Abstract

This investigation about the structural performance of sustainable self-compact concrete walls exposed to eccentric axial regularly dispersed loading, including the effect of aspect ratio (AR) and slenderness ratio (λ) by one-way and two-way action. The experimental program includes testing ten wall panels, the eccentricity of the loading system equivalent to one-sixth of depth. These wall panels are separated into four groups, each one consisting of three specimens. first and second groups clarify the aspect ratio (H/L) effect. The results indicated for decreasing AR from (0.75 to 0.625), (0.625 to 0.5), and (0.75 to 0.5), the increase of final load is about 10 %, 15.91%, and 27.5%, also the decreasing of lateral displacement is 20.1%, 21.4%and 29.2% respectively for one-way action. The increase in final capacity 6.52 %, 12.24%, and 19.56%. also about 2.76%,19.87% and 22.08% decreasing in lateral displacement for two-way action respectively. third and fourth groups for the effect of slenderness ratio (λ) which decrease from (16 to 13.33), (13.33 to 11.43) and (16 to 11.43), The increase of final load is about 9.09 %, 12.5%, and 22.73% for one way and 6.12%, 9.62%, and 16.3% for two-way action respectively. Also when raised (λ) from (11.43 to 13.33), (13.33 to 16), and (11.43 to 16), the increase in lateral displacement is approximately (36.45%, 32.85%, and 81.28%) for one way action, and (36.76%, 25.29% and 71.35%) for two way action respectively.
