When ductility is assumed in the model, do we need to times the analysis result by the overstrength factor (say 2.6 for limited ductile) when designing? If so what is the point reducing the seismic force in the first place then? Does AS3600-2018 mention that we need to time the overstrength...
I just found this thread Link discussing about the punching shear issue for walls on slab. However the discussion is about gravity loads only. I am wondering that won't the punching shear issue a bigger concern when it comes lateral loads like earthquake considering the stiffness of the wall is...
So I had a discussion with one of my college today, he reckons that as long as punching shear is checked and passes there is no need to check bearing or strut-tie issue for the offset column shown at RHS above because we are using fcv' when checking punching shear, which is way smaller than fc'...
Thank you for your help.
In regards to bearing, I find this from the Code. It is Australian one but the concept should be similar.
I am wondering about How I adopt A1 and N for the right hand side scenario. Please see below my question.
If A1 is that red area I mark and N should be used to...
Thanks for your quick reply.
Can I extend column reo and cog into slab for both above and below one for the right hand side scenario? If no, why can we do this for the left one?
Hi I have questions about transfer structure design. Below is two RC transfer scenarios I have and wondering which one is better and one?
The left hand one I will check the punching shear, which I believe it is critical.
For the right hand one is there anything else that I need to look into in...
