The mechanical response of post-tensioned glass beams is explored in this paper. This is done through bending experiments on post-tensioned glass beam specimens with either mechanically anchored or adhesively bonded steel tendons by which a beneficial pre-stress is inflicted on the glass beams. In addition, reference beams with identical geometry but without tendons are tested. From the results...

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...

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...

The present climate emergency demands the construction industry to minimise carbon footprint of concrete buildings. In this paper, potential different optimisation strategies reduce ‘cradle-to-gate’ embodied floors which require levels modifications conventional design and practice were compared. savings possible from parametrically optimising slab depth grade concrete, post-tensioning, conside...

PURPOSE The purpose of this study was to compare the bundle tension curves and resultant knee kinematics between 2 tensioning protocols in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction. METHODS Anatomic double-bundle ACL reconstruction was performed in 7 male cadaveric knees. Each graft was tensioned to 22 N under 2 conditions: (1) both bundles tensioned at 20 degrees...
