Development of Software Package in Excel for Along and Across Wind Response of Tall Building
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 7
Abstract
The calamitous damage to life and property due to wind storms is experienced in many parts of the world including India, which has a huge coastal area. This has embolden many investigations on the determination of wind loads on different structures. Usually the estimation of wind loads in Buildings is carried out using codes and standards, whose enumeration are generally based on wind tunnel tests performed on selected building structures with common shapes. For example in India, A draft code of IS-875 (Part 3) for wind loading gives specifications for rectangular square, cylindrical and some typical Industrial Structures. Wind pressure estimation in buildings having shapes different from that specified on codes and standard requires wind tunnel studies. Also, Wind tunnel studies are expensive in terms of resources and time. The project suggests the Dynamic analysis for determination of wind pressure (loads) in buildings and structures. MS Excel is commanding enough for the calculation of wind pressure distribution to more cases than those currently covered by limited wind tunnel data. Some comparisons were also done using STAAD Pro with the dynamic response of building considering some examples. MS Excel has been used to determine the along wind and across wind response of a tall building. A draft code CED-37 (7792) was used to generate data for the along and across wind response of a tall building by varying various parameters as height, width, depth, terrain category, basic wind speed and force coefficient for the building. Finally, calculation of response of along and across wind of any dimension of building can be done with the draft code provisions and necessity of that is discussed
