The objective of this paper is to provide the stiffness and strength characteristics for coldformed steel stud walls stabilized by sheathing. The primary stability resistance is provided by translational (lateral) stiffness supplied at the fastener locations to the cold-formed steel studs. This paper separates the source of this translational stiffness into two parts: local and diaphragm. To an...

The strength of sheathed wall systems is substantially greater than unsheathed walls with the same studs. Testing on studs sheathed on both sides with dry gypsum board demonstrate strength increases as large as 70% over unsheathed studs (Miller and Peköz 1993, Miller and Peköz 1994). The current AISI Specification for sheathed wall stud systems are complicated, only apply when the sheathing is ...

A case of arteriosclerotic retinopathy associated with retinal venous thrombosis was treated with Anginin and the following results obtained: 1) Visual acuity was improved from 0.03 to 0.7. 2) Retinal hemorrhages were absorbed and pipe-stem sheathing of the branch of retinal artery decrease, with white sheathing remaining partially. 3) It was therefore considered that the pipestem sheathing was...

Rucker (I944) was first to describe sheathing of retinal veins in patients with multiple sclerosis. This was supported by later observers (Treusch and Rucker, 1944; Haar, I953; Scott, I96I), but the incidence was found to vary from IO to 23 per cent. It was initially thought that this periphlebitis was not associated with other ocular conditions, and might indicate a possible pathological basis...

A pale yellow liquid was found in the vacuum scattering vessel which neutron detector is installed on BL02 spectrometer J-PARC MLF. The substance characterized as phthalic acids, are known plasticizers for poly(vinyl chloride) cable sheathing. leakage mechanism of needs to be urgently clarified, they contaminate and could cause background increase experimental data. We purchased commercially av...

damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...

A common lateral force resisting system for cold-formed steel (CFS) buildings consists of shear walls sheathed with oriented strand board (OSB). Previous experimental and computational research on CFS shear walls, as well as those with other framing materials, has demonstrated that the complex interaction of the fasteners with the sheathing is an important factor in the nonlinear behavior of th...

A series of observations of polymer sheathing in multiwalled carbon nanotube (MWCNT)−polycarbonate composites are presented. This sheathing was observed in images of the composite fracture surface and is consistent with diameter distributions of the as-received and embedded MWCNTs. A novel nanomanipulation experiment, where the sheathing balls up when contacted by an AFM tip, confirms this phen...
