Key Differences
≠IS 875 contains unit weights for numerous materials specific to Indian construction (e.g., various local timbers like Deodar and Sal, Mud Phuska insulation, Surkhi mortar), which are not found in international standards like ASCE 7 or Eurocode 1.
≠For partitions where locations are not fixed, IS 875 recommends a uniformly distributed load derived from the actual partition weight (min. 1/3 of weight per metre run). In contrast, ASCE 7 often addresses movable partitions by specifying a minimum superimposed live load (e.g., 15 psf or 0.72 kN/m² in offices), which is a different classification and application philosophy.
≠IS 875:1987 is a significantly older standard (though reaffirmed). Modern codes like ASCE 7-22 and Eurocodes are updated more frequently and are more likely to include data and guidance for contemporary materials like engineered wood products, composites, and advanced facade systems.
≠International standards like Eurocode 1 often provide a range of values for material densities based on source, moisture content, or composition, encouraging more specific engineering judgment. IS 875 tends to be more prescriptive, providing a single value for many materials.
Key Similarities
≈The fundamental definition of dead load is identical: it is the gravity load due to the self-weight of all permanent structural and non-structural components of a building.
≈The basic calculation methodology is universal across all standards, based on summing the products of the volume of each component and its corresponding unit weight (material density).
≈All standards provide extensive tabulated data of unit weights for common construction materials like concrete, steel, masonry, and glass, which serve as the primary reference for designers.
≈All codes explicitly state that the weight of permanent finishes (e.g., floor screeds, plaster, ceiling tiles) and fixed service equipment (e.g., HVAC ducts, plumbing, electrical conduits) must be included in the dead load calculation.
