I am assuming that the planar walls are much longer than core walls and therefore much stiffer. In this case then they would theoretically attract the bulk of horizontal load at 3rd floor and below.
However this means that the horizontal forces must be transferred via diaphragm action in the...
shemp,
I have to pick you up on your sentence: "I would venture a guess to say that this topic is probably THE most unregulated topic by the codes in structural engineering that there is."
Progressive collapse is well regulated and understood in UK and it never ceases to amaze us...
Refer to British Standards which include for progressive collapse design.
Main points:
1) Check what would happen if you remove a column. Will structure hang (large deflection acceptable) or will it fail? If it fails, how big an area will fail? If a large portion of structure will collapse upon...
For the modelling I also find Robot useless for more complicated models. I usually generate nodes in a simpler frames package and then export them to a spreadsheet, and then into Robot (making sure x,y and z directions are same!)
Then I join the dots to make the more complicated structure.
For...
asdf,
Do you know for a fact that the engineer is responsible for the rework and modifications? Do you know whether it is loopbear's responsibility to write such a letter?
No, I didn't think so!
I have been following this thread from the start and it is a pity that loopybear has been censored...
This is the best site I have found so far. It also includes links to other sites including an American one.

Mick21,
I use Masterseries everyday and find some things to be good and some not so good.
Maybe it is best for a company of your size to identify the strengths of several packages and run several licences on each of them rather than restricting to one package. This allows constant montitoring...
There are several excellent packages for analysis and design in the UK. All of them seem to have something that the others don't, but none of them have everything. Therefore it is important to carry on as you are and get demos for any software you are interested in. If a software supplier can't...
There are several packages about which could help you. Where are you based i.e. what codes do you need to design to?
In the UK you can search through www.nceplus.co.uk under IT and there is a list of several companies which have a product to suit your needs e.g. CADS, CSC.
Some of these may...
Try LUSAS - www.lusas.com or call Terry Cakebread on 02085411999
It will still probably exceed your budget but it will be far cheaper than that quoted for Ansys above.
They are willing to come and talk to you to discuss your particular needs and will go into great detail to demonstrate that...
I do not design a lot of flitch beams but recently designed one using Superbeam 4 software and a hand check of the results.
A building control officer, who will remain nameless, is insisting that "in his experience" the plate I have used is not thick enough but he refuses to back this...
