The width of the expansion joint is 30 mm in a cement concrete pavement. The laying temperature is 30°C and the maximum slab temperature in summer is 70°C. The coefficient of thermal expansion of concrete is 10 x 10-6/°C and the joint filler compresses upto 40% of the thickness. The spacing between expansion joint should be

Design criteria for structural loading

The different loads such as loads due to self-weight (dead load) and external loads such as live load, wind loads, seismic load, snow load, and other loads and load combinations that influence the design of a building are called structural loading. The nature of the applied load differs from changes in the location, design, and type of materials used. The design criteria require that structures must be designed and constructed to be able to withstand all load types that are expected to act upon the structure and render its usage for the designated purpose. The structural members such as beams, slabs, columns, and foundations help the structure to withstand the applied load. There are different institutes such as ASCE and ACI that provide building design codes to assure minimum safety requirements and quality of the structures.
