ITS Strut and Tie Model Analysis VB.Net 2005
ITS Strut and Tie
Model VB.Net 2005, was My Final Thesis in ITS. This program is
similiar with CAST (Computer Aided Strut and Tie) developed by
Tjen Tjhin and Daniel Kuchma. Unfortunately this program offer more analysis
feature in analyzing STM Model of Reinforced Concrete Structure or Elements
such as Optimization of STM Model using Strength Based Optimization
rather than Minimum Energy Approach so the Optimal Design of STM Model
should be satisfied enough, Deformation was calculated using Cracking
Section of STM Model. This program still under development and more
improvement will be done in the future.
For Struts Element
it was based on ACI 318-02 configuration, but it was also avalaible for
the researcher to find suitable customize Struts Type. Tie Elements based
on the ASTM A615M with capability of showing the reinforcement more than
one layers. Optimization by using Genetic Algorithm to find
appropriate shape of STM was provided with Unlimited Generation
based on the user inputs. Interactive Stress-Ratio by colors and value
will be helpfull in checking the appropriate Struts or Tie. Real Time
Optimization will feel the optimization alive when running the Genetic
Algorithm.
The feature provided above
will be improved in the future, and I hope that this program will be the leading
in the Analyze and Design of STM Model in the future. This program was written
using Microsoft Visual C#.Net 2008 for the algorithm and Microsoft
Visual Basic.Net 2008 for the GUI, the Graphics still using GDI+ 2D,
in the future OPEN GL will be used. This program
stands in a DotNetFrameWork 3.5 SP1 platform which could be directly download
from microsoft. The minimum requirements for this programs described below :
-
Processor Pentium III 450 Mhz or eqivalent (XP), Processor Pentium III 600 Mhz or
eqivalent (Vista), Processor Pentium III 1 GHz on Windows 7 (32 Bit/64Bit).
-
128 MB Ram (XP), 512 MB Ram (Vista). 1 GB Ram (Windows 7)
-
20 MB Harddisk Space.
It is noted that this program will run in the minimum requirements but
if you were running the optimization for STM using GA then you will find that
faster processor will gives more less time than the slower ones. Till now the
program still only works with one core and its 32 bit processing only, in the
future the development of this programs will be taking the advantages of multi
core's with 64 bit processing. A few overview of this program will be shown
below.

Structure After GA Optimization [Open Picture for More Detailed Picture]
All of the overview above was
just only short brief preview, this program was also included with step-by-step
loading to get the Load-Deformation relationship with Cracking Section of STM
Model. Now I'm trying to write about Optimization using Minimum Energy Vs
Strength Based Optimization, hopefully it will be accepted in International
Journal May Be... =).
