Application of visco-hyperelastic devices in structural response control
Structural engineering has progressed from design for life safety limit states to performance based engineering, in which energy dissipation systems in structural frameworks assume prime importance. A visco-hyperelastic device is a completely new type of passive energy dissipation system that not …

Advanced Seismic Design of Innovative Precast Systems for Structural Response Control
… reflect intrinsic energy dissipation capacity of structural elements. The key concept is the reduction of the structural cost, from the point of view of the initial cost, for design under moderate or important earthquake levels assuming possible damages at structural and non structural elements …

Evaluation of Structural Response and Damage Resulting From Earthquake Ground Motion
… design of structures to limit or preclude strong response and damage from earthquake ground motion is a complex problem and is the subject of this thesis. The factors leading to strong response are not well understood and clearly involve more than peak acceleration and yield level. Present methods …

Hydor-impact, fluid-structure interaction and structural response of modern racing yacht
… a result, many yachts have experienced various structural<br/>failures caused by the hydrodynamic impact or ’hydro-impact’ phenomenon by<br/>slamming.<br/><br/>The structural failure by hydro-impact originates from the facts that the external<br/>hydro-impact load and fluid structure interaction …

Using Pulse R -Factors to Estimate Structural Response to Earthquake Ground Motions
… new method is developed for estimating inelastic response to strong ground motions. The method applies strength reduction (R) factors determined for a simple pulse to the elastic spectrum of the ground motions to estimate inelastic response spectra. Optimal pulse shapes and durations are …

A method for determining the number of dominant modes in sinusoidal structural response
… behavior of structures. In modal analysis, the response of a structure at a given frequency of excitation is represented as the summation of the contributions of a 11 the modes of vibration. Although continuous structures have an infinite number of modes, only a few of them are present to a …

Computational Study of Highway Bridges Structural Response Exposed to a Large Fire Exposure
… to produce excessive damage onto highway bridge structural elements including complete collapse of the infrastructure. The occurrence of a fire beneath a bridge can lead to significant economic expense and loss of service even if the bridge does not collapse. The focus of the current research is …

The structural response of steel I-section members subjected to elevated temperature gradients across the section
This work is primarily concerned with the structural response of steel I-section beams and columns heated along one flange to the elevated temperatures likely to be reached in real fires in buildings or ISO 834 fire resistance tests. Experiments have employed nominally full size models, heated …
