What is a cross section beam?

The cross section of a beam has a significant effect on how easily the beam will deform. For example, everyday experience tells us that a flat metal ruler will flex much more easily than a piece of metal tubing with walls of the same thickness.

What is a hollow section?

A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology.

Which section is better for beam?

Considering same weight sections and same material beam means the cross section are is same for all and hence for axial load purpose all sections are equally effective.

Can a beam be hollow?

The solid beams were designed as hollow ones assuming that the torsion is resisted by the outer 50 mm thickness. From their results, it could be seen that both solid and hollow beams with pure torsion failed approximately 10% below the design loads, and those with dominant bending failed above the design loads.

What is RHS and SHS?

The term RHS stands for Rectangular Hollow Section. RHS is the most prevalent term and is generally accepted for describing square hollow section as well, which is technically incorrect. The correct term for square tube is SHS which stands for Square Hollow Section.

What is CHS in construction?

Circular hollow sections (CHS) was the first form of hollow section. Commonly used in a wide range of structural, mechanical and construction areas.

Why are I section beams used?

I beams are the choice shape for structural steel builds because of their high functionality. The shape of I beams makes them excellent for unidirectional bending parallel to the web. The horizontal flanges resist the bending movement, while the web resists the shear stress.

Are steel beams Hollow?

Steel hollow sections are commonly used in welded frames, columns and as beams providing various benefits to a range of construction and mechanical applications.

What is HSS column?

Hollow Structural Sections (HSS) columns are prevalent in many types of construction, especially in common cases such as low-rise retail buildings. In reality, HSS columns can be a great option for taller buildings as well with its aesthetically pleasing shape, simple framing connections and small footprint.

What is the best shape of beam?

The most efficient shape for both directions in 2D is a box (a square shell); the most efficient shape for bending in any direction, however, is a cylindrical shell or tube. For unidirectional bending, the I or wide flange beam is superior.

What is a hollow structural section?

A hollow structural section ( HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology.

What is the reference standard for dimensions of hot finished hollow sections?

The reference standard for the dimensions of hot finished hollow sections is EN 10210 – Hot finished hollow sections of non-alloy and fine grain structural steel. Section properties have been taken from publication P363 (see Bibliography). 1.4.3 Axis Notation

What are encased beams?

Encased beams have been used as rigid reinforcement in deck bridges for several decades. Nowadays they are used mainly in railway reconstruction with limited building heights. During the entire period of their exploitation there have not been any changes or modifications in design or structural solution.

Can I use a HSS as a beam?

HSS can also be used as beams, although wide flange or I-beam shapes are in many cases a more efficient structural shape for this application. However, the HSS has superior resistance to lateral torsional buckling .
