BACKGROUND One- and two-level lumbar interbody fusion with unilateral instrumentation is as effective as that with bilateral instrumentation. The height of the interbody cage influences the operated segment stability and the fusion technique success. The purpose of this research was to determine the effect of the fusion cage height (i.e. long and short) on both the stability (based on flexibili...

Analyzing piles subjected to lateral loads significantly depends on soil resistance at any point along the pile as a function of pile deflection, known as p-y curve. On the other hand, the deformation characteristics of soil defined as “the soil strain at 50% of maximum deviatoric stress (ε50)” has considerable effect on the generated p-y curve. In this research, several models are proposed to ...

This paper uses computational simulation to investigate the lateral load-displacement behavior and failure modes of a modern 14-story reinforced concrete (RC) core wall building. The design complies with minimum code requirements current California Building Code, which is based on ASCE 7–16 ACI 318–14. representation building, accounts for material nonlinearities all structural components, empl...

In embalmed preparations, the antebrachial fascia in the lateral elbow region is shown to be deformed by load application to the triceps muscle. From this fascia, muscles arise which are primarily concerned with the extension of wrist and fingers. In the case of lateral epicondylitis (tennis elbow), the superficial site of attachment of these extensors at the lateral epicondyle is extremely pai...

To study the residual lateral capacity of reinforced concrete (RC) columns after being subjected to static and horizontal impact action, tests a total sixteen RC were conducted. The variables considered in included shear-span ratio, weight velocity. experimental results, including force, deflection strain, as well cracking pattern failure mode, discussed. Compared with load–deflection curves un...

A possibility of recognition of the clinical status of patients with amyotrophic lateral sclerosis (ALS) in relation to severity of the disease was investigated. Three groups: (i) healthy controls (n=15) and two subgroups of ALS patients (ii) mild (n=15) and (iii) severe (n=15) were considered as classes. Four features of the subjects: (i) their age (AGE) (ii) erythropoietin concentration in se...

This paper presents a simple method to calculate pushover curves for asymmetric structure with displacement-dependent passive energy dissipation devices (DDPEDDs). The method analyzes the deformation of a symmetric structure in translation and in torsion. These results are then combined in order to calculate the pushover curve for an asymmetric structure with DDPEDDs. The numerical results obta...

Entire human cadaveric cervical spines with the basiocciput were subjected to load in a compression apparatus to simulate the clinical situation of forward dislocation. The movements were recorded by lateral cineradiography. Vertical load was measured by a potentiometric transmitter synchronised with each frame of the cineradiograph. The lower part of the spine was flexed and fixed, and the upp...

Slope reinforcement and the use of structural pile elements can be an effective slope remediation alternative when conventional remediation practices (e.g., improved drainage) fail to consider the causal factors leading to slope instability (e.g., strength loss due to weathering). An experimental research program was aimed at developing a rapid, cost-effective, and simple remediation system tha...

Steel Plate Shear Wall (SPSW) is made from thin steel plate which in turn are framed by the beams and columns of structural system. In recent year they are proved to be very effective and economical for resisting lateral loads such as earthquake and wind loads.The present work targets to study the behaviour of single frame SPSW with different plate thicknesses, rigid and non-rigid frame members...
