Polypropylene Fiber Reinforced Concrete is an embryonic construction material which can be described as a concrete having high mechanical strength, Stiffness and durability. By utilization of Polypropylene fibers in concrete not only optimum utilization of materials is achieved but also the cost reduction is achieved. This paper presents a comprehensive review on various aspects Polypropylene F...

Corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (RC) structures deterioration in chloride-contaminated environments. As a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. The corrosion propagation phase is a ...

In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...

Fault, crushed zone, and other unfavorable geology may frequently appear in the construction of tunnels, so it is course necessary to study on dynamic properties tunnels crossing rock fracture zone. Taking tunnel faults as object, this paper discussed constitutive relation satisfied by structures researched loading features failure characteristics different faults. It shows that: (1) areas with...

ABSTRUCT: Recently, in the attention in response to global warming issues and sustainable society, the manufacturing using natural materials has become actively. Bamboo, low cost, fast growing, and broad distribution of growth, is expected to contribute significantly to earthquake-resistant construction and seismic retrofit technology in the developing countries. The authors also have been stud...

the use of polymer composite (frp) as a reinforcement material for the repair and strengthening of important components of reinforced concrete structures, particularly columns, has found wide spread. in this study, the effect of intermediate layer on improving the confinement behavior of reinforced concrete columns has been investigated. to achieve the objectives of the study, 14 cylindrical re...

This paper describes a method to analyze DC electric field generated by an railway considering influence of constructions. The finite element is effective solve problem including the constructions arbitrary shape, however analysis becomes time-consuming if includes steel material having fine structure such as reinforced concrete. authors introduced modeling methods concrete structures pole and ...
