Elastic behavior of corrugated web girders with square opening

الملخص EN

This paper presents an elastic parametric study for the trapezoidal corrugated web with a square opening subjected to a shear load.

A series of finite element (FE) analyses using the ABAQUS program is carried out to study the influence of square opening on trapezoidal corrugated webs.

A parametric study is conducted in this paper to investigate the effect of key parameters on the shear buckling coefficient (?? ) including the height of the web, width of the flat fold, depth of corrugation, the ratio between the flat fold and inclined fold, eccentricity and size of the square opening.

By using the finite element model, the eigenvalue buckling analysis is obtained and verified using theoretical models.

The results have shown that the increase in the height of the web plate leads to a decrease in the value of the shear buckling coefficient ??.

Also, it is found that the changing in the corrugated depth shown a clear influence on the shear buckling coefficient.

Also, it is concluded that the effect of horizontal eccentricity in a big opening has a small influence on the shear buckling coefficient while in a small opening no changes are found in the shear buckling coefficient.

On the other hand, it is found that there is no effect of changing the vertical eccentricity on the values of the shear buckling coefficient.

Finally, design curves are proposed to obtain the shear buckling coefficient for ?? with different values of horizontal eccentricity.

Also, for (?
