Book Seismic Assessment and Retrofit of Reinforced Concrete Columns

Download or read book Seismic Assessment and Retrofit of Reinforced Concrete Columns written by Konstantinos G. Megalooikonomou and published by Cambridge Scholars Publishing. This book was released on 2019-02-27 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reinforced concrete columns play a very important role in structural performance. As such, it is essential to apply a suitable analytical tool to estimate their structural behaviour considering all failure mechanisms such as axial, shear, and flexural failures. This book highlights the development of a fiber beam-column element accounting for shear effects and the effect of tension stiffening through reinforcement-to-concrete bond, along with the employment of suitable constitutive material laws.

Book Seismic Performance of Composite Beam columns

Download or read book Seismic Performance of Composite Beam columns written by Shannon D. Paboojian and published by . This book was released on 1993 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "An experimental study was undertaken to investigate the cyclic strength and ductility of composite columns subjected to simulatedseismic loading conditions. Eight two-thirds scale specimens were tested, each consisting of a structural steel shape encased in reinforcedconcrete. Parameters studied in the test program included: the degree of concrete confinement required to achieve adequate ductility; the effectiveness of shear studs for developing flexural stiffness and capacity under combined loading; the distribution of transverse shear resistance among the elements of the composite column; and concrete compressive strength. The results of the test program indicate that composite columns possess exceptional ductility and strength under cyclic loading if the buckling of longitudinal reinforcement is inhibited. Furthermore, the steel shape provides the primary resistance to transverse shear during overloading, and shear studs are not effective in enhancing the resistance against lateral loading. The elastic secant stiffness of the composite section corresponding to initial yielding of the longitudinal reinforcement was found to be well approximated by using one-half the gross moment of inertia (0.5I[subscript g]) in conjunction with Young's modulus for concrete. A prediction method based on superimposing the individual strengths of the reinforced concrete and structural steel shape was found to provide good agreement with test results. Current AISC LRFD provisions were determined to grossly underestimate the flexural capacity of the test specimens, which were axially loaded to 20% of their nominal pure axial load capacity [sic]."

Book Modelling and Analysis of Reinforced Concrete Structures for Dynamic Loading

Download or read book Modelling and Analysis of Reinforced Concrete Structures for Dynamic Loading written by Christian Meyer and published by Springer. This book was released on 2014-05-04 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive review of the material behavior of concrete under dynamic loads, especially impact and impuls, opens the volume. It is followed by a summary of the various analytical tools available to engineers interested in analyzing the nonlinear behavior of reinforced concrete members for dynamic load. These range from relatively simple and practice-oriented push-over analysis to sophisticated layered finite element models. Important design-related topics are discussed, with special emphasis on performance of concrete frames subjected to seismic loads. The significance of modern software systems is recognized by including extensive examples. For readers not current in dynamic analysis methods, an appendix contains a review of the mathematical methods most commonly used for such analysis.

Book Seismic Assessment and Retrofit of Reinforced Concrete Buildings

Download or read book Seismic Assessment and Retrofit of Reinforced Concrete Buildings written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2003-08-01 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most parts of the developed world, the building stock and the civil infrastructure are ageing and in constant need of maintenance, repair and upgrading. Moreover, in the light of our current knowledge and of modern codes, the majority of buildings stock and other types of structures in many parts of the world are substandard and deficient. This is especially so in earthquake-prone regions, as, even there, seismic design of structures is relatively recent. In those regions the major part of the seismic threat to human life and property comes from old buildings. Due to the infrastructure's increasing decay, frequently combined with the need for structural upgrading to meet more stringent design requirements (especially against seismic loads), structural retrofitting is becoming more and more important and receives today considerable emphasis throughout the world. In response to this need, a major part of the fib Model Code 2005, currently under development, is being devoted to structural conservation and maintenance. More importantly, in recognition of the importance of the seismic threat arising from existing substandard buildings, the first standards for structural upgrading to be promoted by the international engineering community and by regulatory authorities alike are for seismic rehabilitation of buildings. This is the case, for example, of Part 3: Strengthening and Repair of Buildings of Eurocode 8 (i. e. of the draft European Standard for earthquake-resistant design), and which is the only one among the current (2003) set of 58 Eurocodes attempting to address the problem of structural upgrading. It is also the case of the recent (2001) ASCE draft standard on Seismic evaluation of existing buildings and of the 1996 Law for promotion of seismic strengthening of existing reinforced concrete structures in Japan. As noted in Chapter 1 of this Bulletin, fib - as CEB and FIP did before - has placed considerable emphasis on assessment and rehabilitation of existing structures. The present Bulletin is a culmination of this effort in the special but very important field of seismic assessment and rehabilitation. It has been elaborated over a period of 4 years by Task Group 7.1 Assessment and retrofit of existing structures of fib Commission 7 Seismic design, a truly international team of experts, representing the expertise and experience of all the important seismic regions of the world. In the course of its work the team had six plenary two-day meetings: in January 1999 in Pavia, Italy; in August 1999 in Raleigh, North Carolina; in February 2000 in Queenstown, New Zealand; in July 2000 in Patras, Greece; in March 2001 in Lausanne, Switzerland; and in August 2001 in Seattle, Washington. In October 2002 the final draft of the Bulletin was presented to public during the 1st fib Congress in Osaka. It was also there that it was approved by fib Commission 7 Seismic Design. The contents is structured into main chapters as follows: 1 Introduction - 2 Performance objectives and system considerations - 3 Review of seismic assessment procedures - 4 Strength and deformation capacity of non-seismically detailed components - 5 Seismic retrofitting techniques - 6 Probabilistic concepts and methods - 7 Case studies
