Question 1 (11 points) Consider a real-world engineering frame, formed of 198 structural members. For the needs of a structural analysis using the Finite Element Method, each structural member of the frame is discretisation using 9 beam elements. What is the total number of beam elements, with which the aforesaid frame is discretized? Your Answer: Answer Question 2 (11 points) Consider a real-world 3D engineering frame. For the needs of a structural analysis using the Finite Element Method, the aforesaid structure is discretized using beam elements and, in total, 132 nodes have been formed. What is the size of the associated stiffness matrix (before the write-off of any equations due to the presence of supports)? Your Anno
Answer Question 7 (11 points) Consider a 2-node bar element, with cross-sectional area A, length L and modulus of elasticity E. If a new material is considered with modulus of elasticity Enew, and Enew/E-124, then what is the ratio (Knew / K) equal to? (noted, Knew and K denotes the stiffness of the bar element when Anew and A are considered, respectively. Your Answer: Answer
