Indonesia merupakan negara dengan tingkat bencana gema bumi yang tinggi. Banyak kerugian yang terjadi akibat gempa bumi, seperti kerugian materi dan korban jiwa. Terdapat beberapa metode untuk mengurangi dampak kerusakan yang ditimbulkan oleh gempa bumi. Pada penelitian ini dikaji tentang respon struktur dengan menggunakan base isolation. Untuk mengetahui respon struktur suatu bangunan digunakan persamaan diferensial dari persamaan gerak. Program yang digunakan adalah dengan menggunakan bahasa pemrograman Julia. Perbandingan hasil dari bangunan yang diberi base isolation menunjukan bahwa frekuensi dan kecepatan yang dialami struktur berkurang dibandingkan yang tidak dipasang base isolation. Perubahan tersebut dapat mengurangi dampak yang ditimbulkan akibat gempa bumi yang terjadi. ......Indonesia is a country with a high level of earthquake disaster. Many losses occur due to earthquakes, such as material losses and fatalities. There are several methods to reduce the impact of damage caused by earthquakes. In this study, the structure response is based on base isolation. To find out the structural response of a building, a differential equation of motion equation is used. The program used is by using Julias programming language. Comparison of results from buildings given base isolation shows that the frequency and speed experienced by the structure is reduced compared to those without base isolation. These changes can reduce the impact caused by the earthquake that occurred.

This book reports on a comprehensive analytical, experimental and numerical study on the flexural response of post-tensioned masonry walls under in-plane loads. It explores an important mechanism in this new generation of structural walls, called “Self-centering”. This mechanism can reduce residual drifts and structural damage during earthquake ground motion, and is particularly favorable for structures which are designed for immediate occupancy performance levels. The book reports on the development and verification of a finite element model of post-tensioned masonry walls. It describes a detailed parametric study to predict the strength of post-tensioned masonry walls. New design methodologies and expressions are developed to predict the flexural strength and force-displacement response of post-tensioned masonry. Experimental study is carried out to better understand the behavior of post-tensioned masonry walls and also to evaluate the accuracy of the proposed design procedure and expressions. The book also includes an introduction to current research on unbounded post-tensioned masonry walls, together with an extensive analysis of previously published test results.
