STRUCTURAL DESIGN OF TALL BUILDINGS

摘要

Building at height presents unique challenges both in terms of design and construction. For the structural engineer, the key factor is the relative magnitude of the lateral loadings (wind and seismic) when compared to the vertical loadings. The lateral loadings will almost certainly influence the size and strength of the structural elements. The other issues that will influence the design of these structures include the requirements of the core, the distribution of services, the fire strategy, axial shortening and tolerances, and the dynamic behaviour of the building. There are also buildability factors to consider, such as floor construction time and hoisting of materials.
