Question

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, member force in AB and horizontal displacement at B Enter your answers in the space provided. B diwum Dimensions: Loading: D 0 0 0.0005 rad/m EA IN a — b Provide your answer for the followings to an accuracy of 2.5% and up to 6 decimal places for deflection Absolute Value Unit Direction A) Horizontal displacement at point B under the individual actions of cases 1, 2 & 3 Case 1 Distributed load acting on member BC only, AB = Case 2 Initial curvature in member CD only, AB. Case 3 Support settlement at point D only, AB-0= Unit Direction Case 4 B) All actions combined Absolute Value At point D: Vertical reation Dy= At point A: Vertical reation Ay= Member CD: Axial force Nco= At point B: Horizontal displacement AB=
