STRUCTURAL ANALYSIS 2 | CIVIL ENGINEERING

24/06/2017· CIVIL_ENGINEERING. Introduction: In engineering, an influence line graphs the variation of a function (such as the shear felt in a structure member) at a specific point on a beam or truss caused by a unit load placed at any point along the structure.Some of the common functions studied with influence lines include reactions (the forces that the structure's supports must apply in order for

Concrete Admixtures (Additives)- Types, Selection

Concrete additives are used to achieve desired workability in case of low water cement ratio, and to enhance setting time of concrete for long distance transportation of concrete. So, it is of much importance for a civil site engineer to know about the types of admixtures (additives) and their properties for better selection and application in concrete works.
