Determining the role of earthquake in the amount of damage caused to concrete structures

Earthquake hazards are direct effects such as fault rupture, earthquake, soil liquefaction and indirect effects such as tsunamis, floods, landslides and fires. Each of the above effects can play an important role in building damage and affect the level of performance in the building. The area near the fault is usually assumed to be within 15 km of the active fault. Fragility curves are one of the useful tools for evaluating the probability of structural failure. In this study, the role of earthquake in the amount of damage caused to concrete structures has been investigated. In concrete buildings, due to the fact that humans have an essential role in making concrete, which is considered the main material and structure in this type of buildings, so by failing in any of the steps of concrete preparation, including the type and material of selected materials, granulation, Excessive ratio of water to cement or any such items that ultimately lead to a reduction in the expected strength of the concrete design, can cause structural weakness in the building.
