The section deformation distribution of reinforced concrete components is nonlinear due to the size effect. Existing analysis models such as plastic hinge and truss element are based on plane cross-section assumption. cannot be accurately simulated. Therefore, in this paper, non-planar strain functions sections established. law influence geometrical characteristics load distributions beam ends ...

Current formulations proposed by Eurocode 8 part 3 for the inelastic deformations of existing reinforced concrete members are assessed separately wide beams (WB) and conventional deep (DB). The current approach, based on a large experimental database members, predicts larger ultimate chord rotation but lower ductility WB rather than DB despite similar curvature ductility, due to plastic hinge l...

In general, the lateral confinement capacity of RC columns is influenced by strength and configuration transverse reinforcement. this study, performed antisymmetric flexural moment experiments that simulated seismic loads, with yield reinforcement square as main variables. The eight specimens were cross-sections measuring 250 × mm, effect in relation to variables was examined inducing failure p...

Nanoscale systems are forecast to be a means of integrating desirable attributes of molecular and bulk regimes into easily processed materials. Notable examples include plastic light-emitting devices and organic solar cells, the operation of which hinge on the formation of electronic excited states, excitons, in complex nanostructured materials. The spectroscopy of nanoscale materials reveals d...

OBJECTIVE To establish an optimal single hinge axis position for application of hinged external fixation to the elbow joint. DESIGN Cadaveric biomechanical investigation. SETTING A customized motion transducer applied passive elbow motion to six cadaveric upper extremities. The instant rotation axis of the humero-ulnar articulation was determined from three-dimensional kinematic data acquir...

This paper considers a lightweight boom with an integral hinge consisting of a thinwalled tube made of carbon fibre reinforced plastic with two longitudinal slots. The dynamic deployment of this boom is studied both experimentally and by means of detailed finite-element simulations. The deployment of the boom can be divided into three phases: deployment; incomplete latching, buckling of the tap...

During the fusion of the influenza virus to the host cell, bending of the HA2 chain of hemagglutinin into a hairpin-shaped structure in a pH-dependent manner facilitates the fusion of the viral envelope and the endosomal membrane. To characterize the structural and dynamical responses of the hinge region of HA2 to pH changes and examine the role of a conserved histidine in this region (the hing...
