Course Length:  1 hour

Purpose and Background

This three-part webinar series discusses how to use the wind load provisions of ASCE 7-16 Minimum Design Loads for Buildings and Other Structures. The series will cover the basics of wind engineering including the atmospheric and aerodynamic effects of wind on buildings. The changes recently adopted for use in ASCE 7-16 will be a prominent part of the material. The changes include revised wind speed maps, changes in external pressure coefficients for roof components and cladding and the addition of pressure coefficients to use for roof mounted solar arrays.

The series will cover all methods used to develop wind pressures on buildings - the directional procedure, the envelope procedure, and simplified methods where wind pressures are determined from tables of results based on exposure classification, height and building characteristics. Wind pressure determination for both the Main Wind Force Resisting System (MWFRS) and Components and Cladding (C&C) are included. Wind pressures are developed for several buildings including variations on the pressures caused by changing the exposure and height of the buildings.

This webinar is being offered early in the outreach process for ASCE 7-16 to give engineers a chance to get familiar with the new provisions long before their local community adopts a building code that requires the use of these new provisions. Engineers may want to practice the use of these new provisions to determine the real effects on designs and on client requirements. Other engineering tools such as computer software will not likely be available yet.
