Any reduction in the performance of bridges, as one of the important components of transportation facilities, might lead to significant direct and indirect economic losses and casualties to communities, which should not be underestimated. This paper presents a case study on a major bridge in the metropolis city of Tehran, Iran, and adopts a compreh...
Article
Due to the fact that Iran is located in one of the most earthquake-prone areas throughout the world, it is of great importance to pay specific attention to the performance of healthcare facilities after the occurrence of an earthquake to identify how they would serve patients and potential victims during and after the seismic events. Health centers...
Article
The performance of Reinforced Concrete (RC) structures, as one of the most widely used structures in civil engineering , during its useful life is always affected by various deterioration factors such as chloride corrosion, and can lead to irreparable financial and human losses. Therefore, in this study, the effects of chloride corrosion on the sei...
Article
Rapid assessment of the resilience and vulnerability of critical structures and infrastructures is necessary to prepare stakeholders and decision-makers for risk mitigation during future catastrophic events. The current study developed a web- based software tool called a Resilience indicator (Ri) that can estimate the seismic resilience index of Ir...
Article
Resilience is a new approach and is defined to promote creating a resilient society against natural hazards. Building cities resiliently against these hazards is crucial in order to reduce vulnerability and for proper risk management during occurrence of accidents. Todays, one of the most important hazards, threatening many cities is the occurrence...
Article
In the present paper, a Monte Carlo-based framework is developed to investigate the accuracy and reliability of analytical fragility curves of steel moment-resisting frames and simple SDOF systems. It is also studied how the effectiveness of incremental dynamic analysis (IDA) and multiple stripes analysis (MSA) approaches, as two common nonlinear d...
Article
After presenting a taxonomy of schools in part one and their modes of behavior during the Ezgeleh earthquake in November 2017, this paper quantifies the seismic resilience index of Iranian school buildings, including post-recovery and retrofitting processes. Six schools having different structural properties as being representative of the 3029 Iran...
Article
Seismic resilience is a new approach in earthquake engineering, which addresses technical, organizational, social, economic, and environmental aspects. The main purpose of a resilience system is to reduce economic or operational casualties, so as to return the community or the damaged system to natural conditions in the shortest possible time. Scho...
Article
Iran is one of the most earthquake-prone areas in the world and the resulting losses and casualties have had long-lasting effects on both its economy and citizens. As a vital structure in any community, schools are expected to maintain their initial functionality during a seismic event to guarantee the safety of students and act as an emergency cen...
Article
Researches have shown that the occurrence and development of corrosion in reinforced concrete structures can lead to the production of materials with a volume multiplied by the initial volume of steel reinforcement bars in concrete. This volume expansion reduces the compressive and tensile strength of reinforced concrete structures and, consequentl...
Article
Schools should be considered as the most important structures in any society, in which children spend plenty of time. As a result, having a proper management of crucial engineering factors such as vulnerability and resilience of schools seems totally vital. The present study intends to deal with this issue in Iranian schools. As a case study, a hig...

An innovative Hybrid Passive Resistive configuration for Truss Girder Frames (HPR-TGFs) is introduced in the present study. The proposed system is principally consisting of Fluid Viscous Dampers (FVDs) and Buckling Restrained Braces (BRBs) as its seismic resistive components. Concurrent utilization of these devices will develop an efficient energy...
Article
One of the important steps in seismic collapse assessment of structures, using nonlinear dynamic analyses, is the appropriate selection of ground motion records. Epsilon (ϵSa), eta (η), and gamma (γ) for long-period structures are proxies recently proposed for Ground Motion Record Selection (GMRS). In this study, two parameters, named γs are propos...

Jack arch masonry slab, developed in the 19th century in Britain has been used widely to floor and roof industrial and residential masonry buildings in many parts of the world. It is still in use in parts of Europe, the Middle East and Indian subcontinent. Taking into account the widespread use of the jack arch flooring and its ease of constructing...

The current paper compares the seismic performance of buckling-restrained braced frames (BRBFs) and ordinary concentrically braced frames (CBFs) through nonlinear static and time history analysis. Two groups of BRBFs and CBFs including 5, 10 and 15 story frames are modeled and nonlinear pushover analysis is carried out. To further investigate the p...

One of the most important undertakings of Iran in reducing the seismic vulnerability of the country against earthquakes is dedication of more than 4 billion dollars to reconstruct the seismically dangerous school buildings and retrofit the vulnerable ones. "Organization for Development, Renovation and Equipping Schools of Iran (DRES)" is the sole o...
Conference Paper
Fragility curves are important elements in the loss estimation procedure since they are very useful instruments to evaluate seismic resilience index. This article tends to investigate the impact of retrotting on reducing the probability of structural failure as well as deriving resilience index in terms of fragility curves. Schools are essential f...
Article
Full-text available
With the progresses made in the field of structural and earthquake engineering and with more exact knowledge gained on seismic behavior of structures, earthquake engineering and various structures have advanced a great deal and various types of analytical methods have been developed for the assessment of structures. Dynamic analysis methods are aim...
Conference Paper
Full-text available
Considering time and budget limitations, implementation of a simple and feasible method for prioritizing retrofitting and demolish/reconstruction projects of school buildings has been and still is one of the most challenges for the responsible organization. In this paper, the factors influencing decision making process for prioritizing retrofitting...
