Kutu Kesitli Kiriş-Kolon Birleşiminde Mesh Kalitesinin Şekil Değiştirmeye Etkisi

Abstract

By the recent earthquakes occurred in our country, the utilization rate of the steel structure especially in the industrial structure has increased when compared to concrete structures. But when the places where steel construction preferred are considered; either architectural and statically project or technical infrastructure which participates in production and mounting steps can’t render service to country-wide equally. For this reason, design, manufacturing and application services are tried to be resolved by the local facilities. This situation is easily accessible in the building design and the hallow-section profiles were processed foreground. But hallow-section profiles bring local buckling problems under the effect of shearing force and bending loads together depending on their section geometry. Local buckling problems observed in frame systems formed by hollow-section profiles cause unpredictable capacity losses in the problems and lead to a risk for industrial structures. That’s why, numerical analysis programs as well as the appropriate management and interpretation of solution algorithms of these programs are crucial since it is possible to predict structural weaknesses in the design of buildings resistant to earthquake in Turkey where the seismic activity is widespread and thus designing buildings. In this present study, a sample which is completed experimental analysis is numerically modeled with ANSYS and analyzed. The numerical model which is verified by experimental analysis has tried to capture the real behavior and solution was analyzed for commands about different meshing techniques on the loading apparatus. Within this scope, the obtained results are compared and the effects of mesh technique and mesh quality on joint behavior is tried to be shown. 1. Giris
