well that's a nice point u just mentioned,but doesn't Etabs take measurement of this recess or slot in the slab geometry into account one the columns,as I've told you I really don't have much knowledge about that,but I guess large changes in geometry exceeding the code limit could cause some serious shears and moments in the slab,I think that's where dynamic analysis interferes(please someone correct me if I'm wrong) I think ACI limits this sudden change in geometry for the statical force method as it may not exceed 50% of the section through the slab in that region(also correct me if I'm wrong please,I'm not sure about the 50%).
maybe the layout of steel using the strip method is better but the results of finite element should be more realistic if done properly,then the strip method doesn't give accurate results in some cases,right?
don't know much about ram structural system,but I think I've read something about that it isn't as capable as Etabs.
To tell you the truth sir,in the company I'm training in,the other day Ram Concept gave me that I should put 59(10mm dia.) bars(rebar not punching) at a small spacing above the column,so I was shocked by the number and it's clearly wrong,so I've asked an Engineer in the company and he told me that if this happens it's clearly not right,the column was near a wall somehow,so he told me to check it manually and then it would be ok.
