Comparison between experimental and numerical of RC-wall with opening / Tajul Fikri Salleh Masri

The Finite Element Method is a numerical solution technique applicable to a broad range of engineering and physic problems. It is a basic calculation for almost all computer design system. This Finite Element method addresses the difficulty by dividing the region into small sub regions and used as a basic calculation. Therefore this study was carried out to determine the comparison between manual and finite element of analysis of RC-wall with opening.
For the preliminary analysis of RC wall with opening, the study is done based software (FEM-linear and FEM- nonlinear) and lab work. Therefore the model for this project is a RC wall with openings with 1.2m meter height. The dimension of the RC wall is 1400mm x 1200mm x 75mm where the l/h ratio is 1.0 with target strength of the concrete are, fcu = 30kN/mm2.
The RC wall is designed using FEM-linear and FEM-nonlinear and will be tested after 28 days due to lab work procedure.
The conditions of the RC wall with openings that will be designed and tested are:
a) A simply supported RC-wall with openings is subjected to uniformly distributed load at top of the wall.
b) A simply supported RC-wall with openings is subjected to point load at the mid-top of the wall.
c) A line supported RC-wall with opening is subjected to point load at the mid-top of the wall.
d) A line supported RC-wall with opening is subjected to uniformly distributed load at top of the wall.
In solving these problems, computer software called LUSAS using the fundamental concept of finite element was used. The software is the most suitable for both simple and complicated structural analysis. The software was applied for every model with similar number of elements, nodes, load, sizes and material properties. A comparison was made between the models with the laboratory work.
