This book gathers 23 papers by top experts from 11 countries, presented at the 3rd Houston International Forum: Concrete Structures in Earthquake. Designing infrastructures to resist earthquakes has always been the focus and mission of scientists and engineers located in tectonically active regions, especially around the Pacific Rim of Fire including China, Japan, and the USA. The pace of research and innovation has accelerated in the past three decades, reflecting the need to mitigate the risk of severe damage to interconnected infrastructures, and to facilitate the incorporation of high-speed computers and the internet. The respective papers focus on the design and analysis of concrete structures subjected to earthquakes, advance the state of knowledge in disaster mitigation, and address the safety of infrastructures in general.

This book focuses on the seismic design of Structures, Piping Systems and Components (SSC). It explains the basic mechanisms of earthquakes, generation of design basis ground motion, and fundamentals of structural dynamics; further, it delves into geotechnical aspects related to the earthquake design, analysis of multi degree-of-freedom systems, and seismic design of RC structures and steel structures. The book discusses the design of components and piping systems located at the ground level as well as at different floor levels of the structure. It also covers anchorage design of component and piping system, and provides an introduction to retrofitting, seismic response control including seismic base isolation, and testing of SSCs. The book is written in an easy-to-understand way, with review questions, case studies and detailed examples on each topic. This educational approach makes the book useful in both classrooms and professional training courses for students, researchers, and professionals alike.

Abstrak :
Indonesia merupakan wilayah yang memiliki titik gempa paling banyak karena berada di pertemuan empat lempeng tektonik dunia. Belakangan ini semakin sering terjadi gempa. Akibatnya pemerintah berencana mengganti peraturan gempa SNI 03-1726-2002 dengan RSNI 03-1726-201x. Selain itu, perencanaan bangunan yang selama ini berdasarkan kekuatan struktur bangunan, mulai beralih menjadi berdasarkan level kinerja, dengan metode analisis pushover statik nonlinear. Objek penelitian ini adalah sistem struktur penahan gaya lateral berupa rangka bresing eksentris. Sistem struktur dimodelkan dalam bangunan tiga dimensi dengan menggunakan program ETABS ver. 9.7. Terdapat variasi tinggi bangunan dan model pemasangan bresing untuk dapat membandingkan perilaku struktur dan kinerja bangunan. Hasil yang didapat adalah pemasangan bresing model B memiliki perilaku struktur yang lebih baik daripada model A. Bangunan rendah (6 lantai) dan bangunan tinggi (12 dan 18 lantai) sama-sam mengalami kelelehan pertama saat kondisi plastis. Namun, model keruntuhan pada bangunan rendah lebih baik daripada bangunan tinggi. Hasil penelitian ini hanya berlaku untuk bangunan struktur baja yang berada di Jakarta pada tanah lunak.

Being at the meeting point of four tectonic plates, Indonesia has the most earthquake-point in the world. Lately, more and more earthquakes frequently happen. As a result, the government plans to replace the earthquake regulations of SNI 03-1726-2002 with RSNI 03-1726-201x. In addition, design of the building which has been based on structural strength, began to switch to based on level of performance, with nonlinear static pushover analysis method. Object of this study is structural system of retaining the lateral force with eccentrically braced frames. The structure is modeled in three-dimensional buildings using ETABS ver.9.7. There are variations in height of the building and in the model of the bracing to compare the structural behavior and performance of the buildings. The results obtained are bracing with model B has a better structural behavior than the model A. Low building (6 floors) and tall building (12 and 18 floors) have first yielding in the same conditions, plastic conditions. Eventhough the collapse process of the low building models are better than tall buildings. The results of this study apply only to building steel structure that was in Jakarta on soft ground.
