This book was released on 2017-12-03 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of concrete is limited because it has low tensile strength. For this reason, it is reinforced and one of the most popular reinforcement is steel. Steel reinforcement at some point may no longer be available or feasible. In current energy crisis scenario, there exists a need for more economical and readily available substitute reinforcement for concrete. Since production of steel rebar requires huge amount of energy, so the main focus of this research work lies in investigating the use of bamboo as potential reinforcement in concrete beams. Through this book we get the idea whether the strips of bamboo have a potential substitute to steel bars in concrete or not. For carrying out the experiments, different types of tests on bamboo material have conducted to find various properties of the material to be used in the design of bamboo reinforced beams. These properties included water absorption, tensile strength, compressive strength and bond strength. After obtaining all mentioned parameters, the bamboo reinforced concrete beams were designed with same reinforcement ratio but different types of patterns of the bamboo reinforcement strips. A beam for same loading parameters was also designed with steel rebar as its main reinforcement. All these beams after casting were tested to compare their first crack loads, ultimate loads and failure patterns as well as working out whether the bamboo material was displaying comparable resistance to the loads like steel rebar beams. Their load deflection graphs and comparison charts were plotted and all their properties compared and quoted in-terms of their loading failure types, amount of strength improvement among bamboo reinforced beams, their bond stress comparisons and ultimately declaring their suitability or unsuitability as a rebar element in concrete beams.

Available in PDF, EPUB and Kindle. Book excerpt: This study presents the evaluation of the feasibility of the use of bamboo as a potential reinforcement in concrete structural members. To achieve this objective a series of tensile tests on three types of bamboo Solid; Moso; and Tonkin; were conducted to obtain their constitutive relation. Also, four-point bending tests on concrete beams reinforced with bamboo were performed to identify their behavior compared to steel reinforced concrete members. Tensile tests specimens were prepared by cutting the bamboo typically in 1/2 in (13 mm) wide strips of 9 to 12 in (228 mm to 305 mm) in length. In order to prevent crushing of the bamboo samples when placed in grips of the MTS machines end-tabs were epoxy glued to the bamboo samples. The results for the tensile tests which we performed indicated that the presence of nodes in Solid Bamboo samples did not affect the behavior. Six four-point bending tests were conducted on 8 in x 20 in x 96 in (203 mm x 508 mm x 2429 mm) reinforced bamboo concrete beams. The initiation and widening of cracks and their respective loads were recorded. The test results were compared with plain concrete and steel reinforced concrete beams behavior. In general, the test results indicated that bamboo reinforcement enhanced the load carrying capacity by approximately 250% as compared to the initial crack load in the concrete beam.

Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, concrete is highly contributed in the construction works for its various advantages such as low cost, availability, fire resistance and others. Generally, concrete is high in compressive strength but relatively low in tensile strength. Steel is the mostly used for the reinforcement of concrete due to its high tensile strength. Alternate materials such as fibres are used to increase the tensile strength of the concrete. Bamboo is natural, cheap and readily available material. Most importantly, bamboo has a high tensile strength. This research is aimed at studying the performance of concrete with bamboo fibres as additives in it. The objective of this research was to experiment the structural behaviour of bamboo fibres reinforced concrete (BFRC) with various length of bamboo fibres as additives. In this paper, 2% of bamboo fibres by volume of the concrete with the length of 40mm and 60mm are added into concrete and compare with the plain concrete which act as the control specimen. 2 tests are tested which are the cube compression test and flexural test. From the test result has shown that the compressive strength of different length of BFRC is lower as compared to the controlled cube specimen. For flexural strength, the 40mm BFRC is the most optimum length as it has shown the almost similar strength with the controlled beam specimen. The flexural strength for the 60mm BFRC is slightly lower than that of the controlled beam specimen.

Available in PDF, EPUB and Kindle. Book excerpt: In this book I have collected many reports on the properties of bamboo. Since I started bamboo research in 1974, I have collected many publications on bamboo. However, in contacts with other researchers I became aware of the fact that several of these publications were unknown to them. Consequently their activities in research or in bamboo projects had to start at a lower level than if they had known some of these publications. Therefore, I discussed the need for a book like this with several colleagues, and I decided to start writing. In this book I present data on properties, as published by resear chers. Certainly it is not complete; e.g. the proceedings of the bamboo workshop in Cochin in November 1988 are not included; they arrived just too late to be taken into account. On the other hand, in writing this preface I realize I have forgotten my own thesis. I do apologize to any colleague whose relevant report is not taken into account as well. I like to express my feelings of respect to the board of my faculty: they allowed me to spend so much time on this book, and they gave a considerable financial support for the printing costs.

Download or read book Strengthening of Reinforced Concrete Structures written by L C Hollaway and published by Elsevier. This book was released on 1999-03-05 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The in situ rehabilitation or upgrading of reinforced concrete members using bonded steel plates is an effective, convenient and economic method of improving structural performance. However, disadvantages inherent in the use of steel have stimulated research into the possibility of using fibre reinforced polymer (FRP) materials in its place, providing a non-corrosive, more versatile strengthening system. This book presents a detailed study of the flexural strengthening of reinforced and prestressed concrete members using fibre reinforces polymer composite plates. It is based to a large extent on material developed or provided by the consortium which studied the technology of plate bonding to upgrade structural units using carbon fibre / polymer composite materials. The research and trial tests were undertaken as part of the ROBUST project, one of several ventures in the UK Government's DTI-LINK Structural Composites Programme. The book has been designed for practising structural and civil engineers seeking to understand the principles and design technology of plate bonding, and for final year undergraduate and postgraduate engineers studying the principles of highway and bridge engineering and structural engineering.

Download or read book Engineered Bamboo Structures written by Yan Xiao and published by CRC Press. This book was released on 2022-04-29 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bamboo is in the spotlight as a potential building material in the current pursuit of a CO2-neutral society, due to its rapid maturation and excellent mechanical properties. Despite the growing interest in bamboo in academia and society, there is a lack of systematic understanding of the fabrication, design and construction processes using bamboo as a modern industrial material. This is the first book to describe a new category of structural systems constructed with engineered bamboo. It gives a definition of engineered bamboo (glubam) in an analogy with steel structures and wood structures. Structural systems and components have been designed using glubam; then industrialized production processes of glubam are described. Based on state-of-the-art research, design guidelines are suggested, in a comparable and parallel approach to the existing guidelines for composite wood structures. The book also discusses bamboo structures in the context of sustainable development, including the benefits of using bamboo as an alternative or replacement for wood, especially for developing countries, many of which are faced with the lack or destruction of forest resources.
