In this paper, the seismic responses control characteristics of Mega-structure, Mega-sub Controlled Structure System (MSCSS) without dampers and MSCSS inserted friction dampers are investigated respectively under rare earthquake by using the elastic-plastic time history analysis method. The distribution of plastic hinges and different control efficiency of these structures under rare earthquake...

In an automotive system, the vehicle suspension usually contributes to the vehicle's handling and braking for good active safety and driving pleasure and keeps the vehicle occupants comfortable and reasonably well isolated from road noise, bumps and vibrations. The design of vehicle suspension systems is an active research field in automotive industry (Du and Zhang, 2007; Guglielmino, et al., 2...

Semiactive control systems that offer the reliability of passive control systems as well as the versatility and adaptability of active control systems have received significant attention for structural vibration control (Jung et al., 2004). Magnetorheological (MR) fluid dampers have emerged as such a class of semiactive damping devices. By activating the MR fluid contained in the device through...

Periodic metafoundations have proven to inherit valuable properties from wave propagating in phononic periodic structures the very low-frequency regime. Therefore, finite locally resonant (LRMs) represent a novel type of seismic isolation for ultralow-frequency applications. In this context, it is still unknown impact that massive resonators with varying frequencies or devices hysteretic behavi...

Currently in the city of Lima there is a limited number high-rise buildings. Therefore, not much literature on this type building Peru. Peruvian codes focus medium and low-rise For reason, studies are required to analyze design these tall buildings more appropriately according reality country. In article, pushover modal analysis 6 types 35-Story reinforced concrete will be developed. Three mode...

The primary purpose of this chapter is to present an approach for developing nonparametric models for magneto-rheological (MR) dampers. Upon describing the approach adopted here, a non-parametric model for a commercial magneto-rheological damper is developed, and is compared with a parametric model from an earlier study. The results show that the proposed non-parametric model can more effective...

Modeling of magneto-rheological dampers to be used in semi-active control of civil engineering structures is addressed. The behavior of this kind of dampers is modeled through a first order Lugre dynamic friction model whose structure is analytically simpler than other dynamic friction models used in the literature. With this structure real-time parametric identification of the magneto-rheologi...

This paper presents the evaluation of seismic performance and cost-effectiveness of a multiple slim-type damper system developed for the vibration control of earthquake excited buildings. The multiple slim-type damper (MSD) that consists of several small slim-type dampers and linkage units can control damping capacity easily by changing the number of small dampers. To evaluate the performance o...

——Magnetorheological (MR) dampers are devices that can be used for vibration reduction in structures. However, to use these devices in an effective way, a precise modeling is required. In this sense, in this paper we consider a modied parameter identication method of large-scale magnetorheological dampers which are represented using the normalized BoucWen model. The main benet of the propose...
