The Structural Performance Of Vierendeel Frames Using Approximate Method And Computer Programs

Abstract

The Vierendeel girder definition is open-frame N-truss without

diagonal members, with rigid joints between the top and bottom chords

and the verticals are known also as open-frame girder, this research is

conducted to study the structural performance of different Vierendeel

frame. Three models of the Vierendeel (1, 2& 3) were studied for their

structural performance using approximate method and structural analysis

programs such as SAP2000 and ROBOT STRUCTURAL for different

loadings that were calculated according to British code BS 5950. The

results of the analysis were illustrated in graphical presentations. It was

taken the differences in bending moments and shear forces for the three

models and they were tabulated by approximate method and SAP 2000

and Robot 2015. It was found that the maximum values of bending

moments and shear forces were in Vierendeel model (1), and that the

minimum values of bending moments and shear forces were in

Vierendeel model (3). After examining the structural performance of the

three models and comparing the results with each other, it was observed

that the Vierendeel model (3) is better compared to the Vierendeel model

(1) and (2).
