Practical Steps in Design of Concrete Buildings Concrete is arguably the most important building material which plays an important role in all building structures. Its virtue is its versatility which is its ability to be moulded to take any shape required for various structural forms. The entire process of structural planning and design requires not … Read more
Dynamic Analysis Methods for Seismic Bridge Design Depending on the seismic zone, geometry, and importance of the bridge, the following analysis methods may be used for seismic bridge design: The single-mode method (single-mode spectral and uniform-load analysis) assumes that seismic load can be considered as an equivalent static horizontal force applied to an individual frame … Read more
FINITE ELEMENT METHOD (FEM) Introduction: Finite Element Method (FEM) is nothing but a numerical technique to get the approximate solution to the boundary value problems consisting of a partial differential equation and the boundary conditions. The Finite element Method converts these typical equations into a set of algebraic equations which are easy to solve. Basic … Read more
State of stress at a Point (Stress Tensor) Consider a three dimensional body in equilibrium under the action of a set of external forces P1,P2,P3.. , the stresses developed in different planes vary. To study the magnitude of these forces at any point let the body be divided into 2 parts A&B by a cross … Read more
