defined in ICC 500-2020 for the example of a multi-story building adjacent to a shelter. Shelter designers must multiply falling debris loads by a minimum factor of 2.0 to account for dynamic effects and apply falling debris loads simultaneously with the uniform roof live load. If there are multiple laydowns and falling hazards, each hazard can be considered individually and not concurrently.
the 2020 edition, and how the changes impact practicing structural engineers. These changes include Owners’ responsibility for ongoing operations and maintenance; peer review qualifications and requirements; live load and hurricane storm shelter wind load updates; and prescriptive criteria for determining whether laydown or falling debris hazard is applicable.� Full references are included in the online version of the article at STRUCTUREmag.org.
