Abstract: Many studies were made in the recent years related to analysis the toughness behavior of fibre reinforced concrete under impact loading condition. This study focus on the investigation of hybrid fibre reinforced concrete using polypropylene fibre and steel fibre unde impact loading. The concrete mixes were arrived based on the packing density of the aggregates. Three mixes were arrived having the combination of polypropylene fibre (PP) and steel fibre (SF) in varying proportions with different aspect ratio. The experimental set was made as per Indian Standards. The test results evidently shows the combination of 50% of 60mm steel fibres and 50% of 35mm steel fibres has recorded highest toughness value under impact. Correspondingly the other hybrid combination of polypropylene and steel fibres has also exhibited a higher value than the plain concrete. This study shows a comparative study on the behavior of hybrid fibre concrete to the plain concrete under impact loading condition.

Abstract: The technique of reinforcing soil for foundation improvement is well established. In this paper, parametric study using finite element analysis PLAXIS, 8.2 has been introduced to discuss the effect of elastic modulus of clay on settlement in clay beneath center and corner of strip footing at thickness 0.3 and 1.5 m without geogrid layer. Secondly case study the effect of elastic modulus of sand, elastic modulus of clay, and thickness of strip footing on relative settlement Ss-c/Sc (settlement in sand overlay clay over settlement in clayey soil) beneath center and corner of strip footing without geogrid. Third case study the effect of one layer geogrid depth and thickness of strip footing on relative settlement beneath center and corner of strip footing. The results indicated that increasing elastic modulus of clay decreases settlement beneath center and corner of strip footing without geogrid. The settlement in case of sand overlay clay beneath center and corner of strip footing withou
