Question

Why viscosity is considered as dynamic property in model analysis?

Answer 1

Viscous damping properties have been required in order to predict the accurate earthquake response of building

structures. Static loading tests, free vibration tests, and shaking table tests were executed with several small

scaled structures as specimens, and an evaluation formula for the viscous damping force was proposed in

proportional to the response acceleration. A pseudo-dynamic test of the identical specimen was carried out

utilizing the proposed formula in order

to confirm the accuracy of simulated dynamic response.
