<br /> A. Are multiple lumber members fastened together to act as a single unit? ❑ Yes ❑ No
<br /> Spacing: Fastener type (nails, bolts,screws):
<br /> Hint: If bolts are used, there should be washers between the bolt head and nuts and the wood. And, the
<br /> drilled holes should be no larger than 1/16"over the size of the bolt.
<br /> B. Are all beam splices occurring over a support with at least 1%Z" of bearing? ❑ Yes El No
<br /> If no,describe location; (Needs attention)
<br /> C. Are there connections where the joist bears on top of the beam? El Yes ❑ No
<br /> Type of connection:
<br /> D. Joist: Size: Spacing: Span:
<br /> E. What is providing the minimum 11A" of bearing under the joists?
<br /> El Joist Hangers ❑ Ledger strips El Nothing(Needs attention)
<br /> Hint: Ledger strips must be nailed directly underneath the joist with 3 or 4 nails(depending on the
<br /> standard), concentrically placed right under the joist.
<br /> 1. Have any of the joist hangers been bent or modified? ❑ No ❑ Yes
<br /> Hint: Bending steel in the field may cause fractures at the bend line.
<br /> Fractured steel will not carry the load and must be replaced.
<br /> 2. Does the hanger have "double-shear"fastening? See Figure B. ❑ Yes El No
<br /> a. If the hanger has"double-shear"fastening,was the
<br /> I correct(full length)fastener used for the joist-to-header
<br /> fastener? See Figure "A"for incorrect nailing.
<br /> ❑ Yes El No (Needs attention)

<br /> F. What is providing lateral support for the deck diaphragm?
<br /> El Lateral load hardware ❑ Freestanding deck(blocking, bracing,etc.)
<br /> ❑ Nothing ❑ Unknown/Unable to Determine (Needs additional analysis)
<br /> Hint: Nails in joist hangers and ledger strips are subject to withdraw from the lateral forces and do not
<br /> perform well in withdraw. Therefore, the lateral forces must be addressed by some other means.
<br /> G. Are there any visible signs of red rust on the hardware (fasteners/connectors)? ❑ No ❑ Yes
<br /> If yes,where?
<br /> H. If connectors are used,are all the holes filled with the proper fasteners? El Yes El No .2/.'
<br /> If no,where?
<br /> Hint: Slotted or Phillips head screws are never appropriate for connectors.
