Накратко на български
Новите методи за проектиране на стоманени конструкции разглеждат сградите като цялостни системи, вместо като отделни греди и колони. Това позволява по-бързо и ефективно строителство с устойчиви материали, като същевременно се спазват европейските стандарти за безопасност.

New Generation Design Methods for Stainless Steel Structures
Current structural design methods consider structural systems, such as frames, as a set of independent beams, columns, and connections, with very little consideration for the interaction between them, and the resistance of each member is checked independently. This design procedure is complex and time consuming, and often underestimates the resistance of structures, severely limiting the efficiency with which our cities and infrastructures are built. In these uncertain times when societies need to be more resilient and efficient than ever, it is fundamental to develop advanced and highly optimised design methods, and to use sustainable construction materials such as stainless steel under the consideration of life-cycle cost strategies. Thanks to recent advances in structural analysis software, it is now possible to accurately predict the behaviour of complex structural systems and to switch to more holistic design methods that consider structures as complete systems in a more integral way. In other words, it is now possible to change the paradigm of structural design. These new methods are known as the Direct Design Methods (DDM), and allow a faster, simpler, safer and more efficient design of structures, but they were not available to structural engineers in the European structural codes until very recently. Thanks to the NewGeneSS project, the DDM has been extended to Europe, and design recommendations have been developed for stainless steel structures to ensure that the safety requirements mandated by policy makers are met through the calibration of safety factors. This project is a joint effort between the Universitat Politècnica de Catalunya, the University of Sydney and Pedelta S.L., and has built the basis of the next generation of European structural design standards. This will, in turn, encourage innovation and help European design offices to mobilize their whole range of capabilities and assets, strengthening international collaboration and the transfer of knowledge to industry and society.

Цел на проекта
Current structural steel design codes are based on traditional limit state criteria, in which uncertainties are accounted for through partial coefficients when checking members and connections. However, within the frame of resilient and sustainable cities, it is necessary to choose optimised and sustainable construction materials such as stainless steel, as well as to accurately predict the behaviour and failure of structures by means of system-based design approaches. One method that fits these criteria is the Direct Design Method (DDM). Its applications span from the optimized design of new structures to the safety assessment of existing ones (for reutilization or evaluation after possible damage due to time-degradation or intentioned harm). The DDM directly evaluates the system’s strength from finite element analysis without requiring member and connection checks, thus leading to the design of safer, lighter, more economic and potentially faster designs. More importantly, failure modes of the structure are apparent, making it possible to consider the consequences of failure in design and achieve a consistent system reliability. However, there is a need for research to develop system resistance factors based on rigorous system reliability considerations for the DDM, specially for stainless steel. This research project will develop the bases for the system-based New Generation Design Methods for stainless steel structures, and this fellowship will provide a most adequate training in structural reliability for the development of the pioneering DDM for stainless steel structures and the corresponding design recommendations for their inclusion in the Next Generation European Standards. It will be an international and inter-sectorial effort to provide designers with powerful tools that can encourage innovation in design, in addition to enhancing the transfer of knowledge and strengthen research ties not only between Australia and the EU, but also with the industry.
