1.1.0 External Load


External Load is verified by performing an analysis for an example taken from the text book written by Professor Yuan-Yu Hsieh, entitled “Elementary Theory of Structures” and published by Prentice-Hall, Inc., Englewood Cliff, New Jersey, 1970. An image of the text book cover is shown in Figure 1.1, an image of the example (4-3 (b), p83) is shown in Figure 1.2; and, an image of the answer of the example (4-3 (b), p421) is shown in Figure 1.3. An enlarged section of diagram and answer is shown in Figure 1.4 below.

The output of analysis result can be found and linked from here.

The elements a, b and c in Figure 1.4 are corresponding to the members 4, 18 and 9 in analysis, respectively. All the members are having uniform weight of 0.0001 kips per inch in analysis and assumed to be weightless. Other physical properties of the members, such as cross-sectional area, moment of inertia about x-axis, moment of inertia about z-axis and torsional constant of cross-section about y-axis, are assumed to be unity.
