Failure to correctly tension grafts may overconstrain or underconstrain the knee, potentially predisposing the patient to deteriorating clinical and/or radiographic results over time. Knee ligament reconstruction requires a fundamental understanding of native anatomy, ligament biomechanics, and principles of graft tensioning. A successful strategy for graft tensioning takes into account the spe...

This paper discusses the behaviour characteristics of the shaping formation of Single-Chorded Space Truss (SCST) structures by means of cable-tensioning of bottom chords. The innovative technique is fast and economical and issued in many types of space structures. The small-scale test models presented herein consist of uniform pyramids with multi-directional ball type joints which are erected i...

BACKGROUND Alarmins, endogenous molecules released on tissue damage have been shown to play an important role in inflammatory musculoskeletal conditions including fracture repair andrheumatoid arthritis. However, the contribution of alarmins to the pathogenesis of tendon disease is not fully understood. METHODS We investigated expression of alarmin proteins (S100A9, high-mobility group box 1 ...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

With the aim of achieving stable operation of circular saws, this study finds the solution for the optimization problem that involves choosing a set of tensioning parameters in a rotating circular saw that is subjected to both a local temperature distribution and the in-plane plastic strain over a double annular domain. The solution for the in-plane forces is obtained on the basis of plate bend...

Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive impact on the seismic behavior of structural systems, but their design makes them susceptible to concrete crushing around their base, which can lead to significantly advers...

This research presents experimental and theoretical investigation of 15 reinforced concrete spliced nonspliced girder models. Splices hooked dowels cast in place joints, with or without strengthening steel plates were used. Post-tensioning had been used to enhance the splice strength for some girders. The ANSYS computer program was analyzing non-spliced A nonlinear three dimensional element rep...
