Abstract The ways of designing and building steel girder bridges with a composite concrete deck vary much between different parts the world. A bridge system twin I‐girders or concept multiple (more than two) girders can be used. design use details secondary systems also lot. In order to give horizontal stabilization distribute loads, bracing bracings are often Although not so common, used verti...

There are several advantages to accurate reproduction of knee motion in an external joint assembly such as a knee brace: reduction of pistoning forces, better ligament protection, kinematic compatability. The geometry and kinematics of the normal human knee were studied and the results applied to external joint design. Geometrically, the posterior portions of the femoral condyles were found to ...

The design and behavior of a ductile structural system called a knee-braced moment frame are presented in this paper. The design of this structural system is based on a capacity-design concept that results in ductile behavior. The knee part is a fuse-like component that dissipates energy by the formation of plastic flexural and/or shear hinges at its ends and mid-span, when the building is subj...

BACKGROUND changes in lower-limb joint moments are important outcome measures for treatment and prevention of knee osteoarthritis. However, it is known that both the magnitude and amplitude of joint moments are affected by the choice of anatomical reference frame. The purpose of this study was to identify features of joint moment waveforms that, regardless of the choice of reference frame, are ...

The primary focus of this investigation was to analyze sequentially coupled nonlinear thermal stress, using a three-dimensional model. It was meant to shed light on the behavior of Buckling Restraint Brace (BRB) elements with circular cross section, at elevated temperature. Such bracing systems were comprised of a cylindrical steel core encased in a strong concrete-filled steel hollow casing. A...

Background The optimal postoperative rehabilitation protocol following repair of complete proximal hamstring tendon ruptures is the subject of ongoing investigation, with a need for more standardized regimens and evidence-based modalities. Purpose To assess the variability across proximal hamstring tendon repair rehabilitation protocols published online by United States (US) orthopaedic teach...

The objective of this paper is to explore the potential impact of the use of advanced high strength steel (AHSS) to form traditional cold-formed steel structural members. In this study, shell finite element models are constructed, and geometric and material nonlinear collapse analysis performed, on simulated lipped channel cross-section cold-formed steel members roll-formed from AHSS. AHSS shee...

The objective of this paper is to assess the promise of a novel tool for structural safety decisionmaking in severe unforeseen hazards. A straightforward measure is put forth for measuring the intensity of unforeseen hazards: the number of connected members removed from a structure in a brittle fashion. The tool selected for assessing this severe demand is the reduction in the buckling load cap...
