EERI new database of RC buildings damaged by earthquakes

Συντάχθηκε από nisida στις . Καταχωρήθηκε στο αστοχίες κατασκευών, εφαρμογές πληροφορικής (ICT).

The new EERI database is an excellent and very educational colllection of seismically induced damage of reinforced concrete buildings. It contains over 50 case studies on concrete buildings damaged in over 20 earthquakes. Each case study provides detailed information about the building and photographs of damage. The information presented has been extracted from references and discussions with mentors. The database is presented as a baseline for further research and should not be construed as definitive analysis. Images in the database are taken from references, online reports, EERI photo collections, and individual mentors. For more information about this database, visit http://db.concretecoalition.org/

A similar initiative for Greek earthquakes is available here: http://asptetk.civil.auth.gr/Pages/DataForm.aspx

Civil Engineering Toolbox for iPad

Συντάχθηκε από nisida στις . Καταχωρήθηκε στο app, Civil engineer, civil engineering, Engineering, Global Positioning System, GPS, iOS, ipad, mobile, Reinforced concrete, software, statics, Structural engineer, Toolbox.

Civil Engineering Toolbox is a revolutionary way to perform simple and some not-so-simple, structural engineering calculations using iPad. It is not about solving complex math but rather about understanding and conceptually decoupling the fundamental steps of structural engineering: (a) define the structural system, (b) define the loading patterns acting on the structure, (c) select material properties from a database, (d) select sections from a database, (e) check the developed stresses, the displacements and the associated cost. If acceptable, that’s fine; if not, the user needs to think carefully which one of (a)-(d) need to be modified to get the optimum balance between safety factor and cost. In case it is needed, a photo can be captured on site and the entire calculation package can be sent to the office computer by e-mail together with the exact GPS location of the site.

With Civil Engineering Toolbox, the engineer can perform the following tasks:
-Design a reinforced concrete beam in flexure [required reinforcement and associated cost]
-Solve a simply supported slab [for various supports and loads, according to Czerny method]
-Solve a straight, simply supported beam [for various supports and loads]
-Solve a one bay frame [for various supports and loads]
-Solve a continuous beam and plot deflections, bending moments and shear forces [for various number of spans, supports and uniform/non-uniform loads]
-Manage the Material Properties Library [reinforced concrete and steel materials]
-Manage the Structural Section Library [Rectangular R/C sections & IPE, HEA, HEB, IPN steel sections]
-Report generation and e-mail export (inclusive of results, photo and GPS location]

NEES@Illinois MUST-SIM Facility’s Physical Test & Hybrid Simulation

Συντάχθηκε από nisida στις . Καταχωρήθηκε στο Earthquake engineering, Illinois, Simulation, αντισεισμική μηχανική, εφαρμογές πληροφορικής (ICT), πειραματική μηχανική.

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.

Investing in educational technology in the times of the Greek financial recession

Sextos, A.G. (2013) “A Paperless Course on Structural Engineering Programming: investing in educational technology in the times of the Greek financial recession”, European Journal of Engineering Education. 

This paper presents the structure of an undergraduate course entitled ‘programming techniques and the use of specialised software in structural engineering’ which is offered to the fifth (final) year students of the Civil Engineering Department of Aristotle University Thessaloniki in Greece. The aim of this course is to demonstrate the use of new information technologies in the field of structural engineering and to teach modern programming and finite element simulation techniques that the students can in turn apply in both research and everyday design of structures. The course also focuses on the physical interpretation of structural engineering problems, in a way that the students become familiar with the concept of computational tools without losing perspective from the engineering problem studied. For this purpose, a wide variety of structural engineering problems are studied in class, involving structural statics, dynamics, earthquake engineering, design of reinforced concrete and steel structures as well as data and information management. The main novelty of the course is that it is taught and examined solely in the computer laboratory ensuring that each student can accomplish the prescribed ‘hands-on’ training on a dedicated computer, strictly on a 1:1 student over hardware ratio. Significant effort has also been put so that modern educational techniques and tools are utilised to offer the course in an essentially paperless mode. This involves electronic educational material, video tutorials, student information in real time and exams given and assessed electronically through an ad hoc developed, personalised, electronic system. The positive feedback received from the students reveals that the concept of a paperless course is not only applicable in real academic conditions but is also a promising approach that significantly increases student productivity and engagement. The question, however, is whether such an investment in educational technology is indeed timely during economic recession, where the academic priorities are rapidly changing. In the light of this unfavourable and unstable financial environment, a critical overview of the strengths, the weaknesses, the opportunities and the threats of this effort is presented herein, hopefully contributing to the discussion on the future of higher education in the time of crisis.
