Yes, but the user must graphically define the load patterns. Refer to the program manual for further details:
Yes, the program considers the cumulative total of overlapping surface loads.
Note, it is possible to assign loads with negative magnitude which sometimes makes surface load modeling simpler.
Also note, this is opposite to the behavior of surface loads in RAM Structural System where only the top load counts. When you import surface loads from RAM SS into Concept, they are automatically adjusted to be equivalent.
Yes, when entering the magnitude of the line load, enter two values separated by a comma. For example, if you enter the following properties:
The load you create will linearly vary from 2 k/ft at the first point to 1 k/ft at the end.
You can similarly enter surface loads that slope using three magnitude values separated by commas.
Ram Concept has a hard coded set of load factors for each design code and for each rule set. You can find more about the default load factors in the manual in chapters 54-64 in the second sub-sections for "default load combinations."
When the load combinations are manually altered by the user and the load factors are changed, or when new combinations are added that do not use the expected load factors, then such an error will occur.
If the changes are intentional then the warning can be ignored.
To reset the load combinations to program presets use the Criteria menu option - Rebuild Load Combos...
We recommend saving the file, printing out the current load combinations, then using the Rebuild Load Combinations tool to reset values and finally compare the values when deciding what is best.
