Effective Length of I-Beam
Effective Length of I-Beam
(OP)
Hi,
I have a steel I-Beam supporting a roof, as per attached detail.
The beam sits on a 100mm inner blockwork leaf at wallplate level. The clear span of the UB is 7m.
My question is can I take the effective length of the beam as 1m as it is laterally restrained by roof structure?
Also do I need to be concerned about destabilising loads?
John.

Not sure what you mean by this. Can you elaborate?
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Is the beam laterally restraining the block work wall panel under?
The roof is noted as being laterally restrained. How is this achieved, bracing in the roof plane or otherwise? The detail shown in the sketch by itself is not sufficient to provide lateral restraint, although the roof is generally sufficiently braced to transfer the lateral loads.
