A ship’s ladder. Used where every bit of space counts. One World Trade Center in New York cost about $4 billion to build. By contrast, the floating USS Gerald Ford cost $13 billion. Shipbuilders understand space like no other trade does because it’s so expensive. And not just expensive in dollars. Space taken up by… Read More Type of staircases take up the least space in a building and easiest to build
A borderless pool has water overflowing around the entire perimeter. The water is usually captured in a gutter and then sent to a tank. The tank is called a surge tank. A pump moves the water from the tank back to the pool. infinity pool have become quite popular not only on rooftops, but also… Read More vanishing edge pool or infinity pool
Let’s understand the role of a structural engineer. Basically structural engineering deals with the analysis and design of structures. A Structure can be defined as an assembly of various components that act together under “stress” conditions. Bridges, highways, buildings, transmission towers, trusses, water tanks, offshore structures, are some common structures in today. The basic purpose… Read More ROLE OF A STRUCTURAL ENGINEER
Welcome to my blog. This is a blog made to share every theoretical and practical aspects of engineering from basics to advance. Here you will be able to understand the basis of engineering, the evolution of engineering, theoretical background and how we are using engineering in the field in today. Engineers provide solutions to world.… Read More BEGIN YOUR JOURNEY AS A STRUCTURAL ENGINEER
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
Introduction Seismic analysis is a subset of structural analysis and is the calculation of response of a building structure to earthquake. In usual case normal buildings less than 3 stories doesn’t require earthquake analysis (except japan). Engineer know that everything has a natural frequency. A building also has a natural frequency and this is belong… Read More Earthquake/Seismic Analysis
A building is set out in order to clearly define the outline of the excavation and the centre line of the walls, so that construction can be carried out exactly according to the plan. The centre line method of setting out is generally preferred and adopted. 1. From the plan (fig 1), the centre line… Read More Procedure for Setting Out a Building Plan on Ground
