Paper format. 98-Civ-B2 Advanced Structural Design, National Exams May 2016 — 3 hours, closed book (design handbooks permitted). Seven design questions of equal value; any five constitute a complete paper, and all seven are solved here.

Design data (page 1). Design in SI. Concrete f'c = 30 MPa; structural steel Fy = 350 MPa; rebar fy = 400 MPa. Prestressed work: f'ci = 35 MPa at transfer, f'c = 50 MPa, n = 6, fpu = 1750 MPa, fpy = 1450 MPa, finitial = 1200 MPa, losses in prestress = 240 MPa. Marks: Q1 (12+5+3), Q2 (15+5), Q3 (16+4), Q4 (14+6), Q5 (10+5+5), Q6 (6+5+5+4), Q7 (10+5+5).
