Finite Element Analysis of a Ribbed Roofing Panel under Static Flexure

Abstract

This study focuses on analyzing the response of a typical ribbed aluminum panel under flexure. A three dimensional finite element model was developed to stimulate the static flexure behavior. The model is a 2.0m (length) x 1.0m (width) x 0.005m (Thickness) with a rib height of 0.038m, crest width of 0.019m and pan distance at 0.055m between intermediate ribs. The load deflection response of the aluminum panel under different flexural loading condition was stimulated. The linear material properties, displacement, stress and strain captured were discussed under static conditions. From the result obtained, the maximum uniformly distributed load carrying capacity of the ribbed aluminum roofing panel under flexure, considering the linear material properties is 665N.

Finite Element Analysis of Fiber Cement Corrugated Roofing Sheet under Bending

“…Examples of those products are corrugated sheets for roofing, flat panels for sliding, façades and partitions [1]. Corrugated roofing system is most preferred and widely used in rural and industrial areas of Nigeria because it allows mechanical and dry consumption methods to cover large areas without the need for ceiling compounds to prevent leakage [2].…”

“…Numerical methods provide a general tool to analyze arbitrary geometries and loading conditions [5]. Among these numerical methods, Finite Element has been extensively used with success [2]. However different approaches for the numerical simulations can be considered: a linear elastic analysis with geometrical non-linearity or a physical nonlinear analysis [3].…”
