INTRODUCTION
The properties of Specially Concentric Braced Frames (SCBF) systems have the potential to meet multiple performance objectives. However, previous research has shown that the current design procedures can lead to soft stories, inadequate gusset plate connections, unexpected failure modes, brittle welds and premature brace failure. To improve the performance and to meet the engineering needs of future seismic load resisting systems, an international research team is working to develop Tomorrows Concentric Braced Frame (TCBF) systems. This research team receives support from the NEES program and the National Science Foundation with a NEESR Small Group project entitled "International Hybrid Simulation of Tomorrows Braced Frame Systems". The international team of collaborators includes researchers from the University of Washington (UW), the University of California Berkeley (UCB), the University of Minnesota (UM) and the NCREE Laboratory in Taiwan. Researchers from Japan, Canada, industry professionals and practicing engineers are also collaborating on this project.
for more drawings,photos and seeing phase 2
please visit above link,
i think ,this post useful for forum memebrs
in additional,
if you visit the 3.link,you can view plot results.
like frame displacements etc..

Fracture Resistance Testing of Monolithic and Composite Brittle Materials
Fracture Resistance Testing of Monolithic and Composite Brittle Materials
(ASTM Special Technical Publication, 1409)
ASTM International; illustrated edition (January 1, 2002) | English | 0803128800 | 237 pages | PDF | 4.31 MB
STP 1409 features 14 peer-reviewed papers that summarize the latest methods for the measurement of fracture toughness, slow crack growth, and biaxial strength. It also identifies new areas for fracture toughness test methods development and standardization, such as testing of complex materials, elevated temperature measurement, and R-curve measurement.
5 sections cover:
· Plenary Session – discusses 30 years of progress in fracture mechanics of brittle materials.
· Implications For Design and Testing – focuses on the analysis of plates for biaxial strength testing and the transition in measured fracture toughness from a value associated with the properties of a single grain to the polycrystalline value.
· Fracture Toughness Standardization – examines 3 techniques that were developed and standardized as part of ASTM C 1421 Standard Test Methods for Determination of Fracture Toughness of Advanced Ceramics at Ambient Temperatures. These techniques show convergence when good metrology is employed. In addition to standardized techniques, this section discusses the single edged V-notched beam method that is on a fast track for standardization in Europe.
· Crack Growth Resistance – covers testing of functionally graded materials, elevated temperature R-curve testing, and the study of a toughening mechanism. Although most researchers applied classical mechanical techniques for the measurement of fracture toughness or crack growth resistance, both theoretical and fractographic methods were also presented.
· Unique Materials and Environmental Effects – examines elevated temperature fracture toughness testing of particulate reinforced ceramic composites, thermal and environmental effects on the fracture toughness of titanium carbonitrides for machining, and environmental interactions that lead to rate effects in "dynamic fatigue" (i.e., stress corrosion) testing.

Geosynthetics in Civil Engineering
Publisher: Woodhead | Pages: 312 | 2006-12-22 | ISBN 1855736071 | PDF | 6 MB
Building a strong foundation in the fundamentals of geosynthesis, Geosynthetics for Civil Engineering discusses the design and durability of geosynthetics together with their material properties and the international standards governing their use. The book examines the various applications of geosynthetics in areas such as filters, separators, landfills, barriers, and foundation materials. It covers design concepts, manufacturing, costs, the use of different natural and synthetic materials, methods of quality assurance, and the service life of geosynthetics. Written by an international team of contributors, the book is ideal for civil engineers and producers of geosynthetics.

behavior of long links in eccentrically braced frames
The Earthquake Engineering Online Archive
Behavior of long links in eccentrically braced frames
Engelhardt, Michael D.; Popov, Egor P.
UCB/EERC-89/01, Earthquake Engineering Research Center, University of California, Berkeley, 1989-01, 406 pages (510/E532/1989)
This report describes an experimental investigation and associated studies of the behavior of long, flexural yielding links in seismic-resistant eccentrically braced frames (EBFs). EBFs provide ductile behavior under severe earthquake loads by restricting yielding to beam segments called "links." The central focus of this report is an experimental investigation of 14 2/3-scale subassemblages subjected to cyclic loads. The subassemblages model a portion of a single-diagonal EBF with the links attached to the columns. Based on the findings of this investigation, combined with the results of previous EBF research, preliminary design recommendations are provided for the use of long links not attached to columns. Included are recommendations on the design yield strength, ultimate strength, plastic rotation capacity, and stiffening requirements for long links. The suitability of brace-to-link connection details for use in EBFs with long or short links is also demonstrated.
