Due to the lack of advancement in knowledge and technology for earthquake hazard mitigation, this research project is proposed to gather and integrate the strength of the researchers from Japan and ASEAN countries (member and non-member institutions in the region) for formulating a cost-effective and sustainable solution that will build the capacity and empower local community in earthquake disaster prevention and mitigation. The overall goal of this research project is to enhance the knowledge in earthquake hazard assessment and mitigation in low to moderate seismicity countries. The proposed research project has the following specific purposes:
1. To estimate the subsurface structure and vibration characteristics of the ground The damage of structures is often associated to the ground acceleration during earthquake. Soft geological formation in local soil tends to amplify the ground vibration at the site. The dynamic characteristics of the ground are necessarily determined in order to design a safe structure. Microtremor observation is one of the seismic survey techniques that provide convincing prediction of subsurface structure with comparatively less cost and manpower consumption. The damage of structure is then investigated considering the property of the underlying soil.
2. To assess the performance of non-engineered and non-seismically designed buildings and bridges subjected to anticipated earthquake loading Most of the houses affected in the recent earthquakes are the traditional houses and non-engineered houses constructed by the local people without the engineering design. The safety of many of these houses is not assessed by the relevant authorities or agencies. The important buildings which may be designed with certain seismic load stipulated in the design code in Thailand and may not be designed with any seismic action in Malaysia were also damaged by the earthquake. The dynamic response of bridges under earthquake excitation will also be investigated in this study. It is essential to assess the safety of buildings and bridges and the adequacy of the current design practice for structures in low to moderate seismicity regions.
3. To enhance the earthquake resistant design and construction The solution for earthquake disaster prevention in low to moderate earthquake regions will be proposed in particularly in earthquake resistant design and construction of buildings and bridges. The unique solution will be formulated to tailor the needs and constraints of the local community considering the available resources and local common practices.
4. To promote the sharing and collaboration in earthquake hazard reduction and risk mitigation among countries in the region The research team of this project consists of researchers from member institution and non-member institution (in Malaysia, Thailand and Japan) and Malaysian Meteorological Department. The team has the common interest in seismic hazard assessment in low to moderate seismicity regions that will works together for solving common issues on earthquake engineering. This project will also serve as a platform for researchers from both countries to discuss and share their findings in this common issue related to both countries. This will eventually enhance the collaboration in earthquake hazard reduction and risk mitigation among all countries in the region with low to moderate seismicity. (Source: Application to CRC 2016)
