There have been some request from engineers for clarification on wording in Table 1607.1 Section 27 for “Primary roof members exposed to a work floor” and how to apply to 2000# concentrated load per “Single panel point of lower chord of roof trusses or any point along primary structural members supporting roofs over manufacturing, storage warehouses, and repair garages”.


Does this apply to buildings with trusses and does this apply to steel moment frame buildings that do not have trussed?

Thanks in advance for your input.
