I would like to share the articles that explained the problem in using viscous damping in structural modelling, particularly in nonlinear time history analysis. It is included some solutions to avoid it, e.g. article of Zareian & Medina (2011).
These all are very useful articles and a must to have!!
Cheers.

[REQUEST] OFFICE BUILDINGS: STANDARD METHODS OF MEASUREMENT (ANSI/BOMA Z65.1 – 2010)
BOMA International > Standards > Office Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.1 – 2010)
BOMA SETS THE STANDARD IN MEASURING BUILDINGS
In 1915, BOMA International published the first Standard Method of Floor Measurement for Office Buildings. It has been accepted and approved by the American National Standards Institute. Throughout the years, the standard has been revised to reflect the changing needs of the real estate market and the evolution of office building design.
BOMA International is pleased to introduce the latest version of the office standard.This version signifies a major revision, including a new name Office Buildings: Standard Methods of Measurement (ANSI/BOMA Z65.1 – 2010). The objective of the office standard is to provide a uniform basis for measuring rentable area in both exiting and new office buildings by taking a building-wide approach to floor area measurement. It provides a methodology for measuring both occupant space as well as the space that benefits all occupants.
The objective of this study is to investigate the buckling behavior of cold formed steel lipped channel columns. Specific objective of study is to check effectiveness of current Indian standard prequalified section database.
Literature study exposes a lack of understanding of this subject. Computational modeling using finite strip method has been carried out along with experimental verification. The finite strip models were used to generate additional database required for parametric study on buckling behavior of cold-formed steel lipped channel sections. Results of parametric study were used to understand various buckling modes.
At the end of the study, some limits to geometric parameter are suggested in order to delay local and distortional buckling of cold-formed steel lipped channel in compression.

Monitoring in Coastal Environments Using Foraminifera and Thecamoebian Indicators
Author: David B. Scott, Franco S. Medioli, Charles T. Schafer | Size: 17.30 MB | Format:PDF | Publisher: Cambridge University Press | Year: 2001 | pages: 192 | ISBN: 0521561736
Review
"...the great strength of the book is that it demonstrates, to a wider audience, that microfossil data can provide environmental consultants and resource managers with cost-effective and, at the same time, crucial environmental background (long-term) information, which they cannot obtain by other means!" Geology Magazine
"The authors have contributed significantly to this body of literature... this book provides a valuable overview... this reference should help focus attention on the applicaton of Foraminifera and Thecamoebians to environmental problems and highlight potential lines of inquiry." Susan T. Goldstein, Quareterly Review of Biology
"This book is a useful overview of the application of foraminiferal and thecamoebian analysis to environmental monitoring in coastal environments. I have not come across a comparable book, so this really fills an unoccupied niche! The authors have successfully minimized the use of micropaleontological jargon while stressing the potential uses of these microfossils as environmental proxies...The book is richly illustrated..." Ecoscience
Product Description
Here is the first comprehensive book to describe specific environmental applications of foraminifera and thecamoebians. These organisms permit the biological characterization of a variety of freshwater and coastal marine environments and react quickly to environmental stress, natural or anthropogenic. Their small size and hard shells lead to preservation in large numbers in core samples, allowing their use as proxies to reconstruct past environmental conditions. The book introduces the topic to nonspecialists and then goes on to give detailed descriptions of the methods and techniques. Resource managers and consultants in the public and private sectors who routinely work on coastal environmental problems will find this book invaluable.

Book Description:
The ability to manipulate spatial data in different forms and to extract additional meaning from them is at the heart of GIS, yet genuine spatial analysis tools are rarely incorporated into commercial software, thus seriously limiting their usefulness. The future of GIS technology wil depend largely on the incorporation of more powerful analytical and modelling functions - and there is agreement within the GIS community of the urgent need to address these issues. This text attempts this task. It presents the latest information on incorporating spatial analysis tools into GIS, and includes concepts and applications from both the environmental and socio-econimc sciences.

Performance-Based Seismic Design is now widely recognized as the pre-eminent seismic design and assessment methodology for building structures. In recognition of this, seismic codes may require that buildings achieve multiple performance objectives such as withstanding moderate, yet frequently occurring earthquakes with minimal structural and non-structural damage, while withstanding severe, but rare earthquakes without collapse and loss of life. These objectives are presumed to be satisfied by some codes if the force-based design procedures are followed. This paper investigates the efficacy of the Eurocode 8 forcebased design provisions with respect to RC frame building design and expected seismic performance. Four, eight, and 16-storey moment frame buildings were designed and analyzed using the code modal response spectrum analysis provisions. Non-linear time-history analyses were subsequently performed to determine the simulated seismic response of the structures and to validate the Eurocode 8 force-based designs. The results indicate the design of flexural members in medium-to-long period structures is not significantly influenced by the choice of effective member stiffness; however, calculated interstorey drift demands are significantly affected. This finding was primarily attributed to the code’s enforcement of a minimum spectral ordinate on the design spectrum. Furthermore, design storey forces and interstorey drift demand estimates (and therefore damage), obtained by application of the code force-based design procedure varied substantially from those found through non-linear time-history analysis. Overall, the results suggest that though the Eurocode 8 may yield lifesafe designs, the seismic performance of frame buildings of the same type and ductility class can be highly non-uniform.
