Load Combination
Object serves for definition a load combination. The combination is created from the existing load cases in the model, in StructuralLoadCase sheet.
| Column header | Data type | Example / enum definition | Required | Description |
|---|---|---|---|---|
| Name | String | COM1 | yes | Human readable unique name of the object |
| Description | String | variable_1 + dead load | no | The description of the load combination |
| Category | Enum | ULS (Ultimate Limit State) SLS (Serviceability Limit State) ALS (Accidental Limit State) According national standard Not defined |
yes | The category of the load combination |
| National standard | Enum | EN-ULS (STR/GEO) Set B EN-ULS (STR/GEO) Set C EN-Accidental 1 EN-Accidental 2 EN-Seismic EN-SLS Characteristic EN-SLS Frequent EN-SLS Quasi-permanent IBC-LRFD ultimate IBC-ASD ultimate IBC-ASD serviceability IBC-ASD seismic IBC-LRFD seismic |
yes, If Category =According national standard | The National code application |
| Type | Enum | Envelope Linear Nonlinear |
no, optional for Categories: SLS (Serviceability Limit State) Not defined |
For type 'linear', the exact content of the combination is presented. For type 'envelope', linear combinations can be composed based on relations defined in StrucutralLoadGroup. For type 'nonlinear', the exact content of combination is presented. Used for non-linear calculations. Other inputs like initial stress or deformation are to be set in analysis software. |
| Load factor # | double | 1.35 | yes, If Category is not "According national standard" | Load factor of the load case. # means indexing of the Load factor column, e.g. Load factor 1, Load factor 2, … Load factor 99. It depends on how many load cases are considered in the combination. If the category is "According national standard", then the load factor is expected to be set by the national standard in the software, not prescribed in SAF. |
| Multiplier # | double | 0.9 | yes | A multiplier for e.g. increase the selfweight of the structure . # means indexing of the Multiplier column, e.g. Multiplier 1, Multiplier 2, … Multiplier 99. It depends on how many load cases are considered in the combination. |
| Load case name # | String | LC1 | yes | Valid name of the load case (StructuralLoadCase). # means indexing of the load case name column, e.g. Load case name 1, Load case name 2, … load case name 99. It depends on how many load case is considered in combination. |
| Id | String | 39f238a5-01d0-45cf-a2eb-958170fd4f39 | no | Unique attribute designation |
