What came after moment distribution method?

What came after moment distribution method?

What came after moment distribution method?

(OP)
According to http://en.wikipedia.org/wiki/Moment_distribution:

From the 1930s until computers began to be widely used in the design and analysis of structures, the moment distribution method was the most widely practiced method.

What is the best method to use to analyze two dimensional frames with computers?
I need to program a method from scratch that analyses beams that are similar to the one in the Wikipedia article above.  

RE: What came after moment distribution method?

The stiffness matrix analysis method is what most computer programs use to analyze structures.
 

RE: What came after moment distribution method?

Sounds like a college essay question but finite element all the way.

RE: What came after moment distribution method?

Finite Elements ?

multi-span beams can also be solved as a redundant beam, whihc would point you towards unit load method, etc

RE: What came after moment distribution method?

Buy a program - say from Archonengineering.com.  Costs like $40 or $50.  Not worth an hour of your time to program it!!

RE: What came after moment distribution method?

i'd agree, if you're so backed up with work (or looking for work) that you haven't got some hours to spare.

working it out for yourself teaches you something (possibly to buy a canned program next time !?) but it makes you really understand the theory.

RE: What came after moment distribution method?

(OP)
I actually need the theory for a program I am writing. Yes I know, this will be about a months work to code!

RE: What came after moment distribution method?

You could program the direct stiffness method as described in Dawson, T.H., Offshore Structural Engineering, Prentice-Hall, Inc. 1983.

RE: What came after moment distribution method?

I think the Cantilever and Portal Methods of Building analysis came after MD,or about the same time.

RE: What came after moment distribution method?

i'd research methods for solving redundant structures, i like unit load method myself.  three moment equation is another that lends itself easily to a beam on many supports (that's typically where we'd use MD), but in structural maybe you use it more for frames ??

RE: What came after moment distribution method?

Does it need to be a second order analysis? or is first order sufficient?
