When a cylindrical shaft is subjected to equal and opposite couples at the ends, either it will be in equilibrium or it will rotate at a uniform rate. In either case, it is subjected to torsion and the stresses ...

## Theory of Simple Bending

When a beam is subjected to a loading system or by a force couple acting on a plane passing through the axis, then the beam deforms. In simple terms, this axial deformation is called as bending of a beam. Due ...

## FLITCHED BEAMS

Beams that are built of more than one material are called composite beams. Examples are bimetallic beams, which consists of two different metals bonded together, sandwich beams, and reinforced concrete beams. Composite beams may be analysed by the same ...

## Determinate and Indeterminate Structures and Their DIfferences

Structure is generally classified into two categories as Determinate and Indeterminate Structures or Redundant Structures for analysis of structures to find forces based on criteria discussed below. Structure is an assemblage of a number of components like slabs, beams, ...

## MOMENT AREA METHOD

MOMENT AREA METHOD OF STRUCTURAL ANALYSIS: Theorem – I The change in slope between tangents drawn to the elastic curve at any two points A and B is equal to the product of and the area of the moment ...

## Prestressed Concrete- Advantages and Disadvantages

Prestressed concrete is the most durable, reliable and strongest concrete that is widely used for the construction of mega buildings and bridges. It is a type of concrete in which high-strength tendons placed in tension regions of the cross-section ...

## Pre-Tensioning and Post-Tensioning in Prestressed Concrete Design

The prestressed concrete design of a structure is influenced by either of the two processes, pre-tensioning, and post-tensioning. Pre-tensioning can be further classified into two categories such as linear pre-tensioning and circular pre-tensioning. Pre-Tensioning and Post-Tensioning in Prestressed Concrete ...

## MOMENT OF INERTIA CALCULATION FORMULA

What is Moment of Inertia? Moment of inertia, also called mass moment of inertia or the angular mass, (SI units kg m2) is a measure of an object’s resistance to changes in its rotation rate. It is the rotational ...
