Improving Seismic Resilience of Reinforced Concrete Structures

Mission Statement/Objectives
Provide a platform to exchange knowledge and provoke understanding in earthquake resilient design, vulnerability, and strengthening techniques for existing reinforced concrete structures.

Scope & Limitation

TG1.1 is focused on improved earthquake resilient structural design and on seismic strengthening and retrofitting strategies aimed towards earthquake resistant reinforced concrete structures.

The main scope of this task group is to collect and evaluate codes for the strengthening and retrofitting of reinforced concrete structures, to develop practical guidelines for the design of strengthened elements and structures, and to work towards the development of novel strengthening techniques focusing on resilience, robustness, durability and sustainability.

The following outputs which were produced during the previous term of TG1.1 (2018-2023) will be used as background documents for the upcoming activities of the group:

· ‘Characteristic Seismic Failures of Buildings’ (SED 16 IABSE Bulletin)

· ‘Case studies on Conservation of Structures and Seismic strengthening / retrofitting of Existing Structures’ (Case Studies 2 IABSE Bulletin)

· ‘Seismic Isolation and Response Control’ (SED 19 IABSE Bulletin)

· ‘Code comparisons for the design of seismic resilient structures’ document (Internal Report)

Expected Project Output

TG 1.1 is established in order to provide advice and support activities for the mitigation and reduction of seismic risk, to produce research outputs in the field of seismic strengthening, to organise special sessions and workshops, to produce design guidelines and to provide a forum to link practitioners with researchers in addition to the education of engineers. 

· Curriculum on ‘Earthquake Engineering’ as part of the IABSE ACADEMY.

· ‘Code comparisons document’ for consideration for potential publication as SED.

· Special session in the IABSE Tokyo conference in May 2025.

· Research paper on the use of novel high-performance concrete/materials for the strengthening of existing structures.

· Research paper on the evaluation of different strengthening techniques for reinforced concrete structures.

· Research paper on the use of non-destructive techniques for the detection of defects of RC structures.

· Research paper on the evaluation of numerical methods for resilience quantification of RC structures.

· Design guidelines for RC elements strengthened with additional concrete layers and jackets.

· A forum through a dedicated website (in addition to webinars) to link practitioners and researchers and provide the most up-to-date information in this field and disseminate TG1.1 activities.

Start Date: January 2024

Target Date of Completion: January 2028
