About JCSS

The JCSS is a committee in the field of Structural related Risk and Reliability, acting on behalf of the Liaison Committee of the following six international professional associations:

CIB International Council for Research and Innovation in Building and Construction
ECCS European Convention for Constructional Steelwork
fib fib International Federation for Structural Concrete
IABSE IABSE International Association for Bridge and Structural Engineering
RILEM RILEM

Reunion internationale des Laboratoires et Experts des Materiaux

 

IASS International Association for Shell and Spatial structures

Terms of Reference

  • To provide general knowledge and decision support for the life-cycle based management of safety, reliability, risk, robustness, durability, resilience and sustainability for the built environment, on the basis of sound scientific principles and with an open eye for the applications in practice.
  • To take care that inter-associational pre-normative research in the field of Risk and Reliability is performed in an effective and adequate way.
  • To strive for coordination between the interassociational pre-normative research and normalization activities in ISO, Eurocode etc. 
  • To provide appropriate support and technical co-ordination for the work of the Member Associations.

History

In 1971 the Liaison Committee which co‐ordinates the activities of five international associations in civil engineering, composed of CEB, CIB, fib, IABSE and RILEM, created a Joint Committee on Structural Safety, JCSS, with the aim of improving the general knowledge in structural safety. The JCSS under the chairmanships of the late Prof. J. Ferry‐Borges, Portugal, followed by Prof. J.Schneider, Prof. R. Rackwitz, Prof. T. Vrouwenvelder, Prof. M.H. Faber, Prof. J.D. Sørensen and now Dr. Inger B. Kroon has had over 60 meetings. During these meetings more than 250 papers on structural safety and related matters have been discussed. Several documents of general character and interest have been prepared and published. These documents supplied the background for the preparation of guidance documents concerning the design and construction of different types of structures and materials, among others several ISO documents, Eurocodes and the CEB and ECCS Model Codes.

Organisation

The JCSS consists of a Board, chaired by the President, and a number of Working Parties, chaired by Reporters. The initiation of a new Working Party is proposed by the Board and needs endorsement by the Liaison Committee.

The Board

The Board consists of the President, the former President, the Reporter(s) and one Member-Specialist per Association. All members are designated for a 5-year period but they may be reappointed. The President of the JCSS issues invitations for and chairs the meeting of the Plenum, and secures the co-ordination within JCSS and between the JCSS and the Liaison Committee. The Board meets at intervals of one year. It discusses, approves and submits to the Liaison Committee results obtained within the Working Parties.

Working Parties or Task Groups

The Working Parties consists of about 10 active members. They are selected by the Board, in consultation with the Working Party. Working Parties meet twice a year on the average, set up and carry through their working programme, in collaboration with the Board. The Reporter organises the work of the Working Party, issues invitations for, and chairs the Working Party meetings, and maintains close contacts with the Board. The Reporter on behalf of the Working Party informs the Board of work both executed and planned.

Presently the JCSS has three Working Parties (WP’s) and one Task Group (TG). The WP’s are set up around activities which are of permanent character. The TG’s are initiated for activities which are assumed to have a more limited duration. However TG’s may transform to become WP’s if it turns out to be relevant.

The present WP’s and the TG of the JCSS are:

WP1: The Probabilistic Model Code (PMC)
The main objective of this WP is to maintain, update and further develop the PMC of the JCSS. The PMC provides the bases for reliability based design of structures in terms of philosophy, general principles, models and methods. The PMC may be utilized in the context of establishing semi-probabilistic design codes for structures as well as for reliability based design of specific project.
WP2: Risk Informed Decision Support for Systems Involving Structures
The main objective of this WP is to provide bases for risk informed decision support for the design and management of systems involving structures. Focus is directed on the rationale for optimizing decisions, probabilistic system representations in the context of natural and manmade hazards, principles for modeling of consequences, acceptability and criteria regarding safety of humans as well as the qualities of the environment together with risk perception and management of risk communication.
WP3:
The JCSS Continuing Education and Advanced School
This WP has the objective to disseminate the knowledge established within WP1 and WP2 as well as to share the experience of the members of the JCSS and other international subject matter experts in the network of the JCSS. The target groups for the JCSS dissemination activities are professionals from the industry and public authorities with an interest to upgrade their knowledge as well as PhD students. Specific information may be found here.
TG1: The JCSS Special Task Force on Resilience and Sustainability in the Built Environment.
The mandate of the special task force is to assess and map the role of structural design concepts in the context of sustainable and resilient societal developments, to identify frameworks and methods for assessing sustainability and resilience of structural concepts and to propose strategies for regulation of structural design with joint consideration of structural safety, sustainability and resilience.

       

Selection Procedures

The President is nominated by the Board and needs endorsement by the Liaison Committee at least half a year before expiring the current presidents term. The Reporters are nominated by the relevant Working Party and needs endorsement by the Board. Each association is responsible for the nomination of its own Board member. Members of a Working Party are nominated by the Working Party and need endorsement of the Board.
