Also when computers are used, matrix algebra is understanding of the structural behaviours. very convenient.

International Journal of Management, Technology And Engineering ISSN NO : 2249-7455 COMPRESSIVE STRENGTH BEHAVIOUR OF CONCRETE USING NANOSILICA(SiO2), NANO ALUMINA(Al2O3) & FERRIC OXIDE(Fe2O3) Abinaya Ishwarya G K1, G MadhanKumar2 1Assistant Professor, Department of Civil Engineering, Vels Institute of Science Technology & Advanced Studies, Chennai, Tamilnadu 2 Assistant Professor, Department of Mechanical Engineering, Thiruvalluvar college of Engineering and Technology, Vandavasi, Thiruvannamalai, Tamilnadu Abstract: The most active research areas dealing with cement and concrete understand of the hydration of cement particles and use of nano size ingredients such as nano silica, nano alumina, ferric oxide. If cement with nano size particles can be manufactured and processed, it will open up a large number of opportunities in the field of ceramics and high strength composites etc. The main objective of this paper is to outline some of the application of nanotechnology in concrete and comparing this concrete with ordinary concrete. Keyword: Compressive Strength, Tensile Strength, Flexural Strength, Nano alumina, Ferric oxide. I.INTRODUCTION I.1 GENERAL The main advances have been in the nano science of cementitious materials with an increase in the knowledge and understanding of basic phenomena in cement at the nano scale (e.g., structure and mechanical properties of the main hydrate phases, origins of cement cohesion, cement hydration, interfaces in concrete, and mechanisms of degradation). Recent strides in instrumentation for observation and measurement at the nano scale are providing a wealth of new and unprecedented information about concrete, some of which is confounding previous conventional thinking. Important earlier summaries and compilations of nanotechnology in construction can be found in this paper reviews the main developments in the field of nanotechnology and nano science research in concrete, along with their implications and key findings. -
Analysis of Statically Indeterminate Structures by Matrix Force Method
Module 2 Analysis of Statically Indeterminate Structures by the Matrix Force Method Version 2 CE IIT, Kharagpur Lesson 7 The Force Method of Analysis: An Introduction Version 2 CE IIT, Kharagpur Since twentieth century, indeterminate structures are being widely used for its obvious merits. It may be recalled that, in the case of indeterminate structures either the reactions or the internal forces cannot be determined from equations of statics alone. In such structures, the number of reactions or the number of internal forces exceeds the number of static equilibrium equations. In addition to equilibrium equations, compatibility equations are used to evaluate the unknown reactions and internal forces in statically indeterminate structure. In the analysis of indeterminate structure it is necessary to satisfy the equilibrium equations (implying that the structure is in equilibrium) compatibility equations (requirement if for assuring the continuity of the structure without any breaks) and force displacement equations (the way in which displacement are related to forces). We have two distinct method of analysis for statically indeterminate structure depending upon how the above equations are satisfied: 1. Force method of analysis (also known as flexibility method of analysis, method of consistent deformation, flexibility matrix method) 2. Displacement method of analysis (also known as stiffness matrix method). In the force method of analysis, primary unknown are forces. In this method compatibility equations are written for displacement and rotations (which are calculated by force displacement equations). Solving these equations, redundant forces are calculated. Once the redundant forces are calculated, the remaining reactions are evaluated by equations of equilibrium. In the displacement method of analysis, the primary unknowns are the displacements. -

Structural Analysis - III Introduction to Matrix Methods Module I Matrix analysis of structures • Definition of flexibility and stiffness influence coefficients – development of flexibility matrices by physical approach & energy principle. Flexibility method • Flexibility matrices for truss, beam and frame elements – load transformation matrix-development of total flexibility matrix of the structure –analysis of simple structures – plane truss, continuous beam and plane frame- nodal loads and element loads – lack of fit and temperature effects. 2 Force method and Displacement method • These methods are applicable to discretized structures of all types • Force method (Flexibility method) • Actions are the primary unknowns • Static indeterminacy: excess of unknown actions than the available number of equations of static equilibrium • Displacement method (Stiffness method) •Displacements of the joints are the primary unknowns •Kinematic indeterminacy: number of independent translations and rotations (the unknown joint displacements) • More suitable for computer programming Types of Framed Structures a. Beams: may support bending moment, shear force and axial force b. Plane trusses: hinge joints; In addition to axial forces, a member CAN have bending moments and shear forces if it has loads directly acting on them, in addition to joint loads c. Space trusses: hinge joints; any couple acting on a member should have moment vector perpendicular to the axis of the member, since a truss member is incapable of supporting a twisting moment d. Plane frames: Joints are rigid; all forces in the plane of the frame, all couples normal to the plane of the frame e. G rids: all forces normal to the plane of the grid, all couples in the plane of the grid (includes bending and torsion) f. -
