The earthquake-resistant design code provision at the beginning in Japan required that structures resist seismic force produced by response acceleration. The design conce [...]

Rate-independent linear damping, also known as linear hysteretic damping or complex-value stiffness, provides direct control over displacement, a desirable feature for lo [...]

While traditional base isolation remains one of the most widely employed systems for mitigating seismic response, interstory isolation has recently gained popularity, esp [...]

Viscous mass dampers with friction origin force restriction mechanism (force restricted viscous mass damper, hereinafter called FRVMD) are considered for base isolated st [...]

Until now, many researches on optimum design of building structures have been made, and improving performance of computers enabled us to solve large and complicated optim [...]
