Authors - C. Manikandan, S. Arivalagan, A. Arivumangai Abstract : Reinforced concrete columns are main load bearing members in any type of structure, which contribute lateral stiffness also. There are two types of reinforcements in a column means longitudinal and transverse reinforcements. Longitudinal reinforcements are provided parallel to the longitudinal axis of column and transverse reinforcements may be hoop, ties or spirals. Stress-strain behaviour of column is important in order to find out the available ductility from a column by moment curvature analysis. This paper presents analytical study on stress-strain behaviour of reinforced concrete column by modelling concrete and steel part separately. A new finite element software Calculix and ANSYS software are used for the analysis. The results were validated using the available experimental data.
Authors - C.N. Rajesh, T. Felix Kala, M. Narmatha Abstract : Slope stability of embankments on soft soils can be enhanced by providing basal reinforcement with geosynthetics proved by many researchers. In the literature the stability of the slopes analyzed by considering horizontal axial pullout force in the reinforcement upon with full mobilization of frictional resistances on the surface of the reinforcement layer. But during the failure the reinforcement layer is pulled by the sliding mass is observed to be inclined not in horizontal. During the failure transverse deformation will occur at the intersection point of failure wedge with reinforcement layer. The amount of transverse displacement depends on the angle of rotation of the sliding mass at the center of the failure circle. Hence in this paper stability of a basal reinforced embankment by considering the geometry of the reinforcement during the failure.
Authors - R. Chandrasekaran, S. Nallusamy Abstract : In current scenario, production sector is the back bone of economy of any country and it is mandatory for the manufacturing organizations to control the cost as they do not have the control over the price. To minimize the cost, it is required to reduce the defect rate. Six sigma quality management systems is a customer-focused and data-driven quality strategy that provides a clear roadmap for organizations to deliver nearly perfect products and services. On the other hand, value engineering has for its purpose the efficient identification of unnecessary cost. It focuses the objective of equivalent performance at lower cost. This paper presents the application of six sigma approach combined with value engineering methodology to reduce process variability in a medium scale manufacturing industry with cost-effective manner.
