BEHAVIOR OF REINFORCEMENT BARS IN FOUNDATION WITH SOIL TO SATISFY SUSTAINABILITY

Abstract

This study presents the behavior of using many types of reinforcement with slab foundations to satisfy sustainability. This foundation with soil effect and two types of bar reinforcement (steel bars and geogrid) are taken. Nonlinear analysis is used with the theoretical model by finite element program software ABAQUS to represent the many types of reinforced concrete foundations with both unsaturated and saturated soil with the effect of loading. Effect of load-displacement-relationships with many cases which were taken for this study such as the geogrid and steel bar ratio in reinforcement of foundation with unsaturated and saturated soil. From this study, it is shown that reinforcement by geogrid increased the strength of the member or the foundation when taken with different ratios of reinforcement by steel bars and get the best sustainable way or solution by decreasing the reinforcement by steel. The ratio of geogrid is 40% to 20 % from total reinforcement, while the required member or foundation in the case of soil, which is unsaturated, is more strength than it is in the case of saturated soil.
