Experimental identification of the six DOF C.G.S., Algeria, shaking table system
Airouche, Abdelhalim,Bechtoula, Hakim,Aknouche, Hassan,Thoen, Bradford K.,Benouar, Djillali Techno-Press 2014 Smart Structures and Systems, An International Jou Vol.13 No.1
Servohydraulic shaking tables are being increasingly used in the field of earthquake engineering. They play a critical role in the advancement of the research state and remain one of the valuable tools for seismic testing. Recently, the National Earthquake Engineering Research Center, CGS, has acquired a 6.1m x 6.1 m shaking table system which has a six degree-of-freedom testing capability. The maximum specimen mass that can be tested on the shaking table is 60 t. This facility is designed specially for testing a complete civil engineering structures, substructures and structural elements up to collapse or ultimate limit states. It can also be used for qualification testing of industrial equipments. The current paper presents the main findings of the experimental shake-down characterization testing of the CGS shaking table. The test program carried out in this study included random white noise and harmonic tests. These tests were performed along each of the six degrees of freedom, three translations and three rotations. This investigation provides fundamental parameters that are required and essential while elaborating a realistic model of the CGS shaking table. Also presented in this paper, is the numerical model of the shaking table that was established and validated.

This paper presents an experimental program carried out to investigate the behavior up to failure of composite wood-coldformed steel studs under monotonic and cyclic axial loading. The composite stud is made of a wood core incorporated inside a CFS C-channel. The main objective of the experiments is to quantify the ultimate strength, the energy dissipation capacity, and the failure mode of full-scale CFS-wood composite elements. For this purpose, eight fi xed-ended columns of 2320 mm in length were tested. The composite CFS C-studs with wood core were subjected to compression and tension monotonic tests in addition to two cyclic tests with diff erent loading rates. For comparison purposes, similar tests were conducted on bare CFS C-studs. The cyclic loading protocol was in accordance with FEMA 461 recommendations, with initial displacement obtained from the monotonic tests. The results revealed that a signifi cant gain of more than 80% in the average ultimate compression strength is achieved by the CFS-wood composite studs, and more importantly, the composite action enhances signifi cantly the energy dissipation capacity characterized by more stable hysteresis loops with less stiff ness and strength degradation. Finally, a detailed FE model using advanced interface modeling techniques, capable of predicting the ultimate strengths and the modes of failure, is elaborated and validated against the experimental results. The numerical model will be used eventually in future research work to optimize and improve the composite action.
