Comparative Performance Study of Tuned Liquid Column Ball Damper for Excessive Liquid Displacement on Response Reduction of Structure
The tuned liquid column damper (TLCD) having a uniform cross-sectional tube of U-shaped, occupied with liquid is used as a vibrational response mitigation device. The tuned liquid column ball damper (TLCBD) is a modified TLCD, where, an immovable orifice, positioned at the middle part of the horizontal portion, is replaced by a metal ball. Different studies on the unconstrained optimization per...
متن کاملبررسی اثرات استفاده از میراگر مایع هماهنگ شده (tuned liquid damper-tld)در کاهش پاسخ لرزه ای سازه های چند درجه آزادی
از اوائل دهه اخیر، سیستم کنترل غیرفعال جدید در زمینه کاهش ارتعاشات سازه ها مطرح شده که میراگر مایع هماهنگ شده (tuned liquid damper) یا اختصارا tld نامیده می شود. اساس کار آن بر مبنای استهلاک انرژی وارده به سازه (ناشی ازدیاد، زلزله و...) توسط تلاطم مایع کم عمقی در درون یک یا چند مخزن است که در بالای سازه نصب می گردد. عمق ولزجت مایع و همچنین ابعاد و تعداد تانکها به منظور رسیدن به درصد است...
15 صفحه اولReal time tuned mass damper simulation system
The major concern in the construction industry in constructing tall structures is vibration due to wind and earthquake. Tuned mass dampers are an effective and practical ways to reduce the effect of vibration in structures. This thesis presents a tool, which simulates the effect of tuned mass dampers on the structure. This tool has been proposed to form a part of the website, moment.mit.edu. Ja...
متن کاملExperimental Study on Using Uniform Tuned Liquid Column Damper for Structural Control of Buildings Resting on Loose Soil
In this study, through series of shaking table tests and statistical analysis, the efficiency of Uniform Tuned Liquid Column Damper (UTLCD) in structures resting on loose soils, considering soil-structure interaction was investigated. The soil beneath the structure is loose sandy soil. The Laminar Shear Box (LSB) as a soil container was adopted and the scaled form of the prototype structure nam...
متن کاملClosed Form Optimal Solution of a Tuned Liquid Column Damper Responding to Earthquake
In this paper the vibration behaviors of a structure equipped with a tuned liquid column damper (TLCD) under a harmonic type of earthquake loading are studied. However, due to inherent nonlinear liquid damping, it is no doubt that a great deal of computational effort is required to search the optimum parameters of the TLCD, numerically. Therefore by linearization the equation of motion of the s...
