Hi all,
I was recently part of a ~65 m tall steel building design where (owing to the unusual geometry) the fundamental period of the building is about 3.5 seconds.
Lateral resistance is provided by a combination of moment frames and bracing.
American code: f= 10/#storeys = 10/16 = 0.625 Hz =...
Hi all,
I have a project where the architects want to add some decorative features to a concrete column.
The nominal cover is 40 mm.
The architects wish to add an additional 60 mm for this "decorative concrete".
My senior engineer said up to 40 mm additional concrete is generally okay (w.r.t...
Hi all!
I am undertaking an analysis on a large building with shear cores and moment frames.
I need to understand how much %Shear the walls are carrying compared to the frames, is this possible?
There is a way to show pier forces in ETABS (Display Tables➜Results➜Wall Results➜Pier Forces)...
Hi all!
I am relatively new to structural engineering design and am working on a project in a moderate seismic zone.
To cut to the chase:
My senior engineers want to use 400 MPa yield strength for rebar in the main structural elements.
The concrete compressive strength is 40 MPa (cube...
Hi all!
I recently started a job at a structural engineering practice outside of Europe where English is not the first language.
Being from the UK, I am familiar with the terms "Primary Beams" and "Secondary Beams". However, in my new firm, the engineers like to use the terms "Girder" and...
Hi all,
I'm working on a 9-storey building and I want to extract the seismic cumulative shear forces from the storey plots.
Upon closer examination, it seems like there is a mismatch between the base shear shown in the storey response plots and the base shear for the same load case in the base...
Hi all,
I'm quite new to ETABs and still a young inexperienced structural engineer, so apologies in advance!
In ETABs, I have decided the reinforcement I would like to use in my beams and specified the end reinforcement overwrites for my beam sections. For example:
However, when I run the...
