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.

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.
