Dear Engineers; Is it allowed to use the 2D-plate analysis for the raft?? Because the 2D neglects the inplane forced of the raft, Will it affect the out of plane forces?? if yes then I think it is not accurate for the analysis in presence of earthquake and wind loads coming from the superstructure, Am I right?? Or it just will neglect the results of analysis of in-plane forces without affecting the out of plane forces.? Regards
