Wind Design for Roofs
Wind design of roof systems can be complicated. Let’s face it, there’s math involved! The latest version of ASCE 7 has only added complexity to the design process. This presentation will focus on understanding the design process laid out in ASCE 7-16, as well as discuss the similarities and differences between the three versions of ASCE 7 (-05, -10 and -16). Changes to ASCE 7-16 influence related wind design methods. This presentation will also discuss updates to FM’s wind design process and the requirements within their related Loss Prevention Data Sheets (e.g., LPDS 1-28 and 1-29).

LEARNING OBJECTIVES
Describe the similarities and differences between the three versions of ASCE 7 and the roofing industry-developed methods to determine loads. Identify the foundational elements involved in determining wind loads acting on a building. Differentiate between the load side and the resistance side and understand how each are presented within the roofing industry. Explain the recent changes and impact of the new information contained in FM’s Loss Prevention Data Sheets 1-28 and 1-29.
