Course of Space Structures Modeling of Space Structures Written test, February 15 th, 2022 Exercise 1 The structure in the gure is composed of four trusses. Three of them have constant section ( A2, A3, A4). One of the trusses see gure below has a section which is variable with quadratic law: it is equal to A0 at the two ends and A1 at the middle. Solve the problem using 2-node linear nite elements and determine the reaction force R. (Unit for result: N ) Data A0 = 5mm2 A1 = 10mm2 A2 = 20mm2 A3 = 30mm2 A4 = 40mm2 L = 1800mm α = 30deg E = 72GPa P = 2kN
