Optimisation of Structural Analysis and Design of steel space structure using MATLAB

Optimisation of Structural Analysis and Design of steel space structure using MATLAB

(OP)
Hi Experts

Thank you for sharing your knowledge and experience with us...
I have been struggling about Optimisation tool in Matlab

I am working on Design optimisation of steel space structures.
I have coded the analysis and design of the structure in MATLAB. The analysis was coded by using STIFFNESS METHOD. As you might know that there are 107 Universal Beams and 64 Universal Columns. All these are variables. However, these variables are applicable for each individual member of the structure, so I can be able to find the minimum weight after the achievement of the Cross Sectional Resistance.


Can you please give me a clue on how to use the optimisation App to solve my problem. It will be appreciated if you could provide me with a source or a private expert so I can contact.


Many thanks

RE: Optimisation of Structural Analysis and Design of steel space structure using MATLAB

I can't help with your specific question, but I just want to note that optimizing a structure like this involves more than just minimizing weight. I'm picturing a lot of connections in this structure and specifying connection-friendly members can optimize from a cost/schedule standpoint just as much, if not more than, reducing the weight.

RE: Optimisation of Structural Analysis and Design of steel space structure using MATLAB

Start thinking simple, use an unit shape for all members, then refine by stress/force criteria. Iterations are required to achieve optimum design - least weight yet force resistant.

RE: Optimisation of Structural Analysis and Design of steel space structure using MATLAB

Could I suggest that this thread could focus on the principles of design optimisation procedures, i.e. not MATLAB or even computer related.

Any discussion of the specifics of optimisation in MATLAB should go in the thread in the MATLAB forum.
