Summer Spartan

Hello visiter! This weeks works involves optimizing parameters that affect the stiffness of the beam. Parameters affecting stiffness of beams: Slenderness ratio Short column/long column Concrete grade   Different types of loading: Torsion Compression Tension Lower the slenderness ratio, higher the buckling load.   Concrete filled tube is less advantageous in short columns.   As the concrete grade increases, the deformation decreases.   Concrete filled tubes have high resistance to torsional loads.   Concrete filled tubes have low deformation in axial compression, but low resistance to fracture in tension.      Currently working on applying torsion and axial loading at same time.   Thanks for visiting!

Weekly update: Leaning more about FEA and Concrete grades was this week's moto: A FEA is carried out to find strength of HST and CFST structures. The summary is as follows. • Initially both Hollow Tube and CFST geometries are built  • Buckling analysis is carried out in both Hollow Tube and CFST domain • The stresses are very high in the small slenderness ratio of Hollow Tube region and for nonlinear analysis the stresses are very less in the high slenderness ratio of CFST. • The results show the Hollow Tube buckling load carrying capacity less compared to the CFST buckling loads. Initially both theoretical and analysis values are compared to check Finite element solution with theoretical calculations. Also graphical plots are represented to find effect of thickness, diameter, and slenderness ratio on stress and buckling strength estimates. This study focuses on modelling of concrete filled steel tube (CFST) column under axial loading. The main parameters ...
