What is unbraced length in a beam?

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.


What are the failure modes of restrained steel beams under fire?

you may have 2 kinds of failures. there is the buckling and the bending. in the bending there is compression and tension, while in the buckling there i torsion and shear. if the beam is restrained but not stiffened you may have Lateral Torsional Buckling, but if it is restrained and stiffened throughout, then you will have Tension Field Action and this would result in a higher load durability.


How do strengthen a vertical support beam therefore eliminating the Horizontal support beam?

I would imagine increasing the "chunkiness" of the vertical member would help protect against buckling but in real life scenarios, loads are imperfectly applied and horizontal forces will happen inescapably.


How do you check stiffness of concrete beam?

Why column is tied to beam?

If Ly/Lx >12 then the column is said to be long column where Ly is the length of column and Lx is cross sectional dimension (B or D) Long column has reduction factor and it frequently failed under local buckling. so introducing a beam at least every floor level, the column design/act as a short column..column stiffness also increased tieing with the beam..

1991 Buick has no high beam?

check the fuses then check high/low beam switch


What is buckling factor?

it is the ratio of buckling load to applied load


Low beams not working?

Check the low beam bulbs to insure that they have not burned out. Check for a low beam fuse, then check to see if the dimmer switch is bad.
