A bolt for a girder is a bolt that is cast in place with the cap. Therefore the bolt is concreted into the cap of the substructure of the bridge. The girder is then set on top of bearing pads, on top of the cap, in between the girder bolts. The bolts are there to keep the ends of the girders from moving side to side.

The answer is rivet.
Girder
Definition from China ZZHZ company Movable support system is a kind of construction machinery to install bridge girders by way of cast-in-place with its own formwork, supported by box girder. Bridge girder launcher realizes bridge construction if the girder carrier transports the prefabricated concrete girder to the rear part of the launcher. Difference between movable support system and bridge girder launcher 1. Without prefabricating concrete girder in the precast girder yard, the movable support system adopts cast-in-place and field maintenance. Averagely it finishes one piece of girder every 12 days. While for the bridge girder launcher, it needs to prefabricate concrete girder, then transport them to be installed on the bridge floor 2. The movable support system has a longer cycle to finish the project but with low investment and high benefit; the bridge girder launcher with a short completion time but high investment 3. With low investment and short preparation time, the movable support system can be fast put into use. While the bridge girder launcher needs a long time to prepare for other equipments such as girder carrier and gantry crane. 4. With less land occupation, the material cost of the movable support system is relatively low. 5. The movable support system is widely used in the mountain area that can not build large-sized precast girder yard, while the bridge girder launcher is popular in large-sized precast girder yard To sum up, it depends on the practical situation. But generally, the movable support system is more economical and more suitable for constrictive economy environment at present and in the future.
A "girder bolt"!
Rivet
girder is the main horizontal beam . the joists which are usually smaller, are connected to the girders and are supported by the girder.
That girder will be used for support.
beam girder
how do you calculate hogging of i girder
plate girder is a vertical section which supports the beam while gantry girder is a horizontal section which supports the othet small beams.
A building girder can be U shaped for several different reasons. The shape of the building girder will determine how much weight the girder can carry and how much side to side stress it can withstand.
Based on CMAA (Crane Manufacturers Association Of America) specifications, both single & double girder are equally rigid, strong & durable. This is because single girder cranes use much stronger cross girders than double girder cranes, and single girder cranes have lateral bracing, unlike double girder cranes.
