4.4.7 Design of Hinged Line Rocker Steel Fabricated Bearings
We can also design the hinged line rocker steel fabricated bearings shown in
Figure 4.106
and detailed in
Figure 4.124
. The maximum vertical reaction at
the support of the main plate girder was previously calculated under dead
and live loads with dynamic effect (
R
D+L+
F
), which was 2193.36 kN.
