Building Design for Wind Forces: A Guide to ASCE 7-16 Standards


Book Description

Expert coverage of ASCE 7-16–compliant, wind-resistant engineering methods for safer, sounder low-rise and standard multi-story buildingsUsing the hands-on information contained in this comprehensive engineering guide you will be able to design and construct safer buildings that will better withstand extreme wind forces. Written by a recognized structural design expert, the book explains the general concepts and principles involved in the design of buildings and structures for wind forces. Structural systems used to resist wind forces are outlined and explained, in the context of both low-rise and high-rise buildings. Building Design for Wind Forces provides easy-to-follow summaries of complex ASCE 7-16 wind load provisions and shows how to apply the corresponding design procedures using practical examples. A detailed discussion of typical structural damage caused by extreme wind events such as hurricanes and tornadoes is presented along with design recommendations. Current wind engineering activities and recent research developments are discussed, and a general overview of wind tunnel procedures and an introduction to the concept of database-assisted design (DAD) is provided. Building Design for Wind Forces covers:•Wind forces and wind effects on buildings and structures•Wind load provisions of the ASCE 7-16 standard•Damage to structures caused by extreme wind events•Wind engineering activities and research trends•Structural systems for lateral loads•Tall buildings•Wind design procedures and wind load parameters•Wind loads on the Main Wind Force Resisting System (MWFRS)•Wind loads on Components and Cladding (C&C)•Wind loads on building appurtenances and other structures•Wind tunnels and the wind tunnel procedure•Database-assisted design (DAD)




Physical Models


Book Description

Physical models have been, and continue to be used by engineers when faced with unprecedented challenges, when engineering science has been non-existent or inadequate, and in any other situation when the engineer has needed to raise their confidence in a design proposal to a sufficient level to begin construction. For this reason, models have mostly been used by designers and constructors of highly innovative projects, when previous experience has not been available. The book covers the history of using of physical models in the design and development of civil and building engineering projects including bridges in the mid-18th century, William Fairbairn?s Britannia bridge in the 1840s, the masonry Aswan Dam in the 1890s, concrete dams in the 1920s, thin concrete shell roofs and the dynamic behaviour of tall buildings in earthquakes from the 1930s, tidal flow in estuaries and the acoustics of concert halls from the 1950s, and cable-net and membrane structures in the 1960s. Traditionally, progress in engineering has been attributed to the creation and use of engineering science, the understanding materials properties and the development of new construction methods. The book argues that the use of reduced scale models have played an equally important part in the development of civil and building engineering. However, like the history of engineering design itself, this crucial contribution has not been widely reported or celebrated. The book concludes with reviews of the current use of physical models alongside computer models, for example, in boundary layer wind tunnels, room acoustics, seismic engineering, hydrology, and air flow in buildings.

Wind Tunnels and Experimental Fluid Dynamics Research


Book Description

The book "Wind Tunnels and Experimental Fluid Dynamics Research" is comprised of 33 chapters divided in five sections. The first 12 chapters discuss wind tunnel facilities and experiments in incompressible flow, while the next seven chapters deal with building dynamics, flow control and fluid mechanics. Third section of the book is dedicated to chapters discussing aerodynamic field measurements and real full scale analysis (chapters 20-22). Chapters in the last two sections deal with turbulent structure analysis (chapters 23-25) and wind tunnels in compressible flow (chapters 26-33). Contributions from a large number of international experts make this publication a highly valuable resource in wind tunnels and fluid dynamics field of research.
