Wind Response of Tall Buildings using Indian and Australian Standards

Abstract

India is one of the country having approx. 1.3 billion population. Continuous population increase and lack of availability of open spaces makes use of Tall Buildings essential. Increased demand of tall buildings makes wind analysis of the tall buildings considerable. The codal provisions available to carry out dynamic analysis of building subjected to wind. This paper discusses the Indian and Australian codal provisions available to carry out wind analysis of Tall Buildings. IS 875 (Part-3):1987, Indian code of practice gives procedure to calculate along wind response of tall structures. IS 875 (Part-3):2015 gives a simplified procedure to calculate along as well as across wind response of tall structures. An Australian code AS/NZS 1170.2-2002, Structural design actions - Wind actions is used carry out wind response study of tall buildings. AS 1288—2006 gives selection and installation of Glass in buildings subjected to wind.
