Experimental Behavior of the Curved Continuous Twin I-Girder Composite Bridge with a Precast Concrete Slab Subjected to Bending, Shear, and Torsion

Table 4

Construction sequence of the bridge model and prototype bridge.

Construction sequence	Prototype bridge	Bridge model
Step 1	Lifting the first span steel main girder (40 m)	Lifting the first span steel main girder (8 m) and hanging weight compensation sandbags
Step 2	Lifting the second span steel main girder (30 m) and welding two-span girder together	Lifting the second span steel main girder (6 m), hanging weight compensation sandbags, and welding two-span girder together
Step 3	Installing precast concrete slabs in sequence	Installing precast concrete slabs in sequence and hanging weight compensation sandbags
Step 4	Pouring concrete in the shear pocket and transverse joints	Pouring concrete in the shear pocket and transverse wet joints
Step 5	Completing the deck pavement	Loading pavement weight sandbags
