Rectangular and Cylindrical TLDs with Rotatable Baffles to Improve Seismic Behavior of Structures, a Numerical Study
One of structural passive control methods is to use Tuned Liquid Damper (TLD). However, because of the nature of the TLD, only one tuning frequency can be created when the water is sloshing. To fix this problem, some installed rotatable baffles can be embedded inside TLD called Variably Baffled TLD (VBTLD) where by changing the angle of the baffles a tuning frequency range is created. This gives ...
متن کاملComparative 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 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...
