Assignment on Virtual Work 2023-2-1 (3)

QUEENSLAND UNIVERSITY OF TECHNOLOGY SCHOOL OF CIVIL ENGINEERING & BUILT ENVIRONMENT EGB275 – Structural Mechanics Assignment 1 (Virtual Work) Due on 18 August 2023 (5% of the Overall Assessment) 1. Figure Q1 shows a truss structure subjected to a set of loads. Use the Principal of Virtual Work to determine the horizontal and vertical displacement at point p . The cross-sectional area is 980 mm 2 for each member and E = 240 GPa. (50%) 2. Determine the vertical displacement in m at Point C of the simply supported beam shown in Figure Q.2. Consider EI in kNm 2 is constant and use the virtual work method. (50%) Parameter Calculation Table ( NO MARKS will be given if the following parameter calculation table with correct parameters calculated is not included in your submission) Round your parameters to ONE decimal place only Student ID (Example: N15035109 – 1st Digit is 1, 2nd Digit is 5, 3rd Digit is 0, …) 𝑌𝑌 1 (kN): 10.0 +5.0 * (3 rd + 4 th digits of your ID) (25) 𝑌𝑌 2 (kN): 20.0 +10.0 * (3 rd + 4 th digits of your ID) (50) w 1 (kN/m): 2.0 + (5 th + 6 th digits of your ID) (8) P (kN): 5.0 +10.0 * (4 th + 5 th digits of your ID)/9.0 (13.9) L (m): 5.0 + 5.0* (4 th + 5 th digits of your ID)/6.0 (11.7) Figure Q.1 Figure Q.2 Y 1 (kN) Y 1 (kN) Y 2 (kN) 12 m L
