In order to solve the shortcomings of traditional TLDs (tuned liquid dampers), such as their narrow frequency bands and occupation large amounts space, based on deep-water theory, a new type TLD incorporating Karmen vortex street theory is proposed named KV-TLD. A shaking table experimental test conducted fully analyze its vibration damping characteristics effectiveness in terms control confirm...

Tuned liquid dampers (TLDs) have been broadly applied to suppress structural vibrations. In the present study, a novel vibration mitigation device consisting of non-Newtonian fluids coupled with an elastic baffle is proposed. The fluid-structure interaction studied numerically. To optimize system, different fluids, including Bingham fluid, Pseudoplastic and Dilatant fluid are used as damping su...

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 this paper, a state-of-the-art literature review is presented emphasising on the development of control variants for mass damper schemes building-like structures. Additionally, systematic conducted addressing three relevant questions: What type preferable by associated industry? How are dampers distributed around world? Is industry following research? Through review, updated lists implementa...

Introduction. The historic cable-stayed suspension bridge of the city Deir ez-Zor in Syria, which is an architectural monument, described. history its creation at beginning twentieth century and destruction during hostilities 2013 given. importance this for country as a whole indicated, was reason choice object research. Aim. study intended to contribute restoration (or) subsequent seismic stre...

In this paper, the development of non-linear building isolation systems is overviewed. The study summarizes commonly used linear in two categories, which are base and inter-storey systems. Typical isolators including Lead-Rubber Bearings Friction Pendulum viscous damper Tuned Mass Damper reviewed. analysis design also reported. After that, introduced from aspects based on their dynamic characte...

abstract: appealing to the principle of vertical residence and stemming the horizontal expansion of the city, the tehran milad tower is being built on 35000 sm3 site with the total area of 220000 sm3. with a height of over 170m, this 56-story concrete building is in the final stages of construction and would be the highest residential building of iran. since tehran is located in a high-risk ear...
