Generally, concrete columns consist of square, rectangular or circular cross sectional area. Columns are essentially required with the primary longitudinal reinforcement and lateral ties to avoid buckling of the primary bars. Basically there are two main types of columns called as short columns and slender columns. These can be model in FEM as frame elements.… Read More Basic Rules for RC Column Reinforcements
Here you can learn how to write a matlab code to calculate the local stiffness matrix. In meantime you will learn how to write a matlab code to solve problems related to spring elements.This is a basic code to understand the procedure. Everything has to start small :P. First we have to identify the inputs… Read More Matlab Coding for FEM Spring Element-Local Stiffness Matrix
Formulation of Spring Element Basically you know what is a spring. To model a spring in FEM it is best to use one dimensional spring element with 2 nodes as shown below. The element type is therefore is Linear Spring. 1 and 2 are the node numbersU1 is translation in x direction at node 1.U2… Read More Finite Element Analysis- Spring Element
FEM is a numerical method of solving engineering and mathematical problems.Stress Analysis for trusses,beams and other simple structures are carried out based on dramatic simplification and idealization. Types of Finite Elements 1-D Line Elements – Spring,truss,beam etc 2-D Plane Elements – plate , thin shell, thick shell, membrane etc 3-D Solid Elements – 3D quadratic… Read More Finite Element Method-Introduction
