Roof Load Analysis Of Steel Structure

The minimum snow load on a roof area or any other area above ground which is subjected to snow accumulation is obtained by the expression.

Roof load analysis of steel structure.

The photo below shows a truss girder painted gray supporting the roof of a gymnasium. We will consider only distributed loads. The load is not shared equally by the supporting structure. 1 5 design basis for structural steelwork 1 6 steel structures eurocode 3 1 6 1 structural analysis 1 6 2 sway stiffness 1 7 steel design strength 1 8 structural integrity.

Snow loads constitute to the vertical loads in the building. Snow load wind load and the structure s own weight. 2 1 local buckling 2 2 classification 2 2 1 classes of cross sections 2 2 2 classification process. Structural loads ppy the structure.

But these types of loads are considered only in the snow fall places. Analysis of point loading is best left to engineers. Point loads occur when a weight is imposed on one spot in a structure like a column. Load combinations provide the basic set of building load conditions that should be considered by the designer.

The load combinations in table 3 1 are recommended for use with design specifications based on allowable stress design asd and load and resistance factor design lrfd. Ce 331 fall 2010 example. In order for a structure to be sound and secure the foundation roof and walls must be strong and wind resistant. Live and dead loads listed in the building code for roofs and floors are approximations of distributed loads.

The attachment of non structural elements is the. Typical design dead. The analysis and design of primary structural system. Chapter 2 resistance of cross sections.

Staad pro tutorials analysis design of steel truss type 1 day 32 if you have any problem on staad pro or need any help comment on the video or contact. Roof truss analysis 1 6 in this example a parallel chord steel roof truss is analyzed for typical dead and roof live loads. B for pipe steel. Such loads consist of the weights of the structural system itself and of all other material and equipment perma nently attached to the structural system.

Lateral loads roof diaphragm design shearwall design. Until recently analysis of complex structures proved to be difficult and consumed too much time. When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds especially if the building is located in an area known for inclement weather. The main purpose of the analysis was to identify parts of the building which experienced high stresses.

Weights of permanent 1 equipment such as heating and air conditioning systems are usually obtained from the manufacturer.
