A) Consider the frame in the adjoining figure, which is subjected to the following actions: Case 1) Distributed load acting on member BC only Case 2) Initial curvature I member CD only Case 3) Support settlement at point D only Determine the horizontal displacement at point B for each of the above cases. B) Consider load case 4 below where all actions act simultaneously Case 4) All actions combined = Cases 1 +2+3 Determine for case 4 the support reactions,...
The two-span continuos beam (ABC) shown in the sketch below carries a uniformly distributed load, w, in the left side span AB. Assume that EI is constant. Use the method of virtual work, together with the principle of relative displacements, to determine the following quantities in terms of E,I,L and w: The two-span continuous beam (ABC) shown in the sketch below carries a uniformly distributed load, w, in the left side span AB. Assume that El of the beam is...
Questions 5-8 A steel frame shown below is subjected to combined uniformly distributed gravity load (w 2 kips/f) and a horizontal earthquake load of H-10 kips Both the beams and the columns are made of W12x120 section having a yield strength of F 45 ksi. The Young's modulus of steel s E-29,000 ksi. The distributed load w is used to simulate the self-weight of the beam, the load transferred from roof slab, as well addition superimposed dead loads. The self-weigh...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
