Six full-scale prestressed concrete (PC) I-beams with steel fibers were tested to failure in this work. Beams were cast without any traditional transverse steel reinforcement. The main objective of the study was to determine the effects of two variables—the shear-span-to-depth ratio and steel fiber dosage, on the web-shear and flexural-shear modes of beam failure. The beams were subjected to
For prestressed concrete construction, the current standard for buildings is BS8110 and for bridges BS5400, which suggest an initial prestressing force of 70% of the characteristic failing load. For ties and similar appliions in structural steel construction, the requirements of BS5950: Parts 1 and 2 apply.
lengths of 12.7mm diameter CFRP bars prestressed to 30%, 45% and 60% was found to be 25d b, 40d b, 54d b, respectively. Measured transfer lengths of the 12.7mm diameter CFRP bar prestressed to 30% in SCC met the ACI440.4 prediction. However, as the

Standard Specifiions for Concrete Structures (JSCE-SSCS), which show the model for plan, design, execution, maintenance and repair of concrete structures, have been highly recognized in practice and contributed to the development of concrete technology in Japan since its first publiion as “Standard
Today, the steel reinforcements in concrete structures are mostly prestressed hydraulically. This requires ducts for guiding the tension cables, anchors for force transfer and oil-filled hydraulic
10. Fatigue strength is better due to small variations in prestressing steel, recommended to dynamically loaded structures. Disadvantages of Prestressed Concrete 1. The availability of experienced builders is scanty. 2. Initial equipment cost is very high. 3.

1/1/1971· Concrete roof systems have three basic advantages over competitive materials- esthetic appeal, structural economy and functional utility. Double-tees are the most widely used prestressed concrete product in the minimum-span range. Double-tees may be used for
The subject of the present invention, therefore, is a novel type of prestressed reinforced concrete and composite construction. Prestressed reinforced concrete had previously been proposed and some use thereof has been made in structures. However, it has

This paper developed an analytical software, called Simulation of Concrete Structures (SCS), which is used for numerical analysis of shear-critical prestressed steel fiber concrete structures. Based on the previous research at the University of Houston (UH), SCS has been derived from an object-oriented software framework called Open System for Earthquake Engineering Simulation (OpenSees
