Figure 10.35 Floor beams and bottom lateral bracings of Shang Xin Bridge.
lateral sway bracings for wind (as shown in Figure 10.34a and c) are pro-
vided only at the two highest posts at pier locations. Panel members are
all made of tube sections, and they are semirigidly connected as shown
in Figure 10.36. The trusses are supported by temporary supports under-
neath and launched forward as shown in Figure 10.36. There are 25 trian-
gular panels with each of them as one erection unit.
Finite element models were generated with MIDAS Civil (Figure 10.37a)
and ANSYS (Figure 10.37b) for cross-checking the simulation of all
