Design Loads 2 Textbook Reading Simplified Structural Analysis and Design for Architects, Revised 2 nd Edition, by Rima Taher, published by Cognella, 2021 Chapter 7 Design Loads, Sections 7.1, 7.2 and 7.3. Design Loads 3 Design Loads The design loads for buildings can be classified as: Dead loads Live loads Environmental loads Design Loads 4 Dead Loads Dead loads are the loads due to the permanent parts of a building such as the weight of the floors, beams, walls, columns… Table 7.1 lists the weight of some typical construction materials. See Table 7.1 in the textbook for typical weights of some construction materials. Examples: - Wood shingles: 2 psf - Ceramic tile (3/4-in): 10 psf Design Loads 5 Live Loads Live loads represent probable loads on a building structure due to occupancy and use. These loads are generally considered uniformly distributed over a floor area in psf. Live loads generally account for the weight of the occupants, furniture, some equipment… On roofs, the live load includes an allowance for maintenance workers and equipment. Buildings that contain heavy machines or large concentrated live loads must be specifically designed for such loads. Design live loads are generally given in the building codes function of the type of occupancy of a building. Design Loads 6
Special provision must be made for impact loads. These loads are caused by vibration due to moving loads such as the operation of elevators. Structures supporting live loads that tend to cause impact must have their loads increased by a certain percentage. See Table 7.2 in the textbook for examples of uniformly distributed live loads based on occupancy types according to the International Building Code (IBC). Design Loads 7 Examples of Live Loads Stores - Retail first floor: 100 psf Office buildings Offices: 50 psf Lobbies and 1 st floor corridors: 100 psf Residential Typical residential floor loads (rooms): 40 psf Design Loads 8 Environmental Loads Environmental loads are normally due to the environment. Examples are wind, snow, rain, earthquake forces, soil and hydrostatic pressures, temperature… These loads are out of the scope of this course. Design Loads 9
