Eccentricity of the horizontal axial restraint force for straight and cambered beams

الملخص EN

Theoretical formulas to predict the eccentricity of the horizontal axial restraint force (based on strain readings) for straight and cambered beams were derived.

Theoretical formulas to predict the horizontal axial restraint force were derived too.

Four portal frames were cast, two of them are with single span (one with straight beam 50mm x 60mm and other with cambered beam).

The effectiveness of cambered beams compared to straight ones are shown where there is increment in the values of axial compressive force for cambered beams.
