You should note in this connection that the analyses in the building model are always based on characteristic load values. When all storeys have been analyzed the total loads acting on the building down to the foundation are available. Subsequently the next floor is analyzed and so on. The top ceiling is analyzed in the FE application, the bearing forces are computed and transferred as loads to the next ceiling. The horizontal loads are subsequently distributed over the bracing components according to the ratio of the bending stiffness.
It is also able to analyze loads from inclinations in dependence to the computed vertical loads and you can generate additional horizontal load cases by entering manual loads. As with the wind load application WL, the building model can generate wind loads in the x and y direction depending on the building geometry and the selected parameters. In addition, you can apply horizontal loads to the building.
The input options allow you to define a floor slab as well as foundations on different levels, continuous vertical components outside of the slab and wall-type girders within a storey. Alternatively, you can generate storeys individually on the basis of different DXF files for instance. To add new storeys you can copy a previously defined storey and freely modify the copied data subsequently. You should note in this connection that the self-weight loads of the ceiling and beams as well as of walls and columns are automatically analyzed by the application. As with the FE application PLT, the available input options also include concentrated, line and temperature loads in addition to the distributed loads. Optionally, you can define load cases that allow the consideration of a load per field already in the load analysis, for instance.
The load input is simplified by the definition of distributed loads over the total outline that you can enter together with the storey data. The desired design standard and the materials are already defined in the building model too.
This applies among other things to the suspension of loads over several storeys.įurthermore, the simplified approach to the distribution of the horizontal loads is only suitable for non-sway systems that are braced with wall plates because a frame effect between a column and a beam, for instance, cannot be included in this analysis approach.Ī storey is entered by defining a slab outline, block-outs, walls, columns, beams, parapets and other geometric particularities suc h as thickness or bearing direction areas. You should note in this connection, however, that due to the two-dimensional approach, the application can only represent certain load transfer situations by means of idealized equivalents. The transfer of geometric and load data to the design applications in particular saves the user a lot of time because all parameters relevant to the design are transferred from the building model to the design application. You can easily and quickly calculate residential, office and administrative buildings in a comprehensive man ner.
The Frilo Building Model offers a simplified approach to the analysis of an entire building.
