Anchor Bolt Approaches 50Th Anniversary

Oct 1, 2001 12:00 PM
Anchor Bolt & Screw Co, a third-generation, family-owned and operated fastener manufacturer and distributor, will soon celebrate 50 years in business.

When he incorporated the company Aug 21, 1952, Al Henriksen started with three employees who produced one cold-headed fastener from a small storefront on Chicago IL's near north side. In 1954, he relocated to a large building in Humboldt Park, a west side neighborhood. Increased fastener demand prompted Anchor Bolt & Screw to move in 1976 to the Chicago suburb of Melrose Park, where it remains today.

Marry Henriksen became owner when Al Henriksen, her husband, died in 1982. She is chairman of the board; her son, Pat, president and chief executive officer; his wife, Mitzy, vice-president of administration; and their daughter, Kim, executive vice-president and general manager.

Anchor Bolt & Screw opened a distribution center last year in Henderson NV to lower freight costs and provide quicker delivery times.

Initiation Of Failure

Failure initiated at the “weak-link” of the system – the anchor bolts on the eastern face, which were installed in the 1882 construction (Figure 6). The failure mode was separation within the anchor bolt system by one of two distinct modes.

Failure Mode 1 – Separation at the Boundary of 1882 and 1900 Construction – Expansion Bearing Anchor Bolt Collar Coupling

This mode accounts for approximately 3/4 of observed separation failures. All collar couplings observed at the site exhibit a radial cracking pattern. The equiangular cracks completely penetrate the collar couplings. The observed couplings either remained engaged on the bearing assemblies or are found loose within the debris field. Coupling fractures show evidence of fatigue fracture with secondary fractures occurring by overload presumably during the collapse. Many of the couplings were fractured by fatigue prior to the time of the collapse incident.

The 1900 construction provided washers “surrounding” the collar couplings. As a result, the collar couplings and associated cracking were “hidden” from view. The cracks within the collar couplings could only have been visually observed if the restraining bolts and washers were removed during an inspection cycle. Due to the complete penetration cracking of the couplings, a majority of the collar couplings were judged to be ineffective and could not transmit uplift forces to the substructure. Therefore, for analysis purposes, no uplift capacity was attributed at the locations where the 1882 anchor bolts remain in-situ, without attachment of collar couplings.

Failure Mode 2 – Ductile Failure (Separation) within the existing 1882 anchor bolts – Expansion Anchor Bolts.

This mode accounts for approximately 1/4 of observed failures. Fractographic examination of fractured original 1882 anchor bolts showed that the fracture resulted from tensile overload and was a fully ductile fracture. The estimated tensile capacity of one 1882, 1-1/4 inch anchor bolts at failure, assuming a 20% corrosion loss, is 30 tons. Based on the observed, 3:1 ratio of collar coupling separation to ductile anchor bolt failures, an uplift capacity of 30 tons per tower can be estimated. This capacity establishes a lower bound, critical wind speed of 94 mph, which was sufficient to initiate failure (see Figure 5). Failure was sudden and catastrophic.

Vulnerability to winds from the East Note that the structure was highly vulnerable; specifically to winds from the east due to the “separation” within the collar couplings of the “expansion” tower bearings. The anchor bolts on the “fixed” tower bearings - opposite face – did not employ collar couplings; hence, an uplift capacity of 152 tons (without section loss due to corrosion) can be estimated for the west legs. As a result, the structure was much less vulnerable to winds from the west – the prevailing wind direction. Winds from the west would result in base compressive and tensile forces, reversed in orientation from the forces effects illustrated in Figure 5.

Note that the failure of anchor bolts at the fixed bearings was similar to Mode 2 of the anchor bolt at the expansion bearings. The anchor bolts at the fixed bearings failed by simple tensile overload (ductile fracture) within the stem of the bolt. (See Figure 7.)

Threaded Rod Tool And Square Plates

Response to Comments
Thanks to everyone for your comments so far on the Threaded Rod and Square Plate thing.

I've had a chance to think all this over, and I'm thinking in a slightly different direction. Please tell me what you think of all this.

I created the Bent Bolt tool simply because it represented a type of bolt in the Fastener Standards book that an engineer friend of mine said should be included. In fact, all of these bolts are used as anchor bolts, and I probably made a mistake in calling it the Bent Bolt Tool. Perhaps the Anchor Bolt Tool would be a better name. After all, one of the bolts is a straight shaft, not bent at all.

It looks to me like the tool should have at least two additional styles of bolts. One would be a straight shaft with a square plate welded. The other would be a straight shaft with a square place trapped between two nuts.

In the case of the one with the nuts, we could have a Full Thread option, since Mike Emde likes to use threaded rods for this type of application.

I noticed in the Brown & Root specification from David Honan, that the bolts are shows with a sleeve at the top of the concrete. Should this tool have the ability to include a sleeve?

Clayton Hayes often uses straight anchor bolts embedded in epoxy. It looks like we ought to offer this in the tool.

Are there any other types of anchor bolts which should be include? I know expansion anchor bolts are common.

For an anchor bolt with an anchor plate held on with two nuts, we have a variety of nut types that can be used here. I would prefer to only use one type. We have Hex, High Hex, Heavy Hex and Heavy High Hex. Which would be the most commonly used? Hex nuts?

On the anchor plates, there are two ways I can handle this. One is to make the plates proportional to the diameter of the bolt. The other is to have a look-up table of the dimensions of the plate. We use a look-up table for the sizes of hex heads, washer diameter, etc. and I think this is probably the best way to go here. That means we will have a size and thickness for every English-measure and metric size, so please qualify your size suggestions by including the bolt size these are associated with.

What I'm talking about here are changes to the Bent Bolt tool. I still plan to do a Threaded Rod tool, but the anchor plate capability is a natural addition to the Bent Bolt tool.

Please let me have your comments.

A Threaded Rod tool will be great. I recall having to build many of these from other Bolt, Thread and Nut Tool combinations.

I guess I'd like to throw in that if you are going to have plates available, they should be created to a whole mm if the user has selected a metric thread.

Other thoughts (worms): If you do end up offering only 'fixed' thicknesses, I wonder if these could be proportional to the thread size selected? Typically a heavier bolt carries a larger load and therefore requires a heavier plate. The possibilities are endless...

The other thing about threaded rods is they have two ends and usually require drawing more nuts and washers etc. It would be nice to have the option to create the whole thing with a sequence of mouse clicks. Maybe two clicks in the same location could stop the tool from continuing and a quick Shift key hit while drawing would flip the nut washer combination. The figure below shows some possibilities that come to mind.

This would be great. I use a lot of threaded rods set in epoxy for anchors. When I use a plate, it is always a 3"x3"x1/4", so if this was on the washer list that would be nice.

The other thing that would be nice is to have an option where the embedded rod part is shown in a sleeve with the sleeve having a shade to it, which symbolizes the drilled hole and epoxy. Typically the hole is 1/8" oversize all around.

Thank you for continuing to develop this wonderful tool.
