Abstract:

An analytical and experimental investigation on the shear strength of High Performance Concrete (HPC) beams with vertical shear reinforcement or stirrups was carried out. The analytical work involved developing a theory based on the truss analogy, capable of predicting the response and shear strength of such beams subjected to combined bending moment and shear force.The experimental work comprised forty-eight beam specimens in eight series of tests. Most of the beams were 250 mm wide, 350 mm deep and had a clear span of approximately 2 metres. The largest beam was 250 mm wide, 600 mm deep and

Abstract:

Continuous beams represent main structural elements in most reinforced concrete (RC) structures such as parking garages and overpass bridges. Deterioration of such structures due to corrosion of steel reinforcement is common in North America. To overcome the corrosion problems, the use of fiber-reinforced polymer (FRP) bars and stirrups becomes a viable alternative to steel reinforcement. However, to date, the shear behaviour of FRP-RC continuous beams has not been explored yet. As such, the objective of this study is to investigate the shear behaviour of such beams.

Abstract:

Ultra-High Performance Concrete (UHPC) is a new class of concrete characterized by no coarse aggregate, steel fiber reinforcement, low w/c, low permeability, compressive strength exceeding 29,000 psi (200 MPa), tensile strength ranging from 1,200 to 2,500 psi (8 to 17 MPa), and very high toughness. These properties make prestressed precast UHPC bridge girders a very attractive replacement material for steel bridge girders, particularly when site demands require a comparable beam depth to steel and a 100+ year life span is desired.

Ultra-high performance concrete (UHPC) is a new type of concrete developed by selecting the particle sizes and gradation in the nano- and micro-scales targeting the highest possible packing. The resulting concrete with very high density is called UHPC. UHPC has very low permeability and hence it is very highly durable compared to traditional or high performance concrete (HPC). Micro reinforcement of UHPC by random distributed steel-synthetic fibers results in superior mechanical properties such as very high compressive and tensile strengths, high ductility, and high fatigue resistance.

Abstract : Deep reinforced concrete beams are commonly used as transfer girders or bridge bents, at which its safety is often crucial for the stability of the whole structure. Such elements are exposed to the aggressive environment in northern climates causing steel-corrosion problems due to the excessive use of de-icing salts. Fiber-reinforced polymers (FRP) emerged as non-corroded reinforcing materials to overcome such problems in RC elements.

博士<br>國立成功大學<br>土木工程學系碩博士班<br>91<br>The torsion design provisions based on the thin-walled tube analogy for reinforced concrete members had been adopted in the ACI 318-95 Code, in which, the solid and hollow sections were idealized as a thin-walled tube, and the torsional capacity of a section was directly related to the effective wall thickness . This paper investigated the torsional strength and behavior of high and normal-strength concrete beams under pure torsion. An analytical model was developed which combines the basic concepts of skew-bending theory and thin-walled tube analogy for pr

碩士<br>國立中興大學<br>土木工程學系<br>86<br>The purpose of the study is to investigate the shear behavior of high performance concrete (HPC) beam and the low cement high performance concrete (LcHPC) beam with a cement content of 250 kg/cm3. Fourteen full scale specimens without stirrups were made for testing. The considered parameters include the shear-span to effective depth ratio (a/d), the percentage of longitudinal steel content (ρ) and the different amount of cement. The results show that the she

It is advantage is the increase of the building is resistance against horizontal shear force. To describe more specifically, ductile coupled shear wall increase the toughness of the whole building on the horizontal axis, and the main damage of earthquakes are on the horizontal axis. Because of the need of underground parking lot, holes are needed to be drilled through ductile coup
