What factor mainly influences Lateral Torsional Buckling (LTB)?   a.Location of the Applied Load b.The End Support Conditions c.The Stiffness of the member (whether compact, non-compact, or slender) d.The Distance between laterally braced supports e.The Applied Bending Moment Distribution/Diagram

A simply supported wood beam, reinforced with steel plates, has the cross section shown. The beam carries a uniformly distributed load of 16 kN/m over the middle half of its 4-m span. If modular ratio is equal to 15, determine the largest bending stresses in the wood and steel. 96 mm 96 mm -200 mm 8 mm 240 mn 8 mm

1 A rectangular beam has the dimensions (see Fig. 3.2b) b = 250 mm, h = 650 mm, and d = 600 mm and is reinforced with three No. 25 (No. 8) bars so that A, cylinder strength f is 28 MPa, and the tensile strength in bending (modulus of rupture) is 3.27 MPa. The yield point of the steel f is 420 MPa, the stress-strain curves of the materials being those of Fig. 1.16. Determine the stresses caused by a bending moment M 1530 mm. The concrete 61KN-m.

The bars of the truss each have a crosS-sectional area of 1.15 in.2. If oy 30 ksi. for all of the truss members, what is the Factor of Safety for each member? If the F.S. is not greater than 2.2, redesign that member assuming bars can come with areas in increments on 0.25 in.2. Note: There are at least two members that the stress results in a F.S.< 2.2 and therefore must be redesigned. 4 ft 4 ft В E 8 kip 10 kip 3 ft
