Abstract
"ENGINEER", established in 1973 by The Institution of Engineers, is a Journal for dissemination of Engineering knowledge, published quarterly.Cover DescriptionCover images show a schematic diagram of a Pumped-Storage Hydroelectricity (PSH) facility and one of the promising sites for PSH in Sri Lanka. The latter image was obtained from the publicly available JICA report on “Development Planning on Optimal Power Generation for Peak Demand in Sri Lanka”. The Institution of Engineers, Sri Lanka acknowledges JICA for the image.If you are interested in contributing an Original Technical Paper based on research by the author(s) (intended for Section I) or an Original Article of Professional or Technical interest related to Engineering. (Section II) to this journal please go through the publication checklist which can be downloaded from here.
Highlights
Around the world, construction of tall buildings has been increasing over time to overcome the scarcity of land
That is the main reason for higher degree of variation in across and torsional wind responses obtained through different codes/standards than in the case of the along wind response
Wind induced axial loads estimated from the British standard are found to be very low compared to other standards since it is based on mean wind loading and across wind loading is ignored
Summary
Construction of tall buildings has been increasing over time to overcome the scarcity of land. Due to the complex nature of wind and its interaction with the structure, several limitations and significant discrepancies are found between the international standards in prediction of wind effects on dynamically sensitive tall buildings [1], [4] and [5]. Selection of most suitable wind design standard with understanding of its capabilities and the limitations is utmost important to make a precise estimation of wind induced responses. This will eventually assist the designer to arrive at a safe and optimum structural scheme during the conceptual design stage. Importance of selecting a suitable wind design approach during the preliminary design to predict dynamic wind effects and their impact on tall building design is emphasized
