Snow Loads

Snow Loading is a frequent and costly cause of structural performance failures. In fact, snow is the controlling roof load in half of US States. As a structural engineer, you must be familiar with snow loads. This book will provide you with the tools you need to understand and compensate for snow loads in structural design. ""Snow Loads: A Guide to the Use and Understanding of the Snow Load Provisions of ASCE 7-02"" is the only book of its kind that provides a detailed authoritative interpretation of snow load provisions of ASCE Standard 7-02. Included are examples of flat roof loads, sloped roof loads, partial loads, as well as all types of conventional drift loading. Readers will benefit from the frequently asked questions section, which addresses and demonstrates the correct implementation of the provisions of ASCE 7-02, such as unique snow loading cases and ways to mitigate drift loads on existing roofs due to new additions. This guide is essential for practicing structural engineers. Twelve informative chapters cover: Ground Snow Load, Flat Roof Snow Loads, Sloped Roof Snow Load, Partial Loading, Unbalanced loads, Drifts on Lower Roofs, Roof Projections, Sliding Snow Loads, Rain-on-Snow Surcharge Loads, Ponding Instability and Existing Roofs, and Frequently Asked Questions. Over 70 figures and tables clearly illustrate snow load scenarios. In addition, each chapter contains numerous worked examples that will aid you in understanding and applying difficult wind loads concepts.

Wind Loads

Published 25 March 2020
Wind Loads: Guide to the Wind Load Provisions of ASCE 7-16 provides a comprehensive overview of the wind load provisions in Minimum Design Loads and Associated Criteria for Buildings and Other Structures, ASCE/SEI 7-16. In this helpful guide, authors Coulbourne and Stafford focus on the provisions that affect the planning, design, and construction of buildings for residential and commercial purposes.

Whereas the 2016 revision of ASCE 7 has retained the previously reorganized wind load provisions, the important changes in the ASCE 7-16 wind load provisions are
  • Modified wind speed maps for the country west of the hurricane-prone region;
  • A fourth wind speed map for Risk Category IV structures;
  • Revised methodology to determine exposure category;
  • Addition of a ground elevation factor to the velocity pressure equation;
  • New provisions for roof top solar arrays, canopies, and bins, tanks, and silos; and
  • Revised pressure coefficients for components and cladding for sloped roofs.
Wind Loads provides users with tools and insight to apply ASCE 7-16 in everyday practice. This updated guide introduces readers to the relevant sections of the standard and provides an extensive overview of the design procedures and the revised wind speed maps.

This guide includes 14 chapters with 10 worked examples of real-life design problems applying the appropriate use of analytical and simplified procedures for calculating wind loads for a variety of common structure types, as well as answers to more than 30 frequently asked questions, grouped by topic.

This book is an essential reference for practicing structural engineers, as it offers the most authoritative and in-depth interpretation of the wind loads section of Standard ASCE/SEI 7-16.
