Control Performances of Friction Pendulum and Sloped Rolling-Type Bearings Designed with Single Parameters

open access: yesApplied Sciences, 2020
Owing to quite different features and hysteretic behavior of friction pendulum bearings (FPBs) and sloped rolling-type bearings (SRBs), their control performances might not be readily compared without some rules.

Seismic Response of RC Frames with a Soft First Story Retrofitted with Hysteretic Dampers under Near-Fault Earthquakes

open access: yesApplied Sciences, 2021
Reinforced concrete (RC) frame structures with open first stories and masonry infill walls at the upper stories are very common in seismic areas. Under strong earthquakes, most of the energy dissipation demand imposed by the earthquake concentrates in ...

Probabilistic sensitivity analysis of two suspension bridges in Istanbul, Turkey to near- and far-fault ground motion [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2012
Abstract. The aim of this paper is to compare the near-fault and far-fault ground motion effects on the probabilistic sensitivity dynamic responses of two suspension bridges in Istanbul. Two different types of suspension bridges are selected to investigate the near-fault (NF) and far-fault (FF) ground motion effects on the bridge sensitivity responses.

Seismic Behaviour of a Single Span Historical Masonry Bridge

open access: yesJournal of Materials and Engineering Structures, 2023
A major portion of the cultural heritage consists of old structures that are susceptible to earthquakes. These structures are prone to significant damage from natural disasters, particularly earthquakes.

Evaluation of the accuracy of traditional Pushover methods in regular RC structures [PDF]

open access: yesمدل‌سازی پیشرفته در مهندسی عمران
In the traditional pushover method, which has been the noticed by seismic design code, only the effect of the first vibration mode of the structure is considered, reducing the accuracy of the results, especially in mid-rise and high-rise structures.

Effects of Near Fault and Far Fault Ground Motions on Nonlinear Dynamic Response and Seismic Improvement of Bridges

open access: yesCivil Engineering Journal, 2018
In this study, the dynamic response of bridges to earthquakes near and far from the fault has been investigated. With respect to available data and showing the effects of key factors and variables, we have examined the bridge's performance. Modeling a two-span concrete bridge in CSI Bridge software and ability of this bridge under strong ground motion ...

Fragility Assessment of a Long-Unit Prestressed Concrete Composite Continuous Girder Bridge with Corrugated Steel Webs Subjected to Near-Fault Pulse-like Ground Motions Considering Spatial Variability Effects

open access: yesBuildings
Prestressed concrete composite girder bridges with corrugated steel webs (PCCGBCSWs) are extensively employed in bridge construction because of their low dead weight, fast construction, and high prestressing efficiency.
