Paper format. 16-Civ-B2 Advanced Structural Design, December 2019, 3 hours, closed book (handbooks and textbooks permitted). Seven design questions of 20 marks each in three parts — Part A (steel, do two of three), Part B (reinforced concrete, do two of three) and Part C (prestressed concrete, do question C1); five solutions constitute a complete paper. All seven are solved here, because the set is a study resource rather than an examination script.
Design data given on page 1. Solutions to the latest CAN/CSA S16 (steel), CAN/CSA A23.3 (concrete) and CAN/CSA O86 (timber). All loads shown on the figures are unfactored. Structural steel is G40.21 300W unless noted, so $F_y = 300\ \text{MPa}$; reinforcement is 400W, so $f_y = 400\ \text{MPa}$. Load combinations follow NBCC: $1.25D + 1.5L$.

Page 3 of this paper carries all four figures and nothing else, and the machine-readable extraction of that page is unreliable. The paper draws a pin as a triangle and a roller as a circle (Figures 1 and 4) but draws plain hatched ground with no symbol at A and F in Figure 2 and at A and E in Figure 3; those four bases are therefore taken as built in (fully fixed). Figure 2 dimensions the right-hand column as 4 m + 4 m but leaves the left-hand column undimensioned: it is drawn between the same beam line and the same base line, so it is taken as 8 m. Figure 3 gives no dead/live split for its four point loads, so the single factor 1.5 is applied to them.
