Steel Buildings Structural Design

2.1 GENERAL

2.1.1 Building manufacturer shall generally use standards, specifications, recommendations, findings, and interpretations of AISC, AISI, AAMA, AWS, MBMA, and FEDERAL SPECIFICATIONS as the basis for establishing design, drafting, fabrication, quality control methods, standards and tolerances. However, the manufacturer's design, drafting, fabrication, quality control method, standards and tolerances shall govern, unless specifically noted.

2.1.2 Structural mill sections or welded up plate sections shall generally be designed in accordance with the AISC "Specification for the Design, Fabrication and Erection of Structural Steel for Buildings".

2.1.3 Cold formed steel structural members shall generally be designed in accordance with the AISI "Specification for the Design of Cold Formed Steel Structural Members".

2.2 DESIGN LOADS

2.2.1 Design loads shall be as specified and set forth in the contract, and shall be in accordance with the manufacturer's standard design practices. Design loads may include dead loads, roof live loads, roof snow loads, wind loads, collateral loads, auxiliary loads, seismic loads, floor loads and other applied loads.

2.2.2 Dead load is the actual weight of the building system supported by a given member.

2.2.3 Roof live load is the load produced by maintenance activities, rain, erection activities, and other movable or moving loads.

2.2.4 Roof snow load is gravity load induced by the weight of snow or ice on the roof acting in the horizontal projection.

2.2.5 Wind load is the load on the structure induced by forces of wind blowing from a horizontal direction.

2.2.6 Collateral load is the weight of any nonmoving equipment or materials, such as ceilings, electrical and mechanical equipment, plumbing, sprinkler systems, etc.

2.2.7 Auxiliary load is a dynamic load induced by cranes, conveyers and other material handling equipment.

2.2.8 Seismic load is horizontal load acting in any direction on a structural system due to earthquakes.

2.2.9 Floor loads are induced on a floor system by occupants, furniture, floor weight, equipment, etc.
