In recent years, steel-concrete composite shear walls have been widely used in enormous high-rise buildings. Due to their high strength and ductility, enhanced stiffness, stable cycle characteristics large energy absorption, such can be adopted auxiliary buildings, surrounding the reactor containment structure of nuclear power plants resist lateral forces induced by heavy winds severe earthquak...

The objective of this paper is to investigate the response of a cold-formed steel framed building subjected to earthquake excitation primarily through nonlinear time history analysis employing the incremental dynamic analysis (IDA) framework. The two-story archetype building from the Cold-Formed Steel – Network for Earthquake Engineering Simulation (CFS-NEES) project is analyzed using OpenSees....

Strengthening of the existing seismically deficient reinforced concrete (RC) buildings is an important issue in earthquake prone regions. Addition of RC shear wall as infill or external walls into the structural system has been a commonly preferred strengthening technique since the Big Erzincan Earthquake occurred in Turkey, 1992. The newly added rigid infill walls act primarily as shear walls ...

Based on shear strength reduction finite element method, stability of retaining wall with relieving plate has been analyzed. Due to the structure character of retaining wall with relieving plate, it can be found that fracture surface could hardly cross the triangle area of between lower wall and soleplate, between upper wall and relieving plate, so the second fractured surface occurred at there...

A grain level micromechanical analysis of ceramic microstructures subjected to dynamic compression–shear loading conditions is presented. The investigation consists of a combined experimental/numerical approach in which bulk and surface properties are examined by means of pressure–shear impact experiments for a ceramic plate in contact with steel plates. The model for the ceramic microstructure...

OBJECTIVE To determine whether selectin-mediated leukocyte-rolling velocity in inflamed venules in vivo is determined by wall shear rate (WSR) or by wall shear stress (WSS). METHODS WSS was manipulated independently of WSR by altering the viscosity of blood plasma in mice with an isovolemic exchange of blood for low- or high-viscosity dextran solutions. Rolling of neutrophils or beads coated ...

Removal of the whole sternum for malignant tumours results in a large defect, causing severe deformity and possible paradoxical movements of the chest wall. The reconstruction of the resultant large defect of the chest wall is often complex and difficult. Commonly used materials include rib autograft, steel strus acrylic plate and various synthetic meshes such as Goretex or Marlex mesh, with a ...

Advanced manufacturing processes such as near-net-shape forming can reduce production costs and increase the reliability of launch vehicle and airframe structural components through the reduction of material scrap and part count and the minimization of joints. The current research is an investigation of the processing-microstructure-property relationship for shear formed cylinders of the Al-Cu-...
