What is the International Association of Fracture Mechanics for Concrete and Concrete Structures (IA-FraMCoS)

There are many conferences discussing damage, cracking and fracture of concrete, but mostly outside the context of fracture mechanics. There are many others dealing with fracture mechanics, but rarely with its application to concrete. To fill this gap was he motivation for founding FraMCoS.

Concrete is an archetypical quasibrittle material. It consists of brittle constituents and is characterized by a non-negligible material characteristic length which endows the material with a behavior that is transitional between the stress-strain relations for distributed damage at small scales and linear elastic fracture mechanics at large scales. This transitional behavior poses difficult challenges for theoretical, experimental and computational research.

Originally, IA-FraMCoS only activity was the triennial conference series with focus on concrete. Presently, it seeks to expand its activities to cover not only fundamental developments in concrete but also promotion of fracture-based approaches in engineering practice. Such an approach is long overdue in infrastructure life-cycle assessment (durability), environmental protection (long term waste storage, carbon dioxide sequestration), energy (nuclear vessels, fracking) and engineered design of new materials.

This will be accomplished not only through the perennial conferences, but also through seminar series, short courses (primarily to industry), and endorsements of high quality scientific research.

Professor Bićanić Passed Away

Prof. Bićanić passed away on Saturday October 8. Nenad Bicanic was a fine scientist and a dear friend with whom many of us interacted and enjoyed his warm friendliness. The FraMCoS community expresses its deepest condolences to his family.


Access to Two major projects data bases

Courtesy of Prof. Mazars, you are given access to two major data bases related to unique large scale testing programs in France. Framocs friends are encourage to further enrich this database for the benefit of all.


Framcos-9 Financial Statement

Framcos 9999 has reimbursed its loan from IA-Framcos, and has remitted to our "mother associaiton" an additional check of $18,659. Regretfully, our account was compromised and a fraudulent charge of $2,535 was incurred. Full financial statement can be found here.


New FraMCoS Fellows

Prof. John Bolander, Eric Landis, and Chandra Kishen were voted FraMCoS fellows.

Prof. Bolander and Landis were recognized for their excellent organization of FraMCoS-9 and Prof. Kishen for his extensive participation in many FraMCoS conferences along with a large contingent of students.


New Boad Members

New board members were voted during FraMCoS-9 conference: Profs. GianLuca Cusatis, Marco Di Prisco, Eric Landis, and Erik Schlangen.


Saouma Steps down

Though he should have served another three years as Past-President, Prof. Saouma has decided to step down from the Board in order to: a) better focus on other research activities; and b) make room for a younger generation of researcher to shape the association.


New ByLaws Approved

New set of Bylaws were voted by the General Assembly in Berkeley.



Succesfully held in Berkeley: 314 abstracts submitted, 205 conference presentations, 178 papers published, conference web site


Past FraMCoS president, resigns.

Past FraMCoS president, Jan van Mier "resigns".


Board Member Candidates

A sollicitation for Boad Members candidates was issued on 2016-03-30.

The BoD received 9 nominations, and in accordance with the Association ByLaws, six were retained, and Association members will soon be asked to vote electronically.

A total of four will be selected to serve with President Elect Gilles Pijaudier-Cabot.

Results will be announced at the General Assembly.


Proposed New Bylaws

Our Bylaws were first written in 1995, and subsequently evised in 2010.

With the accumulated expereince since then, it became obvious that they would have to be revised. After many (and at time spirited :- ) exchanges among the Board of Director and some members of the Board of Advisors, this 2016-Bylaws was voted by the BoD.

At the end of the document, a table summarizes the reason for each of the major modification.

Per our current (2010) Bylaws, The By-Laws of the Association and any amendments shall be agreed by not less than two-thirds of the number of members present at a General Meeting.

Hence, ths document is made available to our community for examination prior to the vote.

It should be noted that Board members are elected by the association members (whether preseent at the conference or not), whereas Bylaws amendmanets are to be voted by those present at the General Assembly.


Saouma Steps Down

Per the current (and proposed new) Bylaws, the current President serves another term as Past President.

Victor Saouma (current President) has decided to step down after the 2016 framcos and thus facilitating the selection of one additional board member who could hopefully revitalize our organization with "fresh blood" (and enable him to pursue other adventures.)


Conference Preparation

Framcos-9 preparations is going well. Indications are that we will have about 150-180 participants. Many (but not all ) have registered and paid. Reviews of final papers is nearly complete, and all authors should hear from us very soon. Any question: please contact secretariat at framcos9.org

High-Performance Fibre-Reinforced Cement-Based Composites (HPFRCC) For Future Infrastructure

This FraMCoS sponsored event will take place 26-31 July 2015, Dresden, Germany.


New Bylaws

A number of idiosyncrasies in the association Bylaws arose during the Toledo meeting, and there was different readings about certain important issues. As such, the President Elect (now President) of FraMCoS (V. Saouma) proposed to rewrite our ByLaws first written in 1995, and then slightly amended in 2010 to better address some propblems which arose in their interpretation and application.

Saouma submitted draft of the Bylaws (98 lines) to the Boards of Directors and Advisors on Oct. 14. Discussion was supposed to take place by Dec. 1 at which time they will be voted upon.

After much (email based) discussion (full report available upon request), the Board of Directors has voted the new Bylaws. In accordance with the current ByLaws, these should be voted by the Members/General Assembly.




First announcement, pen your calendar, framcos9 will be held in Berkeley May 29 June 1, 2016.


President Elect

Prof. Giles Pijaudier-Cabot has been voted by framcos members President Elect, will assume the presidency of our association in 2016, and will organize framcos-10 in Framce in 2019.


President Elect Election

On Oct. 15, invitation was sent to all 260 members to vote for the President Elect. Regretfully, the file was corrupted and the hyperlinks to the two candidates pointed to the same pdf file (pertaining to one of them). Fortunately, the error was immediately detected, and electronic vote cancelled. My apologies for this unfortunate mishaps.

A ballot will be sent again on Oct. 16 without hyperlinks. All members have already been notified by e-mail that the two candidates are:

For the record:

  • Voting is through the software Qualtrics
  • For maximum transparency, access to the web site has been given to all Board of Directors members. Qualtrics prevents anyone from altering vote.
  • Each framcos member will receive an individualized e-mail which will enable her/him to cast one single vote.
  • The same ballot would allow you to send comments to the Board of Directors.
  • Names are not recorded, however IP addresses are. Hence, you are strongly recommended to check the IP address of the computer through which you cast you vote should there be a future audit.
  • You should vote by Friday Nov. 1 2013 midnight (PDT).
  • Results will be immediately announced subsequently.
