Presented by Don Scott, SE, and Anurag Jain, PhD, PE this session will start with a focus on wind loads on a building using the Envelope Procedure of Chapter 28 from SEAOC’s Wind Design Manual based on IBC 2018/ASCE 7-16. This problem will be solved using both Part 1 and Part 2 methodologies and will highlight the effects of altering the roof configuration (hip and flat) for the same building.

The session will also include another example utilizing the provisions of ASCE 7-16’s Chapter 27 on Directional Method to determine the wind load for design of the Main Wind Force Resisting System (MWFRS), and Chapter 30, Part 3: Buildings with mean roof height, h > 60 feet method for computing the Components and Claddings (C&C) pressures on the building’s façade. A rectangular plan shape 14-story steel moment frame building with an eccentric podium on the bottom floor is analyzed for this example. Dimensions of the building in this design example were purposely selected to demonstrate the process for evaluating the gust effect for flexible buildings, Gf. The process for computation of design pressures for components and cladding is also illustrated in this design example.
