Anchor strap

However, one additional requirement for blast resistant design should be considered. The presence of negative pressures and rebound forces require that wall to frame connections be provided to assure proper transfer of these outward acting forces. Figure 8,2 shows an application of anchor straps to handle rebound forces,...

Deteraiine the size and weight of the deadman required to counteract the buoyancy forces if required. Determine the size of anchor straps and bolts necessary to resist flotation.

Anchor straps should be made of flat bar in the area with contact with die shell. However the anchor strap must be isolated from contact with the tank shell by use of a gasket. 

Optional) Bend bolt for trigger. Drill hole in stock and place bolt in hole so strap will be anchored by boU when pulled back If bolt is not available, use strap as trigger by pulling back and releasing. 

Make no mistake, when it comes to fall protection systems and equipment, OSHA (and common sense) require hands-on learning that approximates actual work conditions. If we re talking about a harness for example, there is no substitute for strapping into it, connecting to an anchor, experiencing how it feels, and seeing firsthand what needs to be inspected before use.

Add value of U to upfift calculation for design of straps and/or anchor bolts. 

Steel plates were fixed into the columns and beams to anchor the straps. 

Joints were strengthened with horizontal straps anchored to the steel plates (2 layers). 

Use appropriately sized cable/wire anchors that are permanently affixed to the surface. Self-adhesive anchors are not acceptable unless mounted by screws. All cable/wire straps shall be appropriately sized, spaced and tensioned to avoid cable/wire insulation deformation/damage and provide adequate support. Replace nicked or cracked wire insulation. 

A major problem is the anchoring of skin-surface electrodes to maintain reasonably constant contact-impedance and to prevent motion artifacts. Usual techniques involve elastic bands and adhesive tape. Conventional metal electrodes generally require the use of an electrode paste to maintain contact and reduce motional problems. Pasteless electrodes as described in Section 8.3 avoid most of the problems associated with conventional metallic electrodes, but they still must be held in place by a strap or belt. 

If EKG s are recorded in a Faraday-shielded room using shielded lead wires, records as shown in Figure 10.1c,d can be obtained. Note the absence of 60-Hz interference. In Figure 10. Id, leads I and III exhibit thickening, but this results from muscle tremor signals. The source is the left arm, since this limb is common to both leads. Apparently the strap which anchored the left wrist electrode was too tight, and some EMG signals were produced. 

Numerous steel tanks, especially tall (slender) tanks, are anchored with bolts or straps. However, these anchors may be insufficient to withstand the total imposed load in strong earthquake events and can be damaged, in the form of anchor pullout, stretching, or rupture. One should consider that failure of an anchor does not necessarily lead to tank collapse or loss of tank contents. On the other hand, failure of a significant number of bolts may lead to failure of the tank supporting system and eventually to tank overturning and loss of contents.
