CRUPE is testing multiple floor housing models at the Bogazici (Bosphorus) University Structural Mechanics Laboratory in Istanbul, Turkey which is one of the leading testing and engineering laboratories for testing structural models for seismic events in the world. The first stage of the testing comprises forced and ambient vibration tests and static loading of the CRUPEFrame steel structures. This testing is based in part on the data provided by the Xian University of Architecture and Engineering in China and the DICTUC School of Engineering at the Catholica University of Santiago de Chile where CRUPE has already completed many seismic and other material testing.
In the next stage CRUPE materials are sprayed on the structures with different configurations and the buildings are re-tested both dynamically and statically. In the final stages 3 dimensional dynamic characteristics of newly built CRUPE buildings are obtained and the limits of the structures will be observed allowing the contribution of CRUPE materials to the lateral load bearing resistance of the light steel structures to be analysed and formulated.
This data allows engineers and architects to dynamically design structures for better resistance to earthquakes and importantly optimise steel usage within the buildings given the structural performance of the CRUPE wall and ceiling materials. This is to our knowledge the first time dynamic modelling has been produced anywhere in the world where (semi) structural cladding material completely enveloping steel framework is used to enable dynamic mapping of the seismic energy disbursement.
Critically, it is the first time ever that a computerised model (CRUPECAD) will be able to dynamically calculate and optimise steel usage in the design phase based on these tests and data meaning that steel usage can be optimised within the building saving materials and cost. This is another world’s first for CRUPE and because of the implications of this testing and modelling on the construction of new built buildings in seismic areas the Government in Turkey have invited Asst. Prof. Dr. Serdar Soyoz who is coordinating the CRUPE project to join the committee that is preparing the new Seismic Code for Light Steel Structures in Turkey and have confirmed that the CRUPE test results will be used as the data in preparation of that Code.
Given that CRUPE will effectively become an integral part of the new coding requirements for steel structures in Turkey various large construction companies have already visited the University site and have confirmed they would like to start construction projects with CRUPE as soon as the testing and coding is completed later this year. Turkey is one of the most important construction markets in Europe (and Asia) and with the support of the University in Istanbul (who have already identified a number of masters thesis and likely at least one doctoral thesis working on CRUPE) and the National Government CRUPE will enter the Turkish market later this year as a key element for affordable, seismic resistant housing in compliance with the new coding requirements.
This has wide-reaching implications not only in Turkey but in all countries now seeking affordable, efficient and secure homes for fast track construction in seismic areas. CRUPE is starting the supply of materials for the first 6 homes (270m2) in Ankara for a private cooperative who is intending to build hundreds more homes following this first demo project and these early projects will help demonstrate the importance of the CRUPE system in markets like Turkey.
