The parameters effect on the structural performance of damaged steel box beam using Taguchi method

Abstract

In the current study, the influence of notch or opening parameters and the positions of the applied load on the structural performance of steel box beams up to failure was investigated using Finite Element analysis program, ANSYS. The Taguchibased design of experiments technique was used to plan the current study. The plan included 12 box steel beams; three intact beams, and nine damaged beams (with opening) in the beams web. The numerical studies were conducted under varying the spacing between the two concentrated point loads (location of applied loads), the notch (opening) position, and the ratio between depth and width of the notch with a constant notch area. According to Taguchi analysis, factor X (location of the applied loads) was found the highest contributing parameters for the variation of the ultimate load, vertical deformation, shear stresses, and the compressive normal stresses.

Experimental Analysis of Channel Steel Member under Tension Load with Damage in the Unconnected Legs

“…Furthermore, few studies have considered other construction elements, such as steel beams and steel columns, and the impact of the damage on the test results [ 30 , 31 , 32 ]. Regarding the properties of the steel element, El-Taly and Abd El-Hameed [ 33 ] studied the effect of the damage in relation to the steel beams and demonstrated that the factor of the location of the applied loads in relation to the location of the damage was the highest contributing parameter for the variation of the maximum load capacity, shear stresses, normal stresses, and vertical deformation. Furthermore, the factors of the ratio of the depth and the width of the damage were the most significant control factors affecting the tensile and compression strains and normal stresses.…”
