Response analysis of hollow core slab bridge with different column heights to near-fault seismic motions. [PDF]

JES: Journal of Engineering Sciences
The near-fault earthquake motions are characterized by influential velocity impulses, and remarkable permanent displacement. Such unique characteristics can substantially change the induced seismic responses of structures.

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

Buildings
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.

Near-field ground motion intensity parameters of the major February 06, 2023, Türkey Kahramanmaraş earthquake sequences

Geohazard Mechanics
Türkey is located in a seismically active region where the Anatolia, Africa, and Arabia tectonic plates converge. The high seismic hazard causes the region to be repeatedly struck by major earthquakes.

Seismic Fragility of Fixed and Flexible Base RC Bridge under Near-Fault Directivity Effects

Journal of the Civil Engineering Forum
Reinforced Concrete bridges are widely used in highway infrastructure due to their cost-effectiveness and structural redundancy. However, they are highly vulnerable to seismic hazards, particularly in near-fault regions where ground motions exhibit ...

Seismic responses of isolated bridges subjected to near-fault ground motions: simple pulses vs. whole records

Frontiers in Built Environment
Velocity pulse with strong energy input is the significant feature of near-fault ground motions. Bridges close to or passing across seismic faults may suffer from higher failure risk, which is inseparable from the influence of velocity pulse.

Study of Response Characteristics and Strength Parameter Evaluation of Water Intake Tower Under Different Amplitude Modulation Modes

Buildings
This study selected a simplified water intake tower model, simplifying the physical structure into a cantilever model, and MATLAB software (R2010b) was used to develop a rapid seismic response analysis program for the structure.
