Tall Buildings are highly susceptible to wind induced lateral loads and is required to be designed with greater accuracy. The codal provision IS 875 (part 3) which is usually used, has a limitation that the coefficient of pressure Cpvalues available are, only for 0 and 90 degrees wind incidence angles and for standard cross sections of buildings only. Therefore wind tunnel experiments are carried out to measure wind loads which provide reliable results than the code. This Paper deals with, computational fluid dynamics, an alternative and highly dependable tool to predict the wind related phenomena on buildings. A numerical evaluation of wind pressure is done for the different cases of buildings in IS 875 part-3. Wind load obtained by using IS 875 part-3 are compared with the result obtained from CFD in ANSYS Fluent 15.0 and results are found to be in good agreement .The mean area weighted average values of Coefficient of pressure are also computed for various wind incidence angle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
