TAILIEUCHUNG - A study on safety of reconstructed regions after 1990 Rudbar-Manjil earthquake in Iran

The results indicate that two decades after the event, more than 80% of the existing buildings are still seismically vulnerable, which shows that recovery efforts has failed to improve the region’s safety. In this investigation, to establish a safe development culture in future disasters, it is proposed to have a pre-designed recovery plan with the following strategies: 1) Maximum use of local construction technology and technique in the recovery stage; 2) Designing a comprehensive and steady educational program to teach the safe and new methods of reconstruction to local workers; 3) Creation and promotion of an effective system of supervision. | JSEE Vol. 19, No. 1, 2017 A Study on Safety of Reconstructed Regions after 1990 Rudbar-Manjil Earthquake in Iran Kiarash Nasserasadi Assistant Professor, University of Zanjan, Zanjan, Iran, nasserasadi@ and Member of Iranian Earthquake Engineering Association Received: 16/03/2015 Accepted: 28/02/2017 ABSTRACT Keywords: Collapse Margin Ratio (CMR); Incremental Dynamic Analyses (IDA); RC Frames; Iranian Seismic Standard Recovery and post-recovery stages are crucial parts of a risk management system to achieve several objectives: to return the affected area to pre-disaster stage after the catastrophe, to organize essential elements for the prevention of the next disaster, and to increase the capacity of the society. It is important to evaluate the functionality of this stage in any reconstruction program. This paper makes an effort to study the long-term results of reconstruction and recovery (recovery for short) efforts after 1990 Rudbar-Manjil Earthquake in Iran. It evaluates both the vulnerability of the existing buildings and, based on that, the region’s safety. Two separated analyses have been used for the evaluation of buildings’ vulnerability: 1) survey of random buildings, and 2) the regional analysis. The results indicate that two decades after the event, more than 80% of the existing buildings are still seismically vulnerable, which shows that recovery efforts has failed to improve the region’s safety. In this investigation, to establish a safe development culture in future disasters, it is proposed to have a pre-designed recovery plan with the following strategies: 1) Maximum use of local construction technology and technique in the recovery stage; 2) Designing a comprehensive and steady educational program to teach the safe and new methods of reconstruction to local workers; 3) Creation and promotion of an effective system of supervision. 1. Introduction Recovery after a disaster is an important issue in seismic risk reduction programs .
