That depends on what the beam is supporting above.
Ideally 150mm bearing is the minimum. I have seen as little as 50mm! But any engineer would frown upon this.
it will need a suppot element , depper and stiffer concrete members will act as support
Depends on the dimensions of the beam. length * width * height
Unbraced length in a beam refers to the distance between points where the beam is laterally supported or braced against buckling. It is a critical parameter in structural engineering, as it influences the beam's stability and load-carrying capacity. The longer the unbraced length, the greater the risk of lateral-torsional buckling, which can affect the design and safety of the structure. Proper bracing strategies are essential to minimize this length and ensure structural integrity.
With a span of only 8" you can probably use a wood beam, but without a set of plans no one can accurately answer your question.
to help support the building. also to build up the building bigger or taller depending on the size of the beam.
beam for sr20det?
It is the length of the main bar provided at the column beam junction or column footing junction to allow for the development of stresses to its design strength.
You need at least 50 square inches of bearing (at least 2x6 wall for a 10" wide beam). You also have to make sure to have proper pad below and enough studs (of filled cells) in the wall to accomodate the load.

the efffective length of a beam is the length along the beam at which the beam will fail when a load is acting upon it. This effective length is usually near the centre of the beam as that is where the stresses are the greatest. For example a fat chick jumping up and down on the beam would reduce the effective length dramatically as the loads are semi-constant but ginormous.
Deflection of beam depends upon load and length of beam. Larger the beam, larger will be it's selfweight
The length is "stem to stern" or "bow to transom", and the width is "beam to beam".
1.50 meter from the support is the max. safe length cantilever beam
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
Depends on the dimensions of the beam. length * width * height
A beam that has the same porperties along its entire length.
The most accurate and reliable method to calculate the load-bearing capacity of a beam using an LVL beam calculator is to input the specific dimensions and properties of the beam, along with the load and support conditions, into the calculator. This will provide a precise estimation of the beam's capacity to support weight.
