Abstract

Abstrak. Penelitian ini membahas studi teori dan eksperimental mengenai kontrol pasif getaran pada struktur yang mengalami beban eksitasi gempa dengan menggunakan teknik isolasi yang dilakukan pada dasar struktur bangunan. Pada penelitian ini diusulkan penggunaan sistem isolasi dasar dengan menggunakan bantalan karet yang diletakkan di antara kolom pada lantai dasar dengan pondasi yang diharapkan mampu memperkecil perpindahan horisontal struktur bangunan. Model eksperimental yang digunakan adalah model portal baja dua tingkat dengan isolator bantalan karet pada tumpuannya dan diberi beban eksitasi dinamik dengan menggunakan meja getar. Hasil studi teori dan eksperimental untuk berbagai beban dinamik seperti percepatan horisontal gempa El Centro N-S menunjukkan penggunaan isolator pada dasar struktur bangunan memberikan hasil yang memuaskan dalam hal pengurangan tingkat getaran sehingga dapat meningkatkan kualitas keamanan dan kenyamanan struktur. Selain itu penggunaan isolator dasar pada struktur bangunan sangat menguntungkan karena pelaksanaannya yang relatif sederhana.Abstract. This study presents a theoretical and experimental study on passive vibration control for structures which are subjected to earthquake excitations using isolation technique which is implemented on the base of the building structure. The base isolation system, made of rubber pads, was proposed in this study to reduce the relative horizontal displacement of the structure. The experimental model for the study is a two-storey steel frame with rubber pads installed on its base. The dynamic excitations were given to the structure through a small shaking table. The theoretical and experimental studies for various dynamic loads, such as sinusoidal acceleration and simulation of El Centro NS earthquake acceleration, show that the use of the base isolator on the structure gives satisfactory results. The base isolation system reduces significantly the vibration level and improves the quality of safety and comfort of the structure. In addition, the use of the base isolator on the structure is very attractive because its implementation is relatively simple.

Abstract

This paper presents a theoretical and experimental study on active control structure excited by seismic loads using artificial neural network Artificial neural network is used to calculate the control force based on acceleration of the structure which is obtained by accelerometer measurement. The control mechanism is implemented on the structure using active stiflness and mass based on continuous vibration measurement. The reability of the active control system with artificial neural network has been tested experimentally using a reduced model of two=storey steel flame excited by base acceleration through a small shaking table. The experimental study shows that the artificial neural network control method gives satisfactory results for many types of base excitation such as random and El-Centro N-S earthquake accelerations. The neuro control algorithm is simple and reduces consideranbly computational time.

Abstract

Fenomena loncatan yang terdapat pada suatu sistem dinamik non-linier deterministik, telah lama dlkenal dengan baik. Tetapi pada sistem non-linier acak, fenomena ini sangat kurang dikenal. Secara alami sebagian besar strulkrur mengalami gaya-gaya luar yang sifatnya acak dan penyelesaian stokastik dari suatu sistem non-linier telah menarik perhatian banyak peneliti pada akhir-akhir ini. Pada tulisan ini akan diperlihatkan bahwa fenomena loncatan dapat dihasilkan dan suatu system non-linier yang mengalami gaya eksitasi luar acak. Masalah akan diselesaikan dengan menggunakan persamaan diferensial stokastik Ito, dan persamaan momen yang tak terbatas akan dibatasi dengan menggunakan bantuan metode Gauss tertutup.

Abstract

In recent years, the development and implementation of artificial intelligence (AI) have attracted tremendous attention. The implementation of active control systems for building structures can be improved by using an AI controller. Non-AI controllers such as the Linear Quadratic Regulator (LQR) controller require full state variables of the structure to be measured, which is rarely feasible. To address this problem, two AI models, namely, artificial neural network (ANN) and fuzzy logic (FL), have been tried as AI-based controller in various studies. In the present study, both AI models were investigated to see their practicality and effectiveness. The AI models were implemented to control an active mass damper (AMD) in a three-story prototype-sized building. The simulation results from the structure with an LQR controller were used as benchmark and training data for the AI models. The results of the study demonstrated that although both AI models could reduce the structure responses, ANN was more practical and effective compared to FL as an AI-based controller for the given structure. Furthermore, the effectiveness of an ANN-based AMD was also shown by the experimental results.
