A circular hollow section (CHS) member with steel grade S355, subjected to compression, is to be used as an internal column in a multi-storey building. The column has pinned boundary conditions at each end, and the inter-storey height is 4m. Classify the cross sections according to EC3-1-1. Figure below shows the cross section and the column condition d= 244.5 mm t= 10.0 mm A= 7370 mm Wely = 415000 mm? Wply = 550000 mm | = 50730000 mm* 4.0 m Section properties for 244.5x10 CHS

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.
