The interaction of shear and bond effects in the light of the reduced requirements of shear reinforcement permitted by the draft Unified Code is dealt with in this paper. The two principal topics are the effects of curtailment of main steel on resistance to shear cracking, and the dependence of the distribution of the main steel force after shear cracking on the amount of shear reinforcement provided.

Sir William Harris: Representing the President of the Institution of Civil Engineers, I am delighted that this paper is being presented jointly to our two Institutions. I had thought it was a bit double-jointed when I looked at the small print at the top of page 147 of the paper, but eventually concluded that this was merely because it takes two structural engineers to one civil engineer!

The paper describes the unusual problems encountered in designing a building structure some 179 m (586 ft) high above ground level to withstand typhoon wind loading. The building is sited on reclaimed land adjacent to the Star Ferry terminal in the Central District of Hong Kong and the methods adopted in solving the structural problems are fully described. W.E.A.
