In the context of the continuous economic growth of the country, engineering project investment and construction are now transforming from rough to lean. It is urgent to optimize information technology, standardize project management mode, and improve project efficiency. At the same time, the integration of industrialization and informatization requires a deep combination, and the engineering field can exploit the pain points of project management, build an intelligent construction system, and drive the lean construction and management of engineering projects by data, on the one hand promoting the transformation and upgrading of the engineering industry to achieve smart and green sustainable development goals and on the other hand exploring smart city construction with engineering thinking to promote the healthy operation of cities. Taking the south extension of viaduct of Jinzhai Road in Hefei as an example, this paper combines BIM, Internet of Things, and other technologies to build a cloud platform-based prefabricated bridge project management system and promotes the promotion role of cloud computing, Internet of Things, BIM, and other information technologies on prefabricated bridge construction projects.

Investigating the seismic behavior of assembled concrete bridge piers is crucial in the design process due to the complex stress distribution in the connecting components. To demonstrate the seismic behavior of assembled concrete piers with hybrid joint connections, three bridge piers were designed with a scaling ratio of 1:8 and then tested under low cyclic loading conditions. The tests involved varying shapes of steel tube shear keys as parameters. The study involved examining failure modes and crack development, as well as analyzing the hysteretic performance, deformation capacity, energy dissipation, and stiffness degradation of the specimens. Furthermore, a finite element model was developed using ABAQUS, and the validity of the modeling approach suggested in this study was confirmed through experimental tests. The results indicate that the assembled piers exhibit reduced concrete damage at the joints. The enhanced strength of the joints is attributed to the incorporation of steel tube shear keys. The circular steel tube connection key integrated into the assembled bridge pier offers superior bearing capacity, energy dissipation, and stiffness degradation compared to the cross-shaped steel tube connection key. The presence of the built-in circular steel tube shear key in the assembled bridge pier suggests that it complies with the seismic structural measures, consistent with the design principle of "strong joint and weak member".

In order to accelerate the construction of bridge substructure, a socket joint construction that does not require interfaces roughening between the precast columns and the reserved cavity of the precast foundation is raised in this paper. The seismic performance of such fabricated bridge piers was investigated by carrying quasistatic tests on socket circular pier specimens of different embedment depths with a compared cast-in-place pier specimen. The experimental results showed that the prefabricated piers with the embedment length larger than 1.0 times the column diameter, featuring smooth interfaces that was free of roughening, had a failure mode of bending damage as well as the cast-in-place component. As the embedment depth increases, the seismic performance indexes of the socket bridge pier, including bearing capacity, ductility, and energy dissipation capacity, are improved. The seismic performance indexes of a socket bridge pier specimen with an embedment depth of 1.5 times the column’s diameter in the test are better than the cast-in-place one.
