General report on local ductility

2001

The current seismic design philosophy for reinforced concrete structures in New Zealand is based on the concept that it is generally uneconomical to design a building to ensure elastic response in a large earthquake. An implication of this concept is that structural damage is accepted, as long as collapse is prevented in a major earthquake. For this reason standards allow the use of design forces that are generally smaller than those required for elastic response. This requires the critical regions of the structure to be adequately designed for ductility and for energy dissipation. In New Zealand, ductile design has been achieved since 1976 by selecting a suitable mechanism of plastic deformation and ensuring, through capacity design, that the mechanism can develop and be maintained. Experience gained from earthquakes abroad indicates that the cost of repair of buildings designed for ductile response has not been insignificant. This prompts the need to develop structural systems tha...

Modern society requires that structures exhibit higher levels of resilience, especially under earthquakes. The measure of resilience can adequately reflect a city’s capacity to withstand disasters. Quantitative results of seismic resilience assessments in the pre-earthquake environment can further support emergency response planning and seismic retrofits strategies. Thus, the seismic resilience of civil structures is gaining increasing interest as a special approach that goes beyond design codes. Resilience is the ability to absorb or avoid damage without experiencing complete failure, and should be the goal of design, maintenance and restoration of buildings and infrastructures. Mitigating structural damage to infrastructure under such seismic motions remains a major challenge. The continuous development of new materials, novel analysis techniques, design concepts, and numerical analysis tools presents promising advances that could help the research community and designers overcome design and implementation challenges in creating resilient structures. This Special Issue is focused on recent advances in structural analysis and seismic resilience within civil engineering. We welcome articles that focus on the latest developments in innovative techniques and solutions for structural analysis, seismic resilience, seismic hazard resilient structures, performance-based design, and innovative structural systems for earthquake-resilient buildings. The collection will be of interest to academics and structural and construction engineers but also architects and other professionals involved in the building and construction fields. The submission of original research studies, review papers, and experimental and/or numerical investigations focused on the structural analysis and seismic resilience of buildings and infrastructures is warmly encouraged. Both new projects/applications and interventions on existing structural systems will be of interest for the Special Issue. Contributions on the following topics are welcome. Potential topics that fall in the scope of the research topic include, but are not limited to, the following: Advanced composite materials for retrofitting Analysis of constructional materials under seismic loads Damage detection and condition assessment Damage limitation design and life-cycle sustainability Innovative practices in seismic-resilient structural design Innovative structural systems for damage minimization and recoverability after earthquakes Integrated techniques for the seismic retrofitting and strengthening New structural systems for resilient structures Performance-based seismic design of structures Seismic hazard and risk-mitigation measures Multi-level seismic performance of critical infrastructures under design-basis earthquakes and maximum-credible earthquakes Seismic resilience assessment Seismic safety assessment and retrofit of existing structures Seismic vulnerability assessment of structures Structural health monitoring Structural vibration control Vibration analysis and dynamic characterization Prof. Dr. Shehata E.

During over three and a half year, five E uropean universities collaborated with an European steel producer in order to analyze the behaviour of composite structures under earthquake action from a common E uropean point of view. This international cooperation, which in our minds gives already a taste what can be the E uropean Community of tomorrow, became only possible by the generous sponsorship of C.E.C., the Commission of the European Community. Therefore, we want to acknowledge first of all the important financial support from the Commission of the E uropean Community, as well as the moral support given to this research by the E CSC E xecutive Committee F6 "Steel Structures", former committee F8 "Light Weight Structures". Special thanks are due to the scientific contributors to this research, namely: ■ Prof. SE DLACE K, Dipl. Ing. KUCK and Dipl. Ing. HOFFME ISTE R from the RWTH Aachen ■ Prof. BOUWKAMP, Dipl. Ing. SCHNEIDER and Dipl. Ing. KANZ from the TH Darmstadt, ■ Dr. Ir. PLUMIER and Dipl. Ing. TUNHUS from the University of Liège, ■ Prof. BALLIO from the Politecnico di Milano and ■ Prof. KLINGSCH, Dipl.

This document provides recommended criteria for the design of steel moment-frame buildings to resist the effects of earthquakes. These recommendations were developed by practicing engineers, based on professional judgment and experience, and by a program of laboratory, field and analytical research. While every effort has been made to solicit comments from a broad selection of the affected parties, this is not a consensus document. It is primarily intended as a resource document for organizations with appropriate consensus processes for the development of future design standards and building code provisions.

Earthquake zones cover a significant part of our earth, therefore, when planning and designing residential areas, factories, or other human establishments, professionals have to take into account the seismic hazard of that area. The current earthquake standard in Romania is based on the European code. This paper presents, beside the most significant structural composition rules, the applicable methods that can be used to ensure sufficient load bearing requirements.
