Found drastic difference in moments of rcc beams with a plate modeled as brick wall partition wall in rcc frame structure...Moments are very low on beam and column... why it happens? Is it due to stiffness of plate ,
And what is the correct way to model plate as brick partion wall over rcc beam . Should the nodes of plate connected to nodes of beam or not ?
Please suggest as I am new one to staad
Could you Please upload the file?
As there are lot of files for complete project, so I am uploading a pic, as in this pic a partition wall is modeled and no common nodes with column, connecting nodes are only on lower and upper beam. Without this wall the steel req in the rcc column was appx. 44 cm2 but after adding this wall it comes to appx. 3 cm2 . As I am a learner so it is confusing me. You can check it by modelling a simple model with partition wall .
First of all if you are creating wall or slab panels it is always recommended that you should mesh the panels and keep proper connectivity between members & plate elements. As you have provided connection only in top & bottom all the loads are transferring through the wall element causing columns to carry less force. Please mesh the plate elements to see the change. Also you can upload the corresponding .std file for more investigation.
Now wall is created as surface mesh and with proper connectivity with all nodes but result is same , if we chk in practical way the partition brick wall will sure support the above beam and moments would be transferred to the lower beam in that case lower beam steel req. must be higher but all is also getting low, I don't have access to files so I can't upload , as I am a learner .
