Seismic vulnerability assessment of precast post-tensioned segmental bridge piers subject to far-fault ground motions [PDF]

open access: yesStructures, 2021
Abstract Precast post-tensioned segmental (PPS) bridge piers mitigate global and local damages of bridge structures through natural hinges (joints between their segments) and rocking motion of their segments. The application of the PPS piers is currently growing in Accelerated Bridge Construction (ABC) where the segments are manufactured offsite with

Estimation of Floor Response Spectra for Self-Centering Structural Systems with Flag-Shaped Hysteretic Behavior

open access: yesBuildings, 2022
Spectral floor-acceleration demands are necessary for the seismic design of acceleration-sensitive non-structural components (NSCs). Existing studies to estimate floor response spectra (FRS) using empirical equations are based on elasto-plastic and ...

Incremental Dynamic Analysis of Mid-Rise Buildings with Buckling Restrained Brace Frame System under Pulse-Like Near-Fault Ground Motions [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering
Buckling Restrained Braced Frames (BRBFs) are frequently utilized as seismic force-resisting systems due to their considerable ductility and energy dissipation capacity.

Estimating Maximum Rotation of Beam of R.C. Moment‐resisting Frames Using Equivalent Pulses of Near-fault Motions [PDF]

open access: yesمجله مدل سازی در مهندسی, 2017
Seismic events all over the world have shown that ground motions in vicinity of causative faults (within a distance of 15 km from the fault) may be categorized as large-velocity pulse and large-displacement fault which have the potential to cause ...

Comparative Evaluation of Behavior Factor of SMRF Structures for Near and Far Fault Ground Motions

open access: yesPeriodica Polytechnica Civil Engineering, 2016
In common design codes, earthquake loads are reduced by a coefficient (behavior factor) which depends on nonlinear seismic performance of structure during earthquake event. Nonlinear performance of structures depends on structural properties and ground motion characteristics.

Synthesis of Near-fault Ground Motion Using a Hybrid Method of Stochastic and Theoretical Green’s Functions

open access: yesFrontiers in Built Environment, 2016
The effect of near-fault ground displacement is a significant factor when structures straddle a fault, because the fault produces both static step-like deformations and dynamic pulse-like ground motions. It has been observed that the static displacements

Evaluation of 3D Nonlinear Earthquake Behaviour of the Ilısu CFR Dam under Far‐Fault Ground Motions

open access: yesAdvances in Civil Engineering, 2019
In the recent times, many huge concrete face rockfill dams (CFRDs) have been modelled and constructed in the world, and many of these dams are located on the strong earthquake zones. Examination of the seismic behaviour of a CFR dam built on the seismic zone is very important to assess the safety and future of the dam.

Quantitative bounded method of special long-period ground motions

open access: yesMagazine of Civil Engineering, 2022
The resonance effect of special long-period ground motions to (super) high-rise buildings is significant, which is likely to cause serious damage to these long-period structures. Therefore, the influence of long-period ground motions cannot be ignored in

Evaluation of seismic parameters of steel moment resisting frames based on “FEMA P-695” under near-field rotated ground motion [PDF]

open access: yesJournal of Structural and Construction Engineering, 2016
Behavior factor (R) is one of the seismic design parameters that considers nonlinear performance of structures during an earthquake. In most of the seismic design codes, behavior factor has been used for considering nonlinear performance of structures in
