Types Of Beam | Classification Of Beam Used For Construction

A beam is a structural member used for bearing loads. It is typically used for resisting vertical loads, shear forces and bending moments.

Types of Beams:

Beams can be classified into many types based on three main criteria. They are as follows:

1. Based on equilibrium conditions:

Statically determinate beam –For a statically determinate beam, equilibrium conditions alone can be used to solve reactions.
Statically indeterminate beam– For a statically indeterminate beam, equilibrium conditions are not enough to solve reactions. Additional deflections are needed to solve reactions.

2. Based on the shape of cross section:

I-beam –光束与“我”横截面
T-beam –Beam with ‘T’ cross section
C-梁 -Beam with ‘C’ cross section

3. Based on geometry:

Straight beam –Beam with straight profile
Curved beam –Beam with curved profile
Tapered beam –Beam with tapered cross section

4. Based on the type of support:

1. Simply supported beam:
简单地支撑的光束是一种梁，其在另一端在一端和滚子支撑件处固定支撑。取决于所施加的负荷，它经历剪切和弯曲。它是存在中最简单的结构元素之一。

2. Cantilever beam:

A cantilever beam is fixed at one end and free at other end. It can be seen in the image below.

3. Overhanging beam:
A overhanging beam is a beam that has one or both end portions extending beyond its supports. It may have any number of supports. If viewed in a different perspective, it appears as if it is has the features of simply supported beam and cantilever beam.

4. Continuous beam:
A continuous beam has more than two supports distributed throughout its length. It can be understood well from the image below.

5. Fixed beam:
As the name suggests, fixed beam is a type of beam whose both ends are fixed

6.trussed -a beam strengthened by adding a cable or rod to form a truss.
