Viscous dampers have widely proved their effectiveness in mitigating the effects of seismic action upon building structures. In view large impact that use such dissipative devices is already having and would most likely soon earthquake engineering applications, this article presents a practical procedure for design structures equipped with viscous dampers, which aims at providing tools an easy identification mechanical characteristics manufactured allow to achieve target levels performances....
This article presents the results of an exhaustive parametric analysis which compares performances offered by various systems (which lead to both classical and non damping matrices) added viscous dampers in shear-type structures. The aim research work here presented is identification system maximizes dissipative properties under equal “total size” constraint. choice considered comparison carried out using a numerical approach (based upon use genetic algorithms) physically based classically...
Abstract This paper reports on a series of shaking table tests full‐scale flat‐bottom steel silo filled with soft wheat, characterized by aspect ratio around 0.9. The specimen was 3.64‐m diameter and 5.50‐m high corrugated‐wall cylindrical silo. Multiple sensors were used to monitor the static dynamic response system, including accelerometers pressure cells. Numerous unidirectional performed consisting random signals, sinusoidal inputs, both artificial real earthquake records. objectives...
In this paper the authors investigate dynamic performances of multi-degree-of-freedom shear-type structures equipped with manufactured viscous dampers. The system added dampers that leads to a mass proportional damping (MPD) matrix is identified as one providing best overall performance in terms minimum top-storey response variance Gaussian band limited white noise input within class classically damped systems. A index developed by and based upon modal ratios confirms that, Rayleigh systems,...
Summary According to Eurocode 8, the seismic design of flat‐bottom circular silos containing grain‐like material is based on a rough estimate inertial force imposed structure by ensiled content during an earthquake: 80% mass multiplied peak ground acceleration. A recent analytical consideration horizontal shear mobilised within earthquake proposed some authors has resulted in radically reduced this load suggesting that, practice, effective significantly less than that specified. This paper...
The seismic design of industrial flat-bottom ground-supported silos filled with granular material still presents several challenges to be addressed. They are related the main aspects which differentiate silo structures containing from other civil structural typologies: 1) relatively low structure mass as compared ensiled content mass; 2) nature material. Indeed, internal actions in members governed by complex dynamic interactions along interfaces between and wall or base, even interaction...
Historical monuments, by their own features and evolution over time, represent a unicum characterized large uncertainties. With the aim of preserving cultural heritage for future generations, assessment static conditions monuments is crucial point. In order to perform robust reliable evaluation structural behavior eventually forecast possible safety level, it fundamental importance carry out comprehensive study taking into account contributions coming from different fields. The this article...
Recent earthquakes have shown the key role of post-earthquake technical inspections aimed at assessing seismic safety and/or usability buildings and functionality infrastructural systems, in order to minimize impact losses on citizens as fast possible.
