INCLINED COLUMN DES|GN
(OP)
GUYS I HAVE A PROJECT WITH INCLINED PARAMETER COLUMNS, AFTER MODELLING THE STRUCTURE USING RAM ELEMENT I NOTICED THAT THE COLUMNS DON'T TRANSFER THE AXIAL LOADS TO EACH OTHER I MEAN EVERY COLUMN CARRIES THE LOAD TAKEN FROM THE SLAB AND DOESN'T TAKE ANY LOAD FROM THE COLUMN ABOVE, I ASKED MY SUPERVISOR AND HE JUST ASSUMED THAT THIS IS THE ACTUAL CASE, BUT I AM NOT CONVINCED !!!. SO I AM HOPING THAT WE CAN DISCUSS THE BEHAVIOR OF THE INCLINED COLUMNS :) .






RE: INCLINED COLUMN DES|GN
What is the incline? IE: Is this more beam than column?
I cannot see why a column directly below another would not see the upper column's axial load (as well as a deal load due to the column directly above).
A sketch would help. Oh, and in general the behaviour of significantly inclided columns is as a beam-column (thus analysed both as a flexural element and a (slender, medium, stout) compressive member through a combined actions formula).

RE: INCLINED COLUMN DES|GN
JLNJ : I thought that first , and then i modelled a small structure just with four columns and it gave me the same results!!
on one side the columsn transfered the loads to each other and in the other side the load wasnt transfered!!1
I am using RAM ELEMENTS V 13 .

Make sure you are not applying support at the column joints.

I'm not much of a software guy, prefering my own spreadsheets and old fashioned graphics statics and hung loads for seismic. I have designed a stadium's stands this way, so you can do nearly anything that the computer can do... And you can see immediately when something doesn't look "right".
I can't help you debug your model, but I can give you a great tip for *how* to bebug your model: Create a table of the load values, live and dead, from the highest level on down. For each column work out what the tributary area would be, and run the loads down. If the computer says anything more than 20% different from this basic check (keeing in mind you need to track your loads for continuity accross supports and fixity at columns, etc) then the model is wrong.

RE: INCLINED COLUMN DES|GN
Delete or Cancel out ALL of the loads in your model (as I'm guessing you have all member self weights, etc, and probably other loads applied also).
Then... place a single concentrated point load on your model at some location, such that it will be incredibly easy to follow the load path. Run your analysis again and see what you get. Does the answer make sense. If not, figure out what in your model... or your thinking... is off.
