Paper format. National Examinations, May 2014 — 98-Civ-A2
Elementary Structural Design, 3 hours, closed book (handbooks and textbooks permitted).
Seven questions in three parts: Part A (A1–A3, steel), Part B (B1–B3, reinforced concrete)
and Part C (C1, timber). The candidate answers two from Part A, two from Part B and the single
Part C question — five solutions in all, of equal value. All seven are solved here,
because the set is intended as a study resource. Page 1 states that
all loads shown are unfactored, so the load factors are applied below rather than assumed
to be built in.

13.8 (beam-columns), 13.13 (welds), Tables 1 and 2 (element slenderness classes).
- CISC, Handbook of Steel Construction — section property tables and the standard
beam load/moment diagrams referenced by Question A1.
- CSA A23.3, Design of Concrete Structures — Clauses 10 (flexure and axial load) and
11 (shear, simplified method).
- CSA O86, Engineering Design in Wood — Clause 6 (sawn lumber), Tables 6.3.1B
(Beam and Stringer specified strengths) and 6.4.2 (service-condition factors).
- National Building Code of Canada — load combinations
1.25D + 1.5L.
Check: the figures on page 3 of the paper are hand-drawn; every dimension, support type and load below was read from the printed figures. The 300 kN, 250 kN, 300 kN and 80 kN forces are treated as
live load (factor 1.5) because the paper labels them only as unfactored applied loads;
concrete self-weight is the sole dead load and carries 1.25.
