Adaptively prestressed concrete structures
… 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 system architecture is composed of sensors, a monitoring and control scheme, and actuators. These system …

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
… 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 solution (CPS). CFRP rods were also embedded in concrete and …

Self-Compacting Concrete for Prestressed Bridge Girders
… materials for the construction of precast prestressed SCC girders in the State of Minnesota. The primary objective of the research was to determine both short-term and long-term properties of SCC bridge girders, evaluate the applicability and accuracy of available test procedures, design …

Dislocations and Green's functions in prestressed solids
… deformation of an incompressible, anisotropic, prestressed body. These functions, given by Bigoni and Capuani, show the response of an infinite body to a concentrated force. The effect of prestress on dislocation (and inclusion) fields in non-linear elastic solids is analyzed by extending …

Flexural behavior of prestressed concrete monoblock crossties
… current design and maintenance practices for prestressed concrete crossties are presented. To measure the bending moments and support conditions experienced in North American heavy-haul freight service, surface strain gauges were mounted to ten concrete crossties along a high-tonnage, …

Prestressed cable domes: structural behavior and design
… principle. They rely on the assembly of prestressed cables in equilibrium with vertical struts. Members are stressed purely in axial tension or compression and as a consequence, the materials are used efficiently. Not much has been written about the structural design of cable domes. This …

Design of prestressed, fabric-formed concrete beams
… feasibility and performance of fabric formed, prestressed beams with a keyhole cross-section, while varying parameters such as concrete strength, loading, beam depth, and prestressing force. They are designed for flexure via a sectional method, starting with the critical midspan section, and …

Lifting Analysis of Precast Prestressed Concrete Beams
… numerical examples for two typical precast prestressed concrete beam cross-sections are included to demonstrate the proposed method.
-
The design of prestressed composite steel bridges
… the introduction of two new structural systems: prestressed concrete and composite design. Each of these new construction methods has advantages and limitations. A new idea of combining these two structural systems into one could result in more economical structures particularly suited for long …

Capacity of concrete beams prestressed with BFRP tendons
Steinsteypt mannvirki eru yfirleitt járnbent vegna lágs togstyrks steypunnar. Járnbending hentar að mörgu leyti vel en hefur þann ókost að tærast sé hún ekki varin. Þetta á einkum við þar sem raki, selta eða önnur efnaáraun er mikil. Við slíkar aðstæður geta önnur efni verið heppilegri sem bending …
