Analysis of Regular Perforated Metal Ceiling Tiles

Abstract

Metal ceiling tiles can be used for a variety of space, including commercial, office and other public spaces. They are widely used for suspending ceilings and other architectural applications in a range of different perforation patterns to suit both mechanical and aesthetic requirements. These perforated panels made of steel, aluminum, bras, etc. are also known as stamping plates or sheets depending on its thickness and area of usage. In this study, perforated ceiling tiles are modelled as rectangular thin plates with various hole patterns which are simply supported on all its boundaries. The main idea is to find out the effect of the holes on the bending behaviour of the perforated plate which is the governing attitude of a ceiling tile. The other parameters which determined about the behaviour of the plates are deflection, moments and stresses. The analyses were performed on various models systematically by number, diameter and location of holes. As a result of these analyses the relationships between the applied force and maximum values of internal forces have been calculated by using APDL codes based on Finite Element Method to find out the optimum hole pattern. According to analysis results; 3D graphics are developed to design proper hole patterns for Regular Perforated Metal Ceiling Tiles.

Investigation of Hole Shape Effect on Static Analysis of Perforated Plates With Staggered Holes

“…In the studies generally experimental and numerical methods have been used. Numerical methods that are using finite element method is the most preferred one among the solutions [1][2][3][4][5]. Perforated plates with inplane loading are also interested with some researchers [6], [7].…”
