7th International Conference on Experimental Vibration Analysis for Civil Engineering Structures

July 12-14, 2017 - San Diego, California, United States

2

WELCOME MESSAGE

Research, development, and applications in experimental vibration analysis of civil engineering structures are being fed by the continuous progress in the fields of sensor and testing technologies, instrumentation, data acquisition systems, computer technology, and computational modeling and simulation of large and complex civil infrastructure systems. The objectives and challenges are to understand the behavior and state of health of structural, geo-structural, and soil-foundation-structural systems as well as predicting their remaining useful life using vibration data collected from these systems when subjected to operational and extreme loads. Advanced data analysis (e.g., system and damage identification) methods are required to extract the needed information from the data and to gain from the information the knowledge required to support decision making related to maintenance and inspection, retrofit, upgrade, and rehabilitation of these systems as well as in case of emergency response. These data analysis methods are developed using numerically simulated structural response data, experimental data from small-scale physical structural models, experimental data from large- or full-scale physical structural specimens tested under laboratory conditions, or field data collected from civil structures under in-situ conditions.

EVACES, the International Conference on Experimental Vibration Analysis for Civil Engineering Structures is a premier venue where recent progress in the field are presented and discussed by experts from all over the world. After the first six successful editions of EVACES which took place in Bordeaux, France (2005), Porto, Portugal (2007), Wroclaw, Poland (2009), Varenna, Italy (2011), Ouro Preto, Brazil (2013), and Dübendorf, Switzerland (2015), EVACES 2017 was organized by the University of California at San Diego, and held on the main campus of the University during July 12-14, 2017.

The papers presented at EVACES 2017 are subdivided into the following sub-areas: (1) keynote papers, (2) damage identification and structural health monitoring, (3) testing, sensing and modeling, (3) vibration isolation and control, (4) system and model identification, and (5) coupled dynamical systems (including human-structure, vehicle-structure, and soil-structure interaction). These papers are published as a set of two books (e-books and hard copies) in the Lecture Notes in Civil Engineering (LNCE) Series of Springer.

The Southern California city of San Diego and its surroundings feature one of the most attractive locations in North America in terms of its geography, climate, natural beauty and cultural diversity, that the conference attendees are encouraged to explore (before and/or after the conference).

We express our sincere thanks to the members of the Organizing Committee, the members of the Scientific Committee and, in particular, all the authors and participants for their essential and valuable contributions.

Paris and San Diego, May 2017 Christian Cremona and Joel P. Conte

TOUR OF THE NHERI@UC SAN DIEGO LARGE HIGH-PERFORMANCE OUTDOOR SHAKE TABLE FACILITY

UC San Diego Large High Performance Outdoor Shake Table (LHPOST) was built under the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) program of the U.S. National Science Foundation (NSF) in response to the urgent need in the U.S. for a large shake-table facility. It is the world’s largest outdoor shake table and second largest overall with the largest being the E-Defense table in Japan. The LHPOST is part of the Englekirk Structural Engineering Center (ESEC) of UC San Diego which is located approximately 16 km east of the UC San Diego main campus at Camp Elliot Field Station. ESEC is an outdoor large-scale structural laboratory complex that comprises (i) the LHPOST, (ii) a blast and impact simulator, which does not involve explosives and the subsequent fireball, used to replicate the effects of blasts on structural components, (iii) a soil-structure-interaction facility consisting of two refillable soil pits separated by a strong reaction wall, and (iv) a full-scale railroad track built to investigate ultrasonic guided wave rail defect detection techniques. The LHPOST is an NSF Natural Hazards Engineering Research Infrastructure (NHERI) Experimental Facility to support research in structural and geotechnical earthquake engineering.
