Problem Description
Overlapping surface loads on two-way decks are ignored in the RAM Frame Analysis. This results in incorrect member forces and reactions. The defect can also affect seismic load calculation and P-Delta effects. The RAM Concrete Analysis is not affected.
Reason
The program is mishandling the overlapping surface loads and then ignoring them in the analysis. The defect is model specific and dependent on how the overlapping surface loads are modeled. Models with multiple surface loads on a two-way deck that do not overlap are not affected.
Solution
Fixed in v15.05.00
