Bar buckling in RC structures is a commonly-observed failure mode that adversely affects their deformation capacity. To restrict bar ductile walls, design codes only emphasises on restricting the spacing of transverse reinforcement and does not recognise importance effective stiffness ties (which combination tie leg axial spacing) to buckling. Therefore, this paper requirements for anti-bucklin...

• Experimental results of 11 RC walls scaled to 1/4 considering several damage levels and varying parameters were presented. The showed rapid severe stiffness degradation in squat subjected initial damage. with flange boundary elements had relatively greater due prior than columns. No significant deterioration ultimate strength capacity maximum deformation any level previous was observed. Struc...
