The Seismic Resilience Index (SRI) quantifies post-earthquake building recovery time for reinforced concrete structures in Malaysia. This approach aids decision-makers in selecting cost-effective retrofitting solutions to enhance seismic safety and sustainability.
Area of Science:
- Civil Engineering
- Earthquake Engineering
- Structural Engineering
Background:
- Numerous quantitative frameworks exist to assess earthquake resilience.
- The time dimension is crucial for understanding post-seismic recovery phases.
- Existing reinforced concrete (RC) structures require robust evaluation methods for seismic resilience.
Purpose of the Study:
- To examine the seismic resilience of existing RC structures in Malaysia under far-field (FF) and near-field (NF) earthquake scenarios.
- To implement the Seismic Resilience Index (SRI) and functionality curve for assessing building recovery.
- To evaluate the SRI for diverse RC building typologies and present results using GIS.
Main Methods:
- Non-linear dynamic analysis (NL-DA) and non-linear time history analysis (NL-THA) using Finite Element (FE) platforms.
- Selection of seismic records for FF and NF scenarios.
- Application of Incremental Dynamic Analysis, fragility, vulnerability, and functionality assessments.
Main Results:
- SRI was implemented on four-story RC school and five-story RC hospital buildings damaged by the 2015 Ranau earthquake.
- SRI was evaluated for 25 existing RC structures categorized into low, mid, and high-rise clusters.
- Graphical results were presented using a Geographical Information System (GIS) platform.
Conclusions:
- SRI assists decision-makers in proposing repair or retrofitting solutions with manageable recovery times and costs.
- The approach helps mitigate impacts on lives, property, and the economy.
- Enhancing structural sustainability and serviceability ensures seismic safety and contributes to Sustainable Development Goal 11.
