Due to the scarcity of rational models for predicting the strength of RC beam-column sandwich joints, a modified simplified softened strut-and-tie model suggests a more rational calculation method for the effective compressive strength and the height of the joint concrete based on the simplified softened strut-and-tie. The shear strength of existing tested 15 sandwich interior joints is calcula...

The roll center is one of the key parameters for designing a suspension. Several driving characteristics are affected significantly by the migration of the roll center during the suspension’s motion. The strut/SLA (strut/short-long-arm) suspension, which is widely used in production cars, combines the space-saving characteristics of a MacPherson strut suspension with some of the preferred handl...

AIM Percutaneous coronary intervention (PCI) for severe calcified lesions is still challenging, and there are few studies of drug-eluting stent (DES) implantation for severe calcified lesions, especially regarding long-term results and hemodialysis patients. The study purpose was to clarify the factors, including DES strut thickness, that affect the long-term outcome of severe calcified lesion ...

OBJECTIVES/HYPOTHESIS The maxillary strut is the bone that separates the foramen rotundum and superior orbital fissure. Tumors involving the lateral wall of the sphenoid sinus, posterior ethmoid, or posterior maxillary sinus may invade this region. The authors detail the anatomy of the strut and present a case series that emphasizes the importance and utility of this useful landmark during an e...

OBJECTIVES This study sought to evaluate the relationship between post-stent strut apposition and follow-up strut coverage using contour plot optical coherence tomographic analysis. BACKGROUND Tracking the fate of interested regions of struts at different time points has not been investigated. METHODS Post-intervention and 6-month follow-up optical coherence tomographic evaluations were per...

BACKGROUND AND PURPOSE Radiographic visibility of self-expandable intracranial stents is insufficient for assessment of conformability and deployment characteristics. The purpose of this study was to evaluate stent mechanics in a curved vessel model by using Flat-Panel CT (FPCT). MATERIALS AND METHODS The following stents were used: Neuroform 2, Neuroform Treo, Enterprise, and LEO. All stents...

A set of analytical models based on engineering beam analysis is developed to predict creep behavior of cellular materials over a broad range of relative density. Model predictions, which take into account the presence of mass at strut nodes and consider different possible deformation mechanisms and foam architectures, are compared to experimental creep results for a replicated nickel-base foam...

Study Design Retrospective study. Purpose The purpose of this study was to investigate the influence of sagittal alignment of the strut graft on graft subsidence and clinical outcomes after anterior cervical corpectomy and fusion (ACCF). Overview of Literature ACCF is a common technique for the treatment of various cervical pathologies. Although graft subsidence sometimes occurs after ACCF,...

The current research work summarizes some previous works on horizontally curved beams. Because of curvature, torsional effects in the analysis and design should be included. Diameter ring beam, number supports, beam width, compressive strength concrete, bearing plate width. Which can summarized from studies is that increasing diameter by about 25-75% decreases capacity load 14-36%, while suppor...

in this paper a new method based on strut-and-tie model (stm) is proposed to determine the shear capacity of simply supported rc deep beams and an efficiency factor for concrete with considering the effect of web reinforcements. it is assumed that, the total carried shear force by rc deep beam provided by two independent resistance, namely diagonal concrete strut due to strut-and-tie mechanism ...
