Contribution of typical non-structural components to the performance of high-rise buildings based on field reconnaissance Li, B., Hutchinson, G. L., & Duffield, C. F. (2010).

The current design approach to tall-building design in most of the regions in the world requires the structural skeleton to resist vertical and lateral loads, under both the ultimate and serviceability loading conditions applied to the building. Nonstructural components such as infill walls, facades, stairs and so on are considered as non-load bearing components. These components are assumed to be detached from the primary structure in the design of high-rise buildings. However, because of different types of physical connections, interactions between the structural skeleton and the non-structural components do occur. Both structural and non-structural components participate in resisting structure movement. Various researchers (Mahendran and Moor, 1999; Sev, 2001; Hutchinsonet al , 2006; Li et al , 2007, 2008a, 2008b, 2009a, 2009b) have identified that non-structural components make a considerable contribution to the overall structural performance. From these communications, it was confirmed that in practice, non-structural components are seldom considered in the structural design, neither are they included in the advanced design analyses. Australia is recognised as a very diverse country in terms of its climate and environment. A large proportion of the land in Australia is semi-arid or desert and the major cities and its population are principally located along the south-eastern and south-western coastlines (Australian Bureau of Meteorology: http://www.bom.gov.au/lam/climate/). The climate of Australia is significantly influenced by the surrounding oceans. Except for the wide area of desert and grassland in central Australia, in major cities hosting most of the population, the climate varies from temperate along the south-eastern coastline to subtropical on south-western coast and tropical and equatorial in the north. Generally, cyclones are severe in the northern part of the country and only a small area in the south-western part of Australia (near Perth) has potentially high seismichazard level. In the cities discussed in this study (Melbourne, Sydney and Gold Coast), even though both types of hazard are rare, they should not be ignored in the design of structures. Thus, in the design of tall buildings in these three cities, wind load almost always governs the lateral stiffness but earthquake and cyclone resistance still needs to be considered carefully. It was confirmed by the structural engineer (Arup Melbourne Office) that owing to its coastal location and the weather conditions in Melbourne, wind load governed the overall design of the lateral resisting system of the building.
