Anil K. Chopra - Dynamics of Structures, Theory and Applications to Earthquake Engineering
Fifth Edition in SI Units
Pearson, 2020
pdf, 994 pages, english
ISBN-10: 1-29-224918-8
ISBN-13: 978-1-29-224918-6
An expert on structural dynamics and earthquake engineering, Anil K. Chopra fills an important niche, explaining the material in a manner suitable for both students and professional engineers with his fifth edition, in SI units of Dynamics of Structures: Theory and Applications to Earthquake Engineering. No prior knowledge of structural dynamics is assumed, and the presentation is detailed and integrated enough to make the text suitable for self-study.
As a textbook on vibrations and structural dynamics, this book has no competition. The material includes many topics in the theory of structural dynamics, along with applications of this theory to earthquake analysis, response, design, and evaluation of structures, with an emphasis on presenting this often difficult subject in as simple a manner as possible through numerous worked-out illustrative examples. The fifth edition, in SI Edition includes new sections, figures, and examples, along with relevant updates and revisions.
New to this Edition. Updates, Improvements, and Expanded Sections in the fifth edition, in SI units.
- Two new sections have been added to Chapter 20, which is now more than twice its previous size. These additions were motivated by the increasing use of nonlinear response history analyses (RHAs) of buildings in professional practice.
- Individual chapter updates and revisions include:
--- Chapter 13 has been extended to include a response-spectrum-based method to estimate principal stresses in continuum structures, such as concrete dams.
--- Chapters 7, 9, and 18 have been expanded to include P—analysis of gravity load effects and an introduction to their influence on the lateral response, permanent deformation, and collapse of structures.
--- Chapter 11 has been revised to include recent data on damping ratios determined by system-identification analysis of motions of 203 buildings recorded during earthquakes. New recommendations for estimating damping ratios to be used in earthquake analysis of structures are presented.
--- Chapters 22 and 23 have been updated to reflect the current editions of building codes for designing new buildings, and of performance-based guidelines and standards for evaluating existing buildings.
- Many new figures, several worked-out examples, and end-of-chapter problems have been added. |

Rarlab WinRAR v5.90 bra+chi+eng+ger+rus+spa+tur x32+x64
Архиватор RAR является самой распространенной программой после операционной системы и браузера, ведь большинство программ и в Интернете, и у пользователей хранятся в сжатом виде в архивах.
WinRAR – мощная утилита для создания и управления архивами, содержащая целый спектр дополнительных полезных функций. Программа WinRAR ежедневно используется миллионами людей во всем мире для экономии места на ПК и быстрой передачи файлов.
WinRAR больше не поддерживает Windows 98, Windows Me, Windows NT.
What's new in the latest version:
Version 5.90
1. RAR compression speed is improved for CPUs with 16 and more cores.
2. "Fastest" method (-m1 command line equivalent) typically achieves
a higher compression ratio for highly compressible data types
when creating RAR5 archives.
3. Maximum number of utilized threads is increased from 32 to 64.
Command line -mt<threads> switch accepts values from 1 to 64.
4. "Multithreading" parameter on "General" page of WinRAR settings
is replaced with "Threads" input field, where you can specify
the desired number of CPU threads. It can take values from 1 to
maximum number of available logical CPU units.
5. WinRAR displays packed and unpacked folder sizes when browsing
archive contents.
6. "Total folders" field is added to list of archive parameters
displayed by WinRAR "Info" command. Same field is added to
"Archive" page in archive properties in Windows Explorer.
7. Window including a progress bar and "Cancel" button is displayed
if reading archive contents takes noticeable time.
It can be useful for archive formats with slower access to contents,
such as large TAR based archives like .tar.gz and tar.bz2.
8. Archiving and extraction progress windows, also as progress windows
for some other commands, can be resized.
9. "Repair" performance for RAR5 archives with recovery record
and without data shifts is improved. It deteriorated in WinRAR 5.80
and is now restored to original level.
10. Password prompt is not issued when performing recovery record based
repair for RAR5 archives with encrypted file names.
This command can be performed without providing a password.
11. If folder for converted archives in "Convert archives" command
does not exist, WinRAR attempts to create it. Previous versions
failed to create converted archives in non-existent destination folder.
12. Added extraction support for GZIP archives with optional header
checksum field.
13. Bugs fixed:
a) "Repair" command could erroneously display "Recovery record is
corrupt" message when processing an archive with valid recovery
record. This message did not prevent further repair operation;
b) if quick open information option was set to "Do not add" in default
compression profile and this profile was loaded by some command
or dialog, WinRAR ignored quick open information when browsing
contents of RAR archives. For example, it happened after opening
archiving or password dialogs;
c) Ctrl+C "Copy" shortcut key did not work in archive comment window;
d) if "Put each file to separate archive" and "Archives in subfolders"
options were set, WinRAR ignored the destination path specified
in archive name field. |
