“…The other comparative parameters were base shear and the natural time period and concluded higher for PSC box type superstructure. Another comparative parameter of fundamental frequency and mode shapes for the 3d model structure using SAP 2000 with the experiment performed on the construction site on PSC I-girder [3][4]. The Precast test beam modelled in the 3D software analyzed and checked for the mechanical properties of the concrete sections related to the vibration stress, structural behaviour and crack opening at the joints considering geometric and material nonlinearity [5].…”

In recent trends of infrastructure development, the demand for the construction of highway bridges has increased in urban cities. The demand for inter-city and intra-city road transportation has also increased exponentially. The major hindrance that occurs is the lack of availability of land space in highly crowded urban cities. To fulfil the needs of increasing traffic conditions in the recent urbanization, An innovative idea is needed to fulfil the high demands of transportation in the development. To reduce the traffic congestion and to increase the speed of the vehicles and thereby reduce the travel time requires elevated corridors for better connectivity. One such innovative design includes prestressed segmental concrete bridges over conventionally adopted I-girder-type bridges. This paper discusses the advantages of the PSC segmental bridges over the conventionally adopted I-girder type bridges from all aspects whether it’s the cost of construction or the quantity of the resource consumption segmental bridges have numerous advantages like a six-lane flyover can be accommodated on a single pier instead of twin/multiple piers which requires major space under the superstructure. Nowadays, The National Highway Authority of India (NHAI) and Ministry of Road Transport and Highways (MoRTH) specifically mention their demands for the construction of PSC-type structures in urban cities due to lack of encroachments. This paper also discusses the analysis and design of the Spine and Wing type super-structure along with its construction feasibility, cost cuttings, and speedy constructions. The paper concludes on the basis of a comparison that the average cost involved in the construction of conventional I-Girder systems is 18% higher than that for the PSC Segmental Type superstructure. The Resource consumption is also 25% higher in the case of the I-girder systems over the PSC Segmental Type systems.

This paper presents a multi-functional strand capable of introducing prestressing force in prestressed concrete (PSC) girders and sensing their static and dynamic behavior as well. This innovative strand is developed by replacing the core steel wire of the strand used in PSC structures with a carbon fiber-reinforced polymer (CFRP) wire with a built-in optical Fiber Bragg Grating (FBG) sensor. A full-scale girder specimen was fabricated by applying this multi-function strand to check the possibility of tracking the change of prestressing force at each construction stage. Moreover, dynamic data could be secured during dynamic loading tests without installing accelerometers and made it possible to obtain the natural frequencies of the structure. The results verified the capability to effectively manage the prestressing force in the PSC bridge structure by applying the PC strand with a built-in optical sensor known for its outstanding practicability and durability.
