Design of Full building

Export from CSI ETABS or SAP2000 to CSI SAFE

The design of tall buildings essentially involves a conceptual design, approximate analysis, preliminary design and optimization, to safely carry gravity and lateral loads.

How do I successfully export floors from ETABS to SAFE?
There are 3 options to Export from ETABS to SAFE:

1) Floor loads: This is a common option and should be used for most gravity floor systems, when there is no transfer of loads from floors above, or the floors from above has small influence on floor being exported

2) Floor loads and loads from above: This option is recommended when loads from above have an important effect of floor being exported (i.e transfer floor), for foundation design and also this is the recommended option to export gravity and lateral loads. In this case loads in SAFe will be separeted in two load patterns floor loads and loads from above (i.e. Dead_Above, Dead), these load patterns will be combined in one load case (i.e. DEAD)

3) Floor loads plus columns and wall distortions: This option should be used when exporting temperature loads, in this case walls and columns will be replaced by fixed supports in SAFE, and deformation will be assigned to these nodes

Notes:

Property modifiers assigned to elements in ETABS will not be exported into SAFE
Rigid area zones above columns will be automatically assigned to floors in SAFE, this is not available in ETABS
Beams in SAFE will be assigned an internal modifier of 0.1 to torsional stiffness, to avoid torsional load path
Columns above are not exported
Uniform load stets defined in ETABS are not exported
