A common question is whether pattern loading can be done in Prokon SUMO, similar to how it is created in Continuous Beam (CB). The answer is yes – Prokon SUMO can generate pattern load combinations using its load combination generator.
For example, when modelling a beam with two spans in SUMO, you can:
- Apply dead load (DL) to both spans.
- Assign live loads to each span in separate load cases.
- Define the parameters for these load cases, including the Type of Action and Combination Category.
- Use the Combination Generator to create Load Combinations for Structural Resistance (STR).
When generating STR, you’ll notice that the load cases in SUMO align with those in Continuous Beam (CB) if the same beam is modelled in both platforms. In this instance you will see that in SUMO, for Load Combination C3 and C4 corresponds to Case 2 and 3 in Continuous Beam Design.
Below you will see that the results compare favorably from Continuous Beam (CB) and SUMO:
In SUMO, the beams can also be split into multiple segments for greater accuracy. SUMO does not display the effects of own weight; However, it is still included in the analysis.
Overall, Pattern Loading is feasible in SUMO when applied correctly, and the results compare well with those from Continuous Beam (CB).
