Profile

Soheil got his BSc in Civil Engineering from Urmia Technical University (Iran) in 2012 and his MSc in Structural Engineering at Istanbul Technical University (ITU, Turkey) under the supervision of Prof. Alper Ilki. In his dissertation, he investigated the “Strengthening of low-strength short concrete columns with sprayed-up textile reinforced GFRC”. During his studies at ITU, he also performed numerous tests at the Structural and Earthquake Laboratory to investigate the effectiveness of basalt reinforced GFRC jackets, including a comprehensive experimental programme on small, medium and full scale components strengthened with GFRC. He was heavily involved in a joint ITU-ISTKA project on “Determination of the Seismic Performance of the Existing Buildings by Full Scale Tests” that tested an real building on site (http://www.seismictest.itu.edu.tr/en/). He was part of the design team at MBYT Engineering Co. Turkey (www.mby-e.com) until he joined the Concrete and Earthquake Engineering (CEE) Group in July 2017. He is the Project Manager of two ongoing Newton Fund projects related to his research on “Rapid Earthquake Risk Assessment and Post-Earthquake Disaster Management Framework for Substandard Building in Turkey” and “Post-Earthquake Disaster and Risk Management Through a Rapid Response Framework for Industrial Zones in Turkey”.

Recent activities and achievements

Project title:

Seismic Vulnerability of Substandard Reinforced Concrete Buildings and Risk Assessment.

Objectives:

  1. Develop of analytical model using OpenSees considering the deficiencies and existing of infill walls of substandard RC buildings.
  2. Derive dynamic vulnerability curves for different classes of RC buildings
  3. Derive upgraded vulnerability curves for retrofitted RC buildings

Tasks and Methodology:

Data collection and Numerical Study:

1- Data collection to determine deficiencies to be considered in analytical model and classification of building stock in Marmara (Turkey)

2- Validation of analytical model using experimental results.

3- Derivation of vulnerability curves for typical classes of RC buildings for Marmara.

4- Proposal of possible efficient strengthening and retrofitting techniques by taking into account the structural elements material quality and detailing.

5- Validation of selected strengthening solutions with large scale cyclic loading tests and shake table tests with analysis, and derivation of upgraded vulnerability curves by using strengthening solutions.

Expected Results:

This research will enhance the capabilities of existing ERA Frameworks developed previously at UoS. This research will also recommend dynamic vulnerability curves to be included in the next generation of seismic assessment guidelines, especially for earthquake-prone developing countries.

Research project(s)

Rapid Earthquake Risk Assessment and Post-Earthquake Disaster Management Framework for Substandard Buildings in Turkey

Substandard structures account for a large proportion of the building stock in many large urban areas of developing countries. Such highly vulnerable structures have experienced catastrophic damage during major earthquakes in the past, leading to extensive human, economic and societal losses. For instance, the 1999 Kocaeli earthquake that hit Marmara...

Post-earthquake Disaster and Risk Management through a Rapid Response Framework for Industrial Zones in Turkey

The Concrete and Earthquake Engineering (CEE) group secured a Newton Fund Institutional Links grant for a two-year project on ‘Post-earthquake Disaster and Risk Management through a Rapid Response Framework for Industrial Zones in Turkey’. Catastrophic damage to industrial facilities during the 1999 Kocaeli earthquake caused extensive fires and environmental pollution...
