چکیده
The damping ratio is an important parameter in dynamic analyses and plays a key role the design of building structures. Elastic response spectra are widely used this to describe earthquake action specific site classes. 5% damped generally for most conventional However, other types structures may not have can much lower or larger ratios. recommended at about concrete whereas it estimated 2% steel Tall slender buildings ratios low-rise be designed using than 5%. For these buildings, elastic modified account different levels This study proposes modification factors (DMFs) which computed as benchmark. A strong ground motion set has been selected stiff class displacement, pseudo-velocity, pseudo-acceleration single-degree-of-freedom (SDOF) systems. DMFs obtained terms 3%, 10%, 20%, 30% considered. Variations with graphically. It seen from results that sensitive vibration period SDOF system.

Uncertainty Analysis of Identified Damping Ratios in Nonlinear Dynamic Systems
Obtaining accurate estimates of damping parameters from experimental measurements of structures has been a challenge in the civil engineering community. In general, the confidence level on the identified damping is much lower than that of the identified natural frequencies and mode shape components. Most system identification methods are based on linear system and control theories, while in rea...

متن کاملDamping factors for the gap-tooth scheme
An important class of problems exhibits macroscopically smooth behaviour in space and time, while only a microscopic evolution law is known. For such time-dependent multi-scale problems, the gap-tooth scheme has recently been proposed. The scheme approximates the evolution of an unavailable (in closed form) macroscopic equation in a macroscopic domain; it only uses appropriately initialized sim...
