What is a Fabsec beam?

A Fabsec beam is a cellular beam fabricated out of plate which has been analysed and designed within the FBEAM software and procured from one of our licensed fabricators.

How far can cellular beams span?

FABSEC® beams are used for primary and secondary floor beams and rafters can be composite or non-composite with typical floor spans of 8-24 metres and roof spans of up to 60 metres.

Why are castellated beams used?

The main use for castellated beams is to cover long distances while utilizing a lightweight section. In general, castellated beams are practical for spans over 30 feet in length. The long span capabilities of castellated beams allow for a more open floor plan.

Where are cellular beams used?

Cellular beams are often used to facilitate long spans resulting in flexible, column-free internal spaces, reduced substructure costs and shorter steel erection times. They can be made from rolled steel sections or fabricated from steel plate.

What are I beams made of?

I-Beams, also known as H-Beams have and I or H cross-section. I-Beams are commonly made of structural steel but can be formed out of aluminum. I-beams are most widely used in construction and can have an application for use in both beams as well as columns.

What are the advantages of cellular beams?

In terms of both construction and design, these beams are very versatile. They are very sturdy, offering stability and support for some of the largest construction projects. And the same time, they are surprisingly lightweight, making cellular beams easier to work with and easier to build a schedule around.

How far can an I beam span without support?

So, how far can a steel I-beam span? The distance an I beam can span is almost entirely reliant on the size of the beam. When it comes to residential projects like houses and smaller buildings, you can expect a steel beam to be eight inches wide. This allows it to span as much as 12 feet before you need another column.

How far can concrete span without support?

Reinforced concrete allows a wide range of structural options and provides cost-effective solutions for a multitude of situations—from residential buildings with moderate live loads and spans of about 25 ft, to commercial buildings with heavier live loads and spans ranging from 40 ft to 50 ft and beyond.

What are the advantages of castellated beams?

The primary advantage of castellated beams is the improved strength due to the increased depth of the section without any additional weight. However one consequence of the increased depth of the section is the development of stability problems during erection.

How does a castellated beam work?

A castellated beam is a beam that has a regular and repeating pattern of hexagonal holes. It is created by cutting the pattern lengthwise across two different halves, offsetting, and then welding them together to create a single expanded beam.

Can you drill a hole in an RSJ?

Drill a small hole first and then use a begger bit to drill bigger hole. Also remember by drilling through rsj you reduce the strength of it. Its the same if you drill holes in ceiling joists. If you are drilling a large hole you may seriously reduce its strength so may need to consult a structural engineer.

How big can a fabsec beam be for a roof?

FABSEC ® beams are used for primary and secondary floor beams and rafters can be composite or non-composite with typical floor spans of 8-24 metres and roof spans of up to 60 metres. FBEAM can design composite and non-composite plain and cellular beams, both normal and fire engineered.

Which is the best application for a fabsec beam?

The primary applications for FABSEC ® beams are for long span composite and non-composite construction, typical floor spans of 8-24 metres and roof spans up to 60 metres which give fewer columns offering flexibility and enhanced architectural freedom.

What can I do with the free fabsec software?

The Free software is typically used by Steel Designers to design primary and secondary floor beams and rafters for commercial multi storey construction projects.

What kind of Cellular beams can fbeam make?

FBEAM can design composite and non-composite plain and cellular beams, both normal and fire engineered.
