Adaptively prestressed concrete structures
… Truly adaptive civil structures do not exist. Concrete structures can be made adaptive through variable prestressing. Design concepts for an adaptive prestressed concrete girder are formulated in this research. Loading conditions and desired capabilities of the proposed system are defined. The …

Fiber glass prestressed concrete
The use of glass reinforcement in concrete was conceived over thirty years ago. However, it has been within the past ten years that the advantages of glass fiber over steel for use in prestressing have become known. Past research shows that, even though the physical properties of glass fiber in the …

Partially prestressed concrete internal square panel
… three series of ten tests of 1.5m span partially prestressed panel with typical span to depth ratio, levels of loading, levels of prestress and geometry of tendon profiles. The models were fixed along the edges to simulate the continuity of an internal panel in a multi-panel slab system. …

CFRP Prestressed Concrete Exposed to Moisture
… matrix-dominated changes to the CFRP-concrete bond when the CFRP rods are cast into concrete as prestressed reinforcement. Experiments were conducted to measure the transverse swelling and moisture uptake rates of stressed and unstressed CFRP rods immersed in water and concrete pore …

Flexural behavior of prestressed concrete monoblock crossties
As the use of concrete crossties increases for heavy-haul freight railroad lines in North America, it is becoming more critical to improve the understanding of their flexural behavior. This improved understanding can help to optimize current design and maintenance practices for concrete crossties, …

Lifting Analysis of Precast Prestressed Concrete Beams
… are performed to investigate the behavior of concrete beams during lifting and to validate the proposed method. Additionally, a statistical characterization of beam imperfections is presented, based on recently conducted field measurements of beam lateral sweep and eccentricity of lift …

Time-dependent losses in post-tensioned prestressed concrete
… losses and deflections of Class 1 uncracked prestressed concrete beams. The main influencing factors considered were environmental conditions, loading conditions,size and shape of members and concrete mix composition. Twenty seven beams consisting of both I- and rectangular sections with …

Structural Condition Assessment Of Prestressed Concrete Transit Guideways
… system is composed of six-span continuous prestressed concrete bridge segments. The overall transit system incorporates a number of continuous bridges which share common design details, geometries, and loading conditions. The original analysis is based on certain simplifying assumptions …

Bond strength history in prestressed concrete reactor vessels
… has been made to study bond strength history in Prestressed Concrete Reactor Vessels (PCRV) which house the Advanced Gas-cooled Reactors. Three-dimensional non-linear analytical model has been developed in which the effect of bond is included. A finite element computer program is written in which …

Response of Prestressed Concrete Plate-Edge Column Connections
… experimentally the strength and behavior of prestressed plate-edge column connections with unbonded tendons representative of those used in prestressed flat plate buildings. To achieve the objective, four two-thirds scale, flat plate-edge column specimens were constructed and subjected to …

Time-Dependent Deformations in Segmental Prestressed Concrete Bridges
… the time-dependent behavior of segmental prestressed concrete bridges built by the cantilever method was presented. This analytical procedure was aimed specifically at those bridges where segments are precast and adjacent cantilevers are made continuous. It was based on a step-by-step …
