Being cost-effective, rapid construction, high transportability, and maintainability, post-tensioned precast concrete segmental bridges (PT-PCSBs) have been one of the most preferred choices for sites that are restrictive to access.

This chapter provides an overview on the state-of-the-art in prestressing systems for the structural retrofitting of reinforced concrete (RC) structures using Externally Bonded (EB) Fibre Reinforced Polymers (FRP). Focus is put on flexural strengthening, which currently is the most common application field for composite materials in structural ...

Soil Dynamics and Earthquake Engineering, 2019
Based on the principles of soil dynamics and structural dynamics, a ground motion analysis model of a slope reinforced by a frame with prestressed anchors is established, and the dynamic response of the reinforced slope under horizontal earthquake action

Loss of Prestress, Deflection, and Partial Prestress
1990This chapter includes discussions of several important, frequently encountered subjects that pertain to the elastic design of simple prestressed concrete flexural members. An engineer who frequently is engaged in the design of prestressed structures will become familiar with these relationships through design experience.

Applying Prestressed CFRP Sheets to Restore Prestress Losses in Prestressed Concrete Beams
SP-245: Case Histories and Use of FRP for Prestressing Applications, 2007This paper has described how the issue of the rehabilitation of damaged structures has attracted the attention of researchers in order to resolve the undesired problems caused by increased traffic loads, corrosion, or impact damage. Appropriate methods are therefore essential for extending the lifespan of the structures and the application of carbon ...

Redevelopment of Prestressing Force in Severed Prestressed Strands
Journal of Bridge Engineering, 2011The flexural capacity rating of prestressed girders having severed or corroded strands often progresses by simply neglecting the contribution of the affected strands from the girder section and assessing the capacity. While this is an adequate approach at the affected section, it is conservative elsewhere along the span, assuming that fully bonded ...

Journal of the Korea Concrete Institute, 2004
This study deals with literature review, developing a predicting equation for the ultimate stress of internal and external prestressing steel, and an experimental test with the parameters affecting the ultimate stress of prestressing steel in prestressed concrete beams strengthened by external prestressing tendons.

Soft Matter, 2019
Living cells exhibit a complex mechanical behavior, whose underlying mechanisms are still largely unknown. Emerging from the molecular structure and dynamics of the cytoskeleton, the mechanical behavior comprises "passive" viscoelastic material ...

Composite structures, 2019
The effect of prestress on the ballistic performance of bi-layer ceramic composite armors was explored both experimentally and numerically. Three types of target plate with different prestress levels were prepared using the method of shrink-fit, and ...
