analysis simple beam in FEAPpv

[akdavoudi]

Hi,

I am a fresh user of FEAPpv. I have a basic question
I want to analysis sample beam as per attach file "Beam01.jpg"
so I wrote  input file in Feappv as this

FEAP

and qustions
1. Does it true?
2. If yes, How can I get reactions?


Very appreciate to any answers :)

1. What theory do you want to  use to solve the beam problem?  You show a 2-d mesh with quadrilateral elements.  If this is what you intend, you will need more elements through the depth.  Also you should mesh so that nodes occur where you want to put the boundary conditions.

2. If you want to use beam theory then you need to use a FRAMe element, which has 2-nodes with 3-dofs/node.  Loads will be in the material data.

3. Your material data is incorrect.  Consult manuals for proper specification.

4. Before you solve the problem you always need to check that the data is understood by FEAPPV.  Consult the output file (Obeam01.txt in your case).

Tank's a lot for your answering.
