Chloride-induced corrosion is one of the most important causes of the strength degradation of reinforced concrete (RC) bridges. As the piers of RC bridges are important elements for sustaining lateral loads, corrosion of pier columns may lead to sign

One of the main components for the development of regional seismic risk models is the fragility functions for common building types. Due to the differences between the national design codes, construction practices, and construction materials, it is n

Modern seismic codes employed the uniform hazard basis for seismic design, which defines design ground motion with a fixed return period for different sites. Seismic design for uniform hazard ground motion does not lead to the goal of uniform structu

Iran is located in a very high seismic zone. The current national code of design of buildings referred to as Standard No. 2800 (STD-2800) employs the design-basis earthquake (DBE) based on the uniform hazard philosophy. New generations of seismic cod

In this study, the effects of the vertical ground motion component (VGMC) of near-fault records on the structure as well as sliding-rubber bearings have been investigated. For this purpose, a highway bridge with sliding-rubber hybrid isolators was mo

Negative stiffness has shown a capable characteristic in reduction of seismic response of structures. In this paper a passive Rotating Mass Damper (RMD) with negative stiffness characteristic, which was conceptually introduced in an earlier study, ha

Petrochemical plants and industrial facilities have shown high vulnerability during the past earthquakes like Kobe (Japan, 1995), Izmit (Turkey, 1999), Gujarat (India, 2001), Tokachi-Oki (Japan, 2003) and other earthquakes. As more than 50% of the pe

The ductility capacity of bridge piers is estimated uniaxially by moment-curvature analysis, regardless of the amount of flexural demand on the perpendicular axis of the section. In this study, by applying a numerical fiber-based model, the ductility
