Assessment of Soft-First-Floor Structures Reinforced by Rocking Frame Based on Seismic Resilience

Buildings
As a no-disturbance integrated-retrofitting technique, an external rocking frame was widely used on reinforced concrete (RC) structures. Yet, with the increasing demand for seismic strengthening of existing buildings, it has become a concern to evaluate ...

Seismic Isolation of Fragile Pole-Type Structures by Rocking with Base Restraints

Buildings
Pole-type structures are vulnerable to earthquake events due to their slender shapes, particularly porcelain cylindrical equipment in electrical substations, which has inherent fragility and low strength in its materials.

Seismic Performance Analysis of Tuned Mass Rocking Wall (TMRW)-Frame Building Structures

Buildings, 2021
A tuned mass rocking wall (TMRW) is a passive control device that combines the merits of a traditional tuned mass damper (TMD) and a traditional rocking wall (RW).

Physics-informed artificial intelligence models for the seismic response prediction of rocking structures

Data-Centric Engineering, 2023
The seismic response of a wide variety of structures, from small but irreplaceable museum exhibits to large bridge systems, is characterized by rocking. In addition, rocking motion is increasingly being used as a seismic protective strategy to limit the ...

Dynamic Analysis of Resilient Rocking Wall Structures: A Numerical Study on Performance Demands

Buildings
Dynamic time history analysis has long been regarded as an acceptable and reliable method for the seismic design of structures. The methodology for conducting such analyses, particularly for modern structures with advanced seismic resisting systems, is ...

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.
