Civil Engineering CIVE3203 A Stru. Anal. Homework No. 4 1 Homework 4: Due 11:30AM, Friday, Nov. 18, 2011 Question 1 [30 marks] Determine the vertical displacement of joint d in the following truss for each of the following cases: 1. due to the applied loads, and 2. due to a temperature change of +50 C of the bottom chord (members df and ef ) Use E = 200000 MPa, α = 12 × 10 - 6 mm/mm/ C . For the bar sizes, all members that are in compression under the applied loads have A = 1000 mm 2 and all other members have
