Stiffness and Strength are basic terms in structural engineering. One might feel they are similar but they have certain differences. And these differences are key in understanding these terms. It is safe to assume that Stiffness and Strength mostly govern Structural Engineering. All of Structural Engineering can be taught, in one way or another, based …
WHAT IS MOMENT OF INERTIA? Inertia is a property of a body under which it continues to be in a state of rest or uniform motion until it is acted upon by an external force.
Elastic Constants are the constants that express the elastic behaviour of a given material. There are three elastic constants. 1. Young’s Modulus 2. Shear Modulus 3. Bulk Modulus Sometimes, people add Poisson’s ratio to the list thereby making it Four Elastic Constants. We have already learnt about Young’s Modulus and its significance in one of …
Similar to Young’s Modulus, Poisson’s Ratio is a material specific and independent constant. It describes how different materials deforms under loading. Before we learn about Poisson’s ratio, let us learn about types of Strains. TYPES OF STRAINS We gave an overview of Strain in our previous post. To revise pretty quickly, Strain is a dimensionless …
Retaining wall is a structure which is used to retain or hold back any material, usually soil, and prevent it from sliding away. In this post, we shall see about the various components and types of retaining wall and their behaviour and type of loads on retaining wall. TYPES OF RETAINING WALL The retaining walls …
Before we learn about the significance of Young’s Modulus, let us ask ourselves, why should we learn about material properties and what is the importance of that in design and analysis? Quick answer: Behaviour of various materials is different in different loads. For example, concrete performs well in Compression but it is very poor under …
A beam is a horizontal structural element that is capable of withstanding load by resisting bending. Hence, beams are flexural members, therefore, Bending Strength or flexural strength, which is a product of Young’s modulus (E) and Moment of Inertia (I) is an important parameter for beams. Behaviour of the beam is primarily observed by deflection …
