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.

CALL FOR ABSTRACTS
The Scientific Committee invites all participants wishing to contribute to the scientific program to submit an abstract for oral presentation. Abstracts must be submitted by the deadline, January 10, 2014, to the following e-mail address:ibsbi2014@ntua.gr . Abstracts received after this date will not be considered.
Selected papers of high quality will be considered for publication in an extended form in the new International Journal IJBE after invitation ( http://www.ijbe.net/ ).
The primary objective of the NEES@Illinois facility is to create a physical-analytical simulation environment whereby multi-axial, full-scale structure-foundation-soil systems can be subjected to complex loading and boundary conditions representing earthquake ground motion. Actions and responses are captured by state-of-the-art instrumentation and are processed and visualized using software developed by the site.
The major physical components of the facility are the reaction structure and the loading and boundary condition boxes, or LBCBs. Each LBCB is a self-reacting assembly of actuators, swivel joints, and control software capable of imposing any combination of six actions (forces and moments) and six deformations (displacements and rotations) on specimens connected to the loading platforms of the LBCBs. The site has three (3) large LBCBs, which can be used separately or in combination. When used together the LBCBs can be controlled independently, or they can be controlled to act as a single LBCB with increased load capacity. One of the key attributes of the MUST-SIM facility is that the LBCBs may be reconfigured to accommodate a vast array of testing needs. Examples of past tests and specifications of the test equipment will be presented during the webinar.
In addition to the full-scale facility, the NEES@Illinois site has a fully-operational, 1/5th-scale version of the MUST-SIM laboratory. This facility provides a realistic pre-test environment and serves as an education and outreach facility, but has also proven to be a worthy research facility in its own right.
Beyond the hardware aspects of the laboratory, NEES@Illinois has also developed the control systems and data acquisition systems used in the MUST-SIM. These systems will be covered in detail.
Hybrid simulation offers the most realistic testing to mimic actual system responses and NEES@Illinois is at the forefront of this area of research. 3-D hybrid simulation using UI-SimCor, a simulation coordinator developed at NEES@Illinois, will also be discussed.

By NISEE
Hospital reconstruction and seismic strengthening provided continuous demand for construction design and engineering services in recent years. (See NISEE, Dec 9, 2011) In California, compliance with mandatory seismic performance objectives for critical health care facilities is largely supervised through the California Office of Statewide Planning and Development (OSPD). A hospital’s ability to function adequately after a large earthquake is dependent on the building’s structural components (a building’s primary load carrying system of foundation, columns, beams, floors, walls and roof), non-structural components (building elements such as ceilings, partitions, pipes, mechanical and electrical, that are not part of the structural load-bearing system), occupants (staff and patients) and contents (equipment, supplies, furnishings, etc.) remaining largely undamaged. Hospital serviceability after natural disaster relies on robust interconnectedness of lifeline systems (water, power, transportation, etc.) that support hospital services. The constitution of structural, non-structural and contents may provide unique seismic strengthening challenges for hospitals.
For seismic strengthening of modern hospital buildings, reliable site-specific loss estimation techniques (e.g.: Blume-157) can account for structural and non-structural damage. Engineering building codes (e.g.:ICBO, FEMA, California Building Codes), applied research programs (e.g.: ATC-58, MCEER, Japan E-Defense) and sophisticated testing methodologies to analyze and strengthen structural and many non-structural systems to resist moderate to strong earthquake shaking or geotechnical damage are reasonably advanced. Video of recent shake-table testing at the University of California, San Diego (‘Building it Better: Earthquake-Resilient Hospitals for the Future’) confirms some ability to achieve both structural and non-structural hospital resilience after credible earthquakes in California.
Ντοκιμαντέρ του ΣΚΑΪ καταγράφει μέσα από συγκλονιστικές εικόνες τον σεισμό των 9 Ρίχτερ, το τσουνάμι και την πυρηνική καταστροφή στην Φουκουσίμα της Ιαπωνίας. Αυτόπτες μάρτυρες αλλά και επιστήμονες που βίωσαν και μελετούν αντίστοιχα αυτό το σεισμό και τις συνέπειες που προκλήθηκαν στην Ιαπωνία μιλούν στην κάμερα. Τα 9 Ρίχτερ που χτύπησαν την Ιαπωνία την Παρασκευή 11 Μαρτίου 2011 αποτέλεσαν τον πέμπτο μεγαλύτερο σεισμό που έχει καταγραφεί στον κόσμο από το 1900. Το τσουνάμι που ακολούθησε έφερε και τις εφιαλτικές συνέπειες των 10.000 και πλέον νεκρών αλλά και χιλιάδων αγνοουμένων. Ολόκληρες πόλεις χάθηκαν και τίποτα δεν είναι πια ίδιο για τους Ιάπωνες αλλά και ολόκληρο τον κόσμο μετά την καταστροφή που υπέστη το πυρηνικό εργοστάσιο της Φουκουσίμα
