Cyclic Tests on External RC Beam-Column Joints: Role of Seismic Design Level and Axial Load Value on the Ultimate Capacity

open access: closedJournal of Earthquake Engineering, 2012
A wide experimental program on beam-column RC joints carried out in the framework of the DPC-Reluis Project (DPC: Department of Civil Protection, Reluis: Network of University Laboratories of Earthquake Engineering) is presented. All the experimental tests were performed at the Laboratory of Structures of the University of Basilicata, Potenza, Italy ...

Dose dependent inhibition of bone loss by low level, high frequency mechanical loading of the lower appendicular and axial skeleton of post-menopausal women

open access: closedProceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
Correlation of changes in bone mineral density in the human lumbar spine, femoral neck and greater trochanter, against total duration of exposure to a 30 Hz, 0.2 g mechanical loading over a one year period (range of 2000-9000 seconds), demonstrates a strong positive relationship between treatment duration and inhibition of bone loss ...

Stress Level Prediction in Axially-Loaded Timber Beams Using Resonance Frequency Analysis: A Pilot Study

Advanced Materials Research, 2013
The structural integrity due to problems in the uncertainties of load, the load-carrying capacity of timber structures is of great importance, since peaks of increased loads might occur. One solution of these problems lies in the evaluation of timber structures using non-destructive testing (NDT) methods, and in this special case frequency based ...

Multi-level residue harmonic balance solution for the nonlinear natural frequency of axially loaded beams with an internal hinge

Mechanics of Advanced Materials and Structures, 2016
ABSTRACTIn this article, an analytical approach, namely, multi-level residue harmonic balance is introduced and developed for the nonlinear free vibration analysis of axially loaded beams with an internal hinge. The main advantage of this method is that only one set of nonlinear algebraic equations is required to be solved for obtaining the zero level ...
