Flush end-plate beam-to-column joints often subjected to a combination of bending
and axial forces .The level of axial forces in the joint may be significant in case of: sway
frames under horizontal loads, pitched roof portal frames and irregular f
rames.. Many of
design codes neglect the effect of axial force in the connection analysis as it is usually low.
Eurocode 3 limits the axial force acting on the joint to 10% of the design plastic resistance
of the connected member cross section to apply component method.
The objective of this paper is to discuss the behavior of flushend-plate connections
under a combination of bending and axial tension or compression forces For the nonlinear
finite element analysis the modeling process was carried out using CATIA computer
program. The results of the finite element analysis of the connection showed that by
applying the tensile axial load of the beam into the connection, the ultimate bending
capacity of the connection will decrease. On the other hand, by applying compressive axial
load of the beam to the connection, the ultimate bending capacity of the connection will
increase at first; but after the buckling of the compressive flange of the beam takes place,
the total capacity of the connection tends to decrease.
