Design of steel structure building followed the codes and specification of American Institute of Steel Building Construction (AISC), American Codes and Standards or Bangladesh National Building Codes (BNBC-2006). If required any other codes may be applicable. It is Univend Structural Steel Ltd. policy to comply with latest issue and supplements of these codes.
Design Loads: Considering the climatic condition round the year buildings design for the following loads:
Dead Load: Total weight of the buildings & its components.
Live Load: Loads during erection, maintenance & usages throughout the life time of the structure.
Wind Load: According to BNBC
Collateral Load: Fire sprinklers, false ceilings, mechanical systems, electrical systems, etc.
Seismic Load: According to BNBC
Mezzanine Load: The dead load of the mezzanine framing, including all finishes.
Thermal Load: Loads of structural members as a result of temperature variation.
Building Materials Weight: The weights of the most common Building materials are the follow: –
Floors – Platforms – Roofs – Walls
