A Simple Response Evaluation Method for Base-Isolation Building-Connection Hybrid Structural System under Long-Period and Long-Duration Ground Motion

Frontiers in Built Environment, 2018
An innovative hybrid control building system of base-isolation and building-connection has been proposed in the previous study. This system has two advantages, (i) to resist an impulsive earthquake input through the base-isolation system and (ii) to ...

OPTIMAL DESIGN OF INERTIAL MASS DAMPER FOR SDOF ELASTIC-PLASTIC BUILDING STRUCTURES SUBJECTED TO LONG-DURATION EARTHQUAKE GROUND MOTIONS

Journal of Structural and Construction Engineering (Transactions of AIJ), 2022
Tuned mass dampers exhibit high performance when optimally tuned to a structure. However, their damping performance decreases once the natural period of the structure is elongated due to the elastic-plastic response under strong earthquakes.

Study on Quasi-Static Loading Protocols considering the Action Characteristics of Long-Period Ground Motions

, 2021
Due to abundant low-frequency components of long-period ground motions (LPGMs), long-period structures are susceptible to severe damage. The corresponding time-history displacement responses have significant “large-displacement” and “long-duration ...
