Re: base plate bending

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Rauf,

Eurocode 3 is based on elastic analysis in this case (hence bt2/6, which is the elastic section modulus, S, for a rectangle); AISC-LRFD uses plastic (i.e. limit state) analysis, hence bt2/4 (which is the plastic section modulus, Z, for a rectangle). In my opinion, elastic analysis of base plates (and for all connections, for that matter) is grossly conservative, if not to say wrong.

dear sirs

while eurocode 3 uses w=b.t2/6 for base plates,lrfd uses w=b.t2/4. both follow load resistance factor design procedures.
your valuable comments are wellcome.
