One of a high rise structure that I have working with now is having T and 135 degree L shaped RC walls. Refer the attachment for the shapes. In order to design these sections for N and M, PMM interactions is to be generated for the each whole sections. In order to do so, It requires that the total action moments for a defined axis to be found from my analysis. But from the analysis results, I would only able to get the moment results(M22, M33, M12) per unit length of each leg about their local axes but not as a whole. Please advise me to convert these results in to a defined global axis of each whole sections(T and 135 degree angle). Is it just simple addition about each leg or more than that????? It would be appreciate that you could explain separately for each two sections. Thanks.
