7.0 CONDITIONS OF USE
The National Evaluation Service Committee finds that
StrucLam LVL are acceptable materials, products or methods of construction to those
specified in the BOCA National Building Code/1996, 1997 Standard Building Code and 1998
Revisions and the 1997 Uniform Building Code subject to the following
conditions:
7.1 Willamette StrucLam LVL shall be produced at the
Willamette Industries, Inc., facility in Winston, Oregon, or Albany, Oregon, or Simsboro,
Louisiana, with quality control inspections by APA - Engineered Wood Systems (NER-QA397).
7.2 Design calculations and details for
specific applications shall be furnished to the code official verifying compliance with
this report and the applicable code. The individual preparing such documents shall possess
the necessary credentials regarding competency and qualifications as required by the
applicable code and the professional registration laws of the state where the construction
is undertaken.
7.3 Where applicable. Tables 2,3,4,5 and 6
are intended to serve as an alternative to that portion of the design calculations.
7.4 Design stresses for StrucLam LVL shall
not exceed those given in Table 1 of this report. Allowable design capacities shall be
adjusted for the appropriate duration of load factor in accordance with the applicable
code for solid sawn lumber.
7.5 Fastener design values shall be as
specified in Section 3.2.2 of this report.
7.6 The service conditions for StrucLam
LVL shall be covered, dry conditions of use. Dry conditions of use are those conditions
represented by sawn lumber in which the moisture content is less than 16 percent.
7.7 The scope of this report does not
include the effects of holes or notches in any StrucLam member.
7.8 Installation of StrucLam LVL shall comply with
the manufacturer's recommended installation instructions and this report.
7.9 The scope of this report shall be
limited to StrucLam LVL which has not received pressure treatment. including fire
retardants or preservatives.
7.10 The scope of this report is limited
to StrucLam LVL structural members, as described in Section 3.0 of this report, and does
not include building components which connect to the StrucLam member, or which are
supported by it.
7.11 This report is subject to periodic
re-examination. For information on the current status, consult the evaluation report
listing or contact one of the participating members of the NES. |
