Minimization the deflection and cost of reinforcement frame using doe

الملخص EN

The stiffening of a rectangular frame is taking place by using bars.

Those bars are distributed longitudinally, transversely, inclined and mixed shape.

The theoretical deflection of frame free edge is calculated and compared with the (FEM) using MATLAB and ANSYS software programs.

A good agreement is found from the (FEM) model as compared with the theoretical and ANSYS results.

Different bar distributions gave a different torsional resistance and deflection.

A higher torsional resistance is found in the transverse and cross shape of bar distributions.

Minitab program is used to analyze the results and minimize the deflection and cost by (DOE).

In which, the effect of input factors and their interactions has been studied.

The main effect on the deflection and cost has been observed in the inclined bars.

A higher reduction in the deflection and cost has been observed in the existence of longitudinal and transverse bars, respectively.
