Multiple support seismic excitation of the Evripos bridge based on free-field and on-structure recordings

The 395m long Evripos bridge in central Greece, connects the island of Evia to the mainland. An accelerometer array of 43 triaxial sensors has been monitoring both the free-field excitation and the response of the superstructure in a series of seismic events since 1994. This paper focuses on the characteristics of the spatially variable, earthquake ground motions recorded during two seismic events (1999 & 2013) and the corresponding bridge response. A model updating is performed to match the numerically predicted with the measured bridge response. Then, the nature of the recorded ground motions is studied and the incoherency patterns of the seismic waves are compared with empirical or semi-empirical models. It is observed that the loss of coherency at the site is isotropic. It is also documented, for the first time based on actual free-field and on-structure recordings, that the asynchronous excitation of a bridge excited higher modes of vibration while suppressing the oscillation on its fundamental frequency. The latter is in line with analytical predictions and is believed to be a key finding in understanding the nature of spatially variable earthquake ground motion and predicting its potential impact on the seismic response of bridges.

Building Wizard 2.0 release: A GUI for seismic analysis of buildings using OpenSees

Building Wizard is an interactive front-end software for the seismic analysis and assessment of buildings structures, that takes advantage of a sophisticated, Open-Source software for Earthquake Engineering Simulation (OpenSees) to provide through its graphical user’s interface: (a) conceptual assistance during the finite element analysis pre- and post-processing (b) finite element model development automations and (c) expert advice for modeling various building-specific issues that are key for the reliable prediction of structural response (such as shear wall connections, soil-structure interaction etc). Building Wizard improves the efficiency and credibility of the finite element modeling developed, particularly for the case of complex buildings structures and gives the designer more control in critical modeling decisions affecting the overall system response.

Reconnaissance report on the dual Cephalonia Earthquake

Two major earthquakes with Mw = 6.0 and Mw = 6.1 hit the Cephalonia Island of Greece on January 26th and February 3rd of 2014, respectively.The reconnaissance mission was unique in two ways: First, it brought together the local, highly qualified earthquake engineering community, with a US collaborative team of GEER, EERI, and ATC to form a 70-people multidisciplinary team. Second, the resiliency of building stock, geostructures, and communities that responded successfully to one of the strongest sequence of ground motions ever recorded in Europe provided the opportunity to focus on collecting data of successful performance in addition to failures - a new generation of reconnaissance.

The reconnaissance report (Version 1) is available at www.geerassociation.org/GEER_Post%20EQ%20Reports/Cephalonia_Greece_2014/index.html
with observations on: (i) seismological and recorded motions; (ii) geotechnical aspects; (iii) rigid blocks behavior; (iv) structural response; (v) infrastructure lifelines; (vi) nonstructural components response; and (v) economical and societal aspects.
