"This book features chapters based on selected presentations from the International Congress on Advanced Earthquake Resistance of Structures, AERS2016, held in Samsun, Turkey, from 24 to 28 October 2016.It covers the latest advances in three widely popular research areas in Earthquake Engineering: Performance-Based Seismic Design, Seismic Isolation Systems, and Structural Health Monitoring.
The book shows the vulnerability of high-rise and seismically isolated buildings to long periods of strong ground motions, and proposes new passive and semi-active structural seismic isolation systems to protect against such effects. These systems are validated through real-time hybrid tests on shaking tables.
Structural health monitoring systems provide rapid assessment of structural safety after an earthquake and allow preventive measures to be taken, such as shutting down the elevators and gas lines, before damage occurs. Using the vibration data from instrumented tall buildings, the book demonstrates that large, distant earthquakes and surface waves, which are not accounted for in most attenuation equations, can cause long-duration shaking and damage in tall buildings.
The overview of the current performance-based design methodologies includes discussions on the design of tall buildings and the reasons common prescriptive code provisions are not sufficient to address the requirements of tall-building design. In addition, the book explains the modelling and acceptance criteria associated with various performance-based design guidelines, and discusses issues such as selection and scaling of ground motion records, soil-foundation-structure interaction, and seismic instrumentation and peer review needs.The book is of interest to a wide range of professionals in earthquake engineering, including designers, researchers, and graduate students."

"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."

"This volume presents the first outcomes of the SERIES and its contribution towards performance-based earthquake engineering, i.e., to the most important development in earthquake engineering of the past three decades. The concept and the methodologies for performance-based earthquake engineering have now matured. However, they are based mainly on analytical/numerical research and large-scale seismic testing has entered the stage recently. "

"Dalam proses mendesain struktur geoteknik, perlu diperhatikan mengenai ketidakpastian parameter kuat geser pada tanah. Ketidakpastian tersebut dapat mempengaruhi stabilitas struktur dan menyebabkan keluarnya biaya berlebih akibat kegagalan yang terjadi. Pada penelitian ini, akan disajikan proses pemilihan struktur galian pada lingkungan perkotaan dengan memperhatikan ketidakpastian parameter tanah yang dihitung menggunakan metode probabilistik. Struktur galian yang akan dipertimbangkan adalah galian lereng terbuka dan galian dengan dinding penahan tipe sheet pile dan secant pile. Proses pemilihan struktur galian menggunakan analisis Expected Monetary Value dengan mempertimbangkan biaya pembebasan lahan, biaya konstruksi, biaya perbaikan akibat terjadi kegagalan, dan kehilangan pendapatan akibat terjadi kegagalan. Hasilnya menunjukkan bahwa dalam proses pengambilan keputusan sangat dipengaruhi oleh faktor biaya pembebasan lahan, diikuti dengan faktor biaya kehilangan pendapatan, biaya konstruksi dan biaya rekonstruksi.

In the process of designing geotechnical structures, it is important to consider the uncertainty of soil shear strength parameters. This uncertainty can influence the soil structure stability and resulting in unexpected expenses due to structural failure. This research will provide a decision making process to choose which type of slope excavation structure in urban areas by considering the uncertainty of soil parameters using probabilistic method. Slope excavation structures which will be considered are open-cut slopes, excavation with sheet pile and secant pile retaining wall. The decision making process will be calculated by using Expected Monetary Value analysis which considers land acquisition cost, construction cost, reconstruction cost caused by failure and revenue lost caused by failure. The result shows that the biggest cost which affected the decision is the land acquisition cost, followed by revenue lost cost, construction cost, and reconstruction cost."

"Geoteknik adalah salah satu cabang ilmu teknik sipil yang tertua di Dunia, yang terus berkembang bersamaan dengan tingkat peradaban manusia. Dalam prakteknya terdapat banyak faktor ketidakpastian, baik dari segi desain dan juga dengan material tanah itu sendiri yang mempunyai inherent variability yang besar dan data tanah yang terbatas akan membuat ahli geoteknik mengambil parameter tanah menjadi under estimated bahkan bisa menjadi over estimated. Oleh karena itu faktor keamanan FS digunakan dalam desain sebagai solusi untuk mengurangi resiko kegagalan desain, namun FS dapat menyesatkan karena biasanya dianjurkan atau digunakan tanpa refrensi khusus dan terlalu subjektif.
Salah satu pendekatan alternative adalah Reliability Based Design RBD, RBD merupakan metodologi desain yang mencoba merangkum dan memasukan faktor-faktor kunci dari ketidakpastian, sebab-akibat antara setiap variable dan kemungkinan-kemungkinan akibat resiko yang akan terjadi, sehingga hasilnya akan lebih mendekati kondisi sesungguhnya.
Pada penelitian ini penulis akan membahas mengenai analisis ketidakpastian terhadap penurunan pondasi tiang pancang berdasarkan data tanah hasil penyelidikan lapangan yang akan dikalibrasi dengan data hasil pengujian pembebanan statik aksial tekan pada beberapa proyek di Jakarta, diharapkan dengan menggunakan faktor-faktor kunci dari ketidakpastian yang merupakan tahap awal dari RBD akan menghasilkan desain yang lebih optimal dan ekonomis dengan tetap mempertahankan keamanan dari desain yang dihasilkan.Kata Kunci: Ketidakpastian, Inherent variability, Faktor keamanan, Reliability dan Penurunan tiang pancang.

Geotechnical engineering is one of the oldest majors of civil engineering in the World, which continues to grow along with the level of human civilization. In the practice there are many factors of uncertainty, both in terms of design and also with the soil material itself which has large inherent variability and limited soil data will make geotechnical experts take the parameters of the soil to be under estimated even be over estimated. Therefore the safety factor FS is used in the design as a solution to reduce the risk of design failure, but FS can be misleading as it is usually recommended or used without specific refrence and is very subjective.
One of the alternative approach is Reliability Based Design RBD , RBD is a design methodology that tries to summarize and incorporate the key factors of uncertainty, the couse and effect for ecery variable and possible consequences of the consequences that will occur, so the results will be more accurate.
In this study the authors will discuss about uncertainty analysis of pile settlement based on soil investigation data and the result will be calibrated with the data of static axial loading test based on some projects in Jakarta, it is expected by using the key factors of uncertainty which is the initial step of the RBD will make the result more optimal and economical design while maintaining the safety of design.Key Word Uncertainty, Inherent variability, Safety Factor, Reliability and Pile Settlement.
