Paper format. National Examinations, December 2013 — 98-Civ-A2 Elementary Structural Design. Three hours, CLOSED BOOK (handbooks and textbooks permitted). Seven questions in three parts: Part A (A1–A3, steel), Part B (B1–B3, reinforced concrete), Part C (C1, timber). A candidate answers two from Part A, two from Part B and the one question in Part C — five in total, all of equal value. All seven are solved here, because the set is a study resource rather than an exam script.
Design standards. Steel to CAN/CSA-S16, concrete to CAN/CSA-A23.3, timber to CAN/CSA-O86, with load combinations from the National Building Code of Canada.
Reference texts.
Check: load factors. Note 6 on page 1 states “All loads shown are unfactored, unless otherwise noted”, so the factoring is left to the candidate. Throughout this paper the point loads drawn on the figures are taken as live load (factor 1.5), concrete self-weight as dead load (factor 1.25), and the wind load named in B3 as wind (1.25D + 1.4W). Question A3 asks for the maximum factored load, so no further factoring is applied there. Where a grade is not stated for a fabricated element the plate grade named in the question governs.
