# Types Of Loads In Beam

## Table of Contents

Types of loads in beam transfer all the loads (Dead load and live loads) including their self-weight to the columns or wall. The loads from the columns or walls are transmitted to the foundation. From the foundation, the load is safely transferred to the soil.

- Point load or Concentrated load
- Uniformly Distributed Loads (U.D.L.)
- Uniformly Varying Loads (U.V.L.)
- Arbitrary Loading

### 1. Point load or Concentrated load

A concentrated load is a single-point load acting on the beam in a particular area. weather, center, etc, Examples; Secondary beam, cross wall, column.

Point loads, sometimes referred to as concentrated loads, are forces exerted at particular locations on structural elements like beams and slabs. A point load is localized at a single point, as opposed to uniformly distributed loads or uniformly varied loads, which are dispersed over an area or the length of an element. In structural analysis and design, point loads are crucial factors to take into account, particularly when simulating situations in real life.

### 2. Uniformly Distributed Loads (U.D.L.).

A uniformly distributed load is, the load is acting on the beam on the entire length evenly. For example; wall load.

A load given to a structural member, like a beam, that is uniformly distributed along its whole length is known as a uniformly distributed load (UDL). In engineering analysis and design, this kind of load is frequently employed to mimic scenarios in which a constant force per unit length acts across the beam span.

A variety of engineering applications involve uniformly distributed loads, such as the weight of objects being stored on a shelf or the pressure exerted by a fluid on a horizontal surface. To make sure that the structure can safely take the applied loads without failing, engineers employ these loads in structural analysis to find the internal forces, stresses, and deflections in the beam. The equilibrium and behavior of the structure under the impact of UDLs and other types of loads are evaluated using the concepts of statics and structural analysis.

### 3. Uniformly Varying Loads (U.V.L.)

A uniformly varying load is, the load acting on the beam on the entire length in inclined. For example; an inclined roof.

A triangle load, often referred to as a uniformly varying load (U.V.L.), is a kind of load that varies linearly throughout the length of a structural member, like a beam. A Uniformly Distributed Load (UDL) has monotonic intensity across the span, whereas a U.V.L. exhibits varying magnitudes from one end of the beam to the other.

### 4. Arbitrary Loading

An arbitrary load is, the load acting on the beam on the entire length is not evenly.

A load applied to a structural element, such as a beam or structure, that deviates from a straightforward or standard distribution pattern is referred to as arbitrary loading. In contrast, to preset load types such as uniformly distributed loads (UDL), uniformly varying loads (U.V.L. ), or other load types, arbitrary loading is not limited by any particular shape and can vary in length and distribution along the element.

Complex real-world situations where forces or loads are applied irregularly or non-uniformly might give rise to arbitrary loads. These loads could be the consequence of external variables like shifting locations of equipment, unevenly dispersed live loads or other dynamic forces.

## Simply Supported Beam

It is a beam supported freely at the two ends of walls or columns. In actual practice, no beam rests freely on the supports (walls or columns) without fixing the supports. The moment is not induced at the supports, since it allows rotation. Hence, no beam is practically simply supported.

A common structural part that is supported at both ends and has unrestricted rotation and deflection under load is called a simply supported beam. It is among the most basic and common kinds of beams used in structural engineering. “Simply supported” means that there are no restrictions preventing rotation at either end of the beam’s support.

Different kinds of loads, such as distributed or point loads, can be used on a simply supported beam. Point loads in a simply supported beam are usually assessed as follows.

An application of a point load at the center of the span is a typical situation for a simply supported beam. This indicates that the load is delivered precisely in the middle of the supports.

## Cantilever Beam

When a beam is fixed in a wall or column at one end and the other end is free, it’s called a cantilever beam. It has a tension zone on the top side and a compression zone on the bottom side. It is used to support slabs projecting outside the wall/column. Example: Portico, Balcony, etc.

A structural element known as a cantilever beam has support at one end and extends horizontally without support at the other. This kind of beam is frequently utilized in many technical applications, including platforms, buildings, and bridges. Understanding how a cantilever beam responds to outside forces which can have an impact on both the vertical and rotational equilibrium is essential to analyzing point loads in the beam.

When a point load is applied to a cantilever beam, the following factors need to be taken into account: Applying Point Load at the Free End. Although point loads can be applied at various points along the cantilever beam’s length, applying a point load at the free end is a typical situation.

## Overhanging Beam

In an overhanging beam, its end extends beyond the wall or column support. Overhanging the beam is the unsupported portion of the beam. It may be one side or both sides of the support.

A structural element that protrudes past its supports on one or both ends is known as an overhanging beam. An overhanging beam, in contrast to a simply supported or cantilever beam, has parts that extend past the points of support. This extension may take place on one or both of the supports’ sides.

Shear pressures, bending moments, deflections, and the impact of outside forces on the beam’s responses are all taken into account while analyzing point loads in an overhanging beam. Here are some important things to remember.

A point load applied at any position along the beam’s length, including the overhanging section, is a typical case in an overhanging beam.

It is necessary to compute the reactions at the supports while accounting for the imposed point load.

## Fixed Beam

In this beam, both the ends of the beam are rigidly fixed to the supports (walls or columns). Also, main reinforcement bars and stirrups (in the form of rectangular rings) are provided. Here, Bending is constrained at the supports. A moment is induced at the supports since it will not allow rotation.

A fixed beam is a structural element that is supported at both ends and restricted from rotating at those ends. It is sometimes referred to as a fixed-ended beam or a built-in beam. A fixed beam has its ends permanently fastened to another beam or integrated into a support structure, limiting any movement at those places, in contrast to a simply supported beam, where the ends are free to spin.

Shear pressures, bending moments, deflections, and the impact of external forces on the beam’s responses are all taken into account while analyzing point loads in a stationary beam.

Anywhere along the fixed beam’s length, a point load can be applied to change the internal forces and moments within the structure.

## Continuous Beam

A continuous beam is supported on more than two supports this beam is more economical for any span length. This beam is commonly and most used compared to all types of beams.

A continuous beam is a structural component that has more than two points of support along its length and spans over many supports. A continuous beam includes supports at several locations, forming a continuous system of spans, in contrast to simply supported or cantilever beams, which have supports at their ends. When greater spans are needed, continuous beams are frequently utilized in the construction of buildings, bridges, and other structures.

Shear pressures, bending moments, deflections, and the impact of outside forces on the beam’s responses are all taken into account while analyzing point loads in a continuous beam. Here are some important things to think about A point load can be applied to a continuous beam at any point along its

length, influencing the internal forces and moments that exist throughout the beam.
