A Terminology and Procedures Sub-Committee was created to focus on definitions of terms and to develop a conceptual framework. The Sub-Committee prepared a draft that was discussed and accepted in principle by the Committee at its meeting on 13 May 2010. The draft is published here in its latest but shortened version for rapid dissemination and discussion. The complete draft is available on request. The draft starts with a comprehensive and consistent set of definitions of relevant terms such as collapse resistance, robustness, vulnerability, exposure, direct design, indirect design, threat-specific design, non-threat-specific design, and many more, which up to now have not been consistently defined and used. These definitions are strongly cross-referenced and a hierarchical system of interrelated definitions thus emerges. On this basis, a conceptual framework of design criteria comprising design requirements, design objectives, design methods, and verification procedures is developed. This framework will serve as the outline for the Committee's design guidance document. Specific content for a number of sections and an appendix still need to be developed by dedicated Sub-Committees (SC). These tasks are clearly defined by the framework. The draft consists of recommendations and commentary. In the following, recommendations are set in normal font and commentary in italics. The section numbering of the draft is substantial to cross-referencing and thus retained. Specific content still to be developed by dedicated Sub-Committees is indicated in brackets. Numbers given in tables are intended to illustrate the possible final content of these tables and to stimulate discussion. They should be understood as placeholders for the final content to be specified by the respective Sub-Committee. © ASCE 2011.enHausbau, BauhandwerkArchitekturConference Paper10.1061/41171(401)182Conference Paper
