beam is made from a I-section and the thickness for all the three rectangular members is of 10 mm. All other dimensions are illustrated in Figure 02 (b).
