Abstract

Tuned Liquid Damper (TLD) merupakan peredam pasif yang mampu meredam getaran struktur melalui mekanisme anti-phase sloshing cairan yang telah diatur. TLD bisa sangat efektif meredam getaran pada struktur jika parameternya mampu direncanakan secara tepat. Parameter yang menentukan efektifitas TLD adalah struktur yang dipakai, rasio massa liquid dengan massa struktur, rasio frekuensi liquid dengan frekuensi struktur, dan pengaruh beban eskitasi. Pengujian parameter TLD secara eksperimen untuk mendapatkan parameter optimum telah dilakukan pada percobaan terdahulu dengan membuat struktur sederhana yang dapat diuji di laboratorium. Namun, pengaruh parameter TLD saat diaplikasikan pada bangunan gedung belum diketahui. Studi ini meninjau pengaruh parameter TLD jika diaplikasikan pada beberapa jenis bangunan gedung dengan tinggi lantai yang berbeda dan dengan beragam variasi parameter yang berpengaruh. Untuk menguji TLD pada bangunan gedung dibuat model mekanik TLD yang sesuai dengan kondisi sebenarnya, set eksperimen terdahulu dimodelkan kembali menggunakan SAP2000 dan hasilnya diverifikasi sesuai hasil eksperimen. 3 gedung dengan struktur baja dimodelkan dengan jumlah lantai 3,6 dan 15 lantai. Tiap model gedung tersebut diuji dengan variasi parameter TLD yakni rasio massa 1-4% dan rasio frekuensi 0.8-1.1. Selain itu, pengaruh beban dinamik berupa rasio frekuensi eksitasi 0.8-1.3 dan karakteristik ground motion juga diselidiki. Dari hasil pengujian didapatkan gedung dengan tinggi lantai paling tinggi dan rasio massa paling besar serta rasio frekuensi 0.9 memberikan respon yang paling. Selain itu, TLD didapatkan akan lebih efektif pada Far Fault Earthquake dan jika dikenai beban eksitasi yang mendekati frekuensi resonansi.

A Tuned Liquid Damper (TLD) is a passive damper that is capable of reducing the dynamic response of a structure through an anti-phase sloshing fluid mechanism that has been settled. TLD can be very effective in a structure if its parameters are designed properly. The parameters that determine the effectiveness of the TLD are the structure used, the mass ratio, the frequency ratio, and the effect of the excitation load. Experimental testing of TLD parameters to obtain optimum parameters has been carried out in previous experiments by making simple structures that can be tested in the laboratory. However, the influence of TLD parameters when applied to buildings remains unknown. This study examines the effect of TLD parameters when applied to several types of buildings with different floor heights and with variations of the influential parameters. To test the TLD in buildings, a mechanical TLD model was created based on actual conditions; the previous experimental set was remodeled using SAP2000; and the results were validated using experimental data. Three steel-framed buildings are modeled with the numbers of floors 3, 6, and 15 respectively. Each building model was evaluated with varying TLD parameters, including a mass ratio of 1% to 4% and a frequency ratio of 0.8% to 1.1%. In addition, the influence of dynamic loads in the form of an excitation frequency ratio between 0.8 and 1.3 and the characteristics of ground motion were investigated. Based on the test results, it was found that the structure with the highest floor height and mass ratio, as well as a frequency ratio of 0.9, provided the best response. In addition, the TLD has been discovered to be more effective for far-fault earthquakes and when subjected to an excitation load close to its resonant frequency.
