Dynamics of Structures, Anil K. Chopra, 4th Edition (2012)

Anil K. Chopra, "Dynamics of Structures, 4th Edition"
2012 | ISBN-10: 0132858037, 0273774247 | 992 pages | PDF | 16,7 MB

Designed for senior-level and graduate courses in Dynamics of Structures and Earthquake Engineering. 
Dynamics of Structures includes many topics encompassing the theory of structural dynamics and the application of this theory regarding earthquake analysis, response, and design of structures. No prior knowledge of structural dynamics is assumed and the manner of presentation is sufficiently detailed and integrated, to make the book suitable for self-study by students and professional engineers.

Seismic Provisions for structural steel buildings. (2005)



 Seismic Provisions was written as a supplement to the current AISC Specification for Structural Steel Buildings(ANSI/AISC 360-10) and provides design requirements for high seismic force resisting systems. In addition to the usual technical updates and clarifications made in all editions of the Seismic Provisions, the effort for the 2010 edition also focused on an improved format and streamlined presentation. The organization of the chapters has been changed to be more consistent with that of ANSI/AISC 360. In the 2005 edition, the requirements for structural steel buildings were separated from those for composite structural steel/reinforced concrete construction, and were identified as Part I and Part II. In this edition of the Provisions, Part I and Part II have been combined into one cohesive and consistent document.

97-S89 Seismic Behavior of Short Coupling Beams with Different Reinforcement Layouts

Document Name:97-S89
Author(s):Luciano Galano and Andrea Vignoli
Publication:Structural Journal
Volume:97
Issue:6
Pages:876-885
Keywords:cyclic loads; ductility; earthquake-resistant structures; shear walls.
Date:November 1, 2000
Abstract:


An experimental investigation on the seismic behavior of reinforced concrete coupling beams is presented. The reinforcement layout and the loading history were the main variables of the tests. Fifteen short coupling beams with four different reinforcement arrangements were tested. They were subjected to monotonic and cyclic loading by a suitable experimental setup. All specimens were characterized by a shear span-depth ratio of 0.75. The reinforcement layouts consisted of: a classical scheme (a); diagonal scheme without confining ties (b1); diagonal scheme with confining ties (b2); and inclined bars to form a rhombic configuration (c). Concrete compressive strengths of the specimens varied from 40 to 54 MPa. Test results showed that the beams with diagonal or rhombic reinforcement layouts behaved better than beams with longitudinal arrangement of the steel bars. These results were produced by the different resisting truss mechanisms that were developed in the coupling beams after the first cracking. The differences in energy dissipation were negligible between the diagonal and rhombic layouts. The rhombic arrangement, however, was more advantageous in terms of rotational ductility capacity, and decay in strength and stiffness of the beams. Moreover, cyclic tests demonstrated that the behavior of the rhombic layout was less affected by the different loading histories

Seismic Stratigraphy, Basin Analysis and Reservoir Characterisation, Volume 37,( 2006)




Seismic Stratigraphy Basin Analysis and Reservoir Characterisation summarizes basic seismic interpretation techniques and demonstrates the benefits of intergrated reservoir studies for hydrocarbon exploration. Topics are presented from a practical point of view and supported by well-illustrated case histories. Modern geophysical techniques allow more accurate prediction of the subsurface geology. The dynamics of sedimentary environments are discussed with global controling factors, and a link is made to high-resolution sequence stratigraphy. 



* Discusses the link between seismic stratigraphic principles and sequence stratigraphy
* Provides techniques for seismic reservoir characterization, as well as well control

* Analyzes inversion, AVO and seismic attributes

Seismic behaviour of steel coupling beams linking reinforced concrete shear walls








ABSTRACT Due to lack of information, current design methods to calculate embedment length for steel coupling beams linking concrete shear walls are tacit about cases in which the beams have connection details to the walls that include stud bolts and horizontal ties. In this study, analyses were carried out to develop a model for calculating the embedment lengths of embedded steel sections. Five models for calculating embedment lengths in hybrid coupled walls are developed as variations of the Prestressed Concrete Institute guidelines for steel brackets attached to reinforced concrete columns. In addition, experimental studies on the steel coupling beam were carried out. The main test variables were the ratios of the coupling beam strength to the connection strength. Based on the test results, it is more advantageous to design the coupling beams as shear-yielding members since a shear-critical coupling beam exhibits a more desirable mode of energy dissipation than a flexure-critical coupling beam.
