Shear Strength of Prestressed Steel Fiber Concrete I …

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

POST TENSIONING SYSTEM - Macalloy - PDF alogs | …

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.

STANDARD SPECIFIIONS FOR CONCRETE STRUCTURES 2007 …

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

Memory steel—a new material for the strengthening of …

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

LECTURE NOTES ON

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.
