Available in PDF, EPUB and Kindle. Book excerpt: A new finite element model for reinforced concrete beam-column joints is proposed. The model considers the effects of bond-slip and shear deformations in the joint panel region. The problems associated with modeling bond-slip of anchored reinforcing bars are discussed. The proposed bond-slip model is examined at the element level by comparing its predictions with other analytical and experimental results. The ability of the model to simulate bond deterioration and eventual pullout of anchored reinforcing bars under severe cyclic excitation is demonstrated. This model is incorporated into the global beam-column joint element. Further comparisons are made between the predictions of the proposed beam-column joint model and other analytical and experimental results under reversed cyclic loading to show the validity of the model to describe the bond-slip behavior of the joints.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For reinforced concrete (RC) structures subjected to seismic loads, buckling of longitudinal reinforcing bar is a significant damage stage. The objective of this research is to identify the critical parameters that control the buckling of reinforcing bars in typical circular and rectangular RC columns subjected to cyclic lateral loads. A series of nonlinear finite element simulations of laterally loaded RC columns are carried out to simulate reinforcing bar buckling behavior. Next, to achieve computational efficiency and enable a large range of simulations for a parametric study, a simplified "bar-with-springs" model is developed wherein the longitudinal reinforcing bar in a column is isolated and simulated as a flexural member. The combined restraining mechanism affected by transverse reinforcing and column size is represented by springs at the location of each transverse bar. The simplified model is validated through comparison of average stress-strain curves of "bar-with-springs" models with corresponding "full column" models. After the validation of proposed models, which are capable of providing with "average stress-strain" response of longitudinal bars, an equivalent material model is developed for reinforcing steel in RC columns that implicitly incorporates the degrading effects of bar buckling. A comprehensive parametric study is performed to identify the effects of several important column parameters on the buckling behavior of the longitudinal reinforcement in RC columns. Features of average stress-strain curves of compressively loaded reinforcing bars are summarized. Constitutive relations as functions of critical column parameters are developed for the direct use in nonlinear structural analysis of RC structures. Comparison of the numerically simulated global response of experimentally tested RC columns confirm the value and significance of the proposed equivalent material models as a simple and effective way to include bar buckling effects in finite element analysis of RC structures.

Book excerpt: Proceedings of the U.S.?Japan Seminar on Post-Peak Behavior of Reinforced Concrete Structures Subjected to Seismic Loads: Recent Advances and Challenges on Analysis and Design, held in Tokyo and Lake Yamanaka, Japan, October 25-29, 1999. Sponsored by the National Science Foundation, U.S.A.; Japan Society for the Promotion of Science; Japan Concrete Institute. This collection presents the latest ideas and findings on the inelastic behavior of reinforced concrete (RC) structures from the analysis and design standpoints. These papers discuss state-of-the-art concrete material models and analysis methods that can be used to simulate and understand the inelastic behavior of RC structures, as well as design issues that can improve the seismic performance of these structures. Topics include modeling of concrete behavior; modeling of RC structures (finite element approach and macro-element approach); and experimental studies, analysis, and design issues.

Download or read book Testing of Anchors and Reinforcing Bars in Concrete Under Cyclic Crack Movements written by C. Mahrenholtz and published by . This book was released on 2016 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests on anchors and reinforcing bars in cracked concrete members with cyclically opening and closing cracks are carried out to study their performance under variable live loads and seismic loads. Cyclic crack tests are the most demanding and often decisive test series conducted for the qualification of anchors, which were cast-in or post-installed in concrete. Research in the field of seismic engineering also requires cyclic crack tests on anchors as well as on reinforcing bars. Testing of anchors and reinforcing bars in cyclic cracks makes special considerations with respect to the test specimen, test setup, and test procedure necessary. This article provides guidance, discusses how to carry out the technically challenging cyclic crack tests, and presents an example.

This book was released on 1997 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Jan. 17, 1995, Hyogoken-Nanbu Earthquake was one of the worst disasters to hit Japan in almost half a century. It has been compared in its impact to the great Kanto (Tokyo) Earthquake of 1923. The Kobe-Osaka region held many similarities in its geologic and tectonic setting to many areas along the West Coast, and possibly, other areas of the U.S. A geotechnical reconnaissance to identify the relevant problems and issues was organized. This report provides a timely, first-hand overview of the type and extent of the geotechnical aspects of the damage.

Download or read book Connections between Steel and Concrete written by Rolf Eligehausen and published by ibidem-Verlag / ibidem Press. This book was released on 2012-02-27 with total page 1430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anchorage by fasteners and composite structures of steel and concrete have seen dramatic progress in research, technology and application over the past decades. The understanding of the fundamental principles underlying both disciplines has significantly improved. Concurrently, there has been rapid growth in the development of sophisticated new products and the establishment of international directives and codes to ensure their safe and economical use in a wide range of engineered structures. Although they deal with very similar problems, the two disciplines have developed independently from each other. To optimize the use of composite structures and fastenings to concrete, however, it is necessary to have knowledge of both: the local behavior of the fastening system and the global behavior of the structure. It became apparent that a forum offering the opportunity to expand and to exchange experience in the field of connecting steel and concrete would benefit all involved. Furthermore this forum would aid in the rapid dissemination of new ideas, technologies and solutions as well as explore new areas of research.This book forms the Proceedings of the 2 Symposium on “Connections between Steel and Concrete”. As the 1 Symposium in 2001 it brought together leading experts from all facets of the research, design, construction and anchor manufacturing community from around the world. Their lectures covered the topics:- test methods- behavior and design- dynamic loading: shock, earthquake, fatigue- durability- exceptional applications, strenghtening and structures- related topicsIn total 129 papers are gathered in these 2 volumes.
