STRUCTURAL DESIGN
SECTION 1609 WIND LOADS

Per the Basic Wind Speed Figures, use the following:
Risk Category I – 100 mph
Risk Category II – 105 mph Risk Category III – 110 mph Risk Category IV – 115 mph
ADD new Section 1609.5.1.1 as follows:
“1609.5.1.1 Uplift resistance to minimize microburst effects. In addition to requirements in ASCE 7, minimum uplift resistance shall be determined by either method 1 or 2 below:
1.
Design-based wind uplift criteria Wind uplift requirements shall be determined by using the design wind value of 110 mph within Table 2308.7.5 for the continuous load path transmitting the uplift forces from the rafter or truss ties to the foundation.
2.
Prescriptive-based wind uplift criteria (Please note that the requirements of this Section are in addition to those required for the structural connection of wood members)
a.
Conventionally-framed wood or cold-formed steel structures All bearing wall vertical connections shall be clipped with either approved structural sheathing or approved clips to provide a continuous load path from the joist or truss through the ledger or top plate to the bottom wall plate. Where clips are used, they shall be minimum Simpson H2.5 (A34 at ledger), or equivalent load capacity, of configuration to match connection and spaced at intervals not to exceed 24." At openings, lower cripple studs do not require clipping but king/trimmer studs require double clips at bottom and upper cripples require both full clipping to header as well as header to king stud. All platform framing requires either strapping listed for the purpose or continuous sheathing over rim joist from stud to stud vertically at each floor level. All non-bearing exterior walls shall be clipped as above except that the spacing may be extended not to exceed every other stud.
b.
Masonry or concrete structures If lateral design requires larger anchors or more conservative spacing, these may be used in lieu of those called out in this Section.
i.
Roof bearing on wall top plate Top plates shall be secured to masonry or concrete walls with minimum 0.5" anchor bolts embedded minimum 7” and spaced at intervals not to exceed 48." Each joist or truss shall be clipped to plate at bearing with minimum Simpson H2.5 or equivalent load capacity and of configuration to match connection. Gable end joists or trusses shall also be clipped at intervals not to exceed 48.”
ii.
Roof bearing on wall ledger Joists or trusses bearing on a wall ledger shall be secured to masonry or concrete walls with minimum Simpson PAI23 purlin anchors or equal with equivalent load capacity listed for the application and embedded into wall per listing at intervals not to exceed 48”. Nonbearing roof diaphragm edges shall have the outermost joist or truss likewise anchored to the wall through blocking.
c.
Structural steel structures Structural steel buildings shall have roof members attached by either welds, bolts, screws or other similarly approved connections at intervals not to exceed 48". Ledger designs shall connect to roof trusses with strapping listed for the purpose at intervals not to exceed 48" on all diaphragm sides. If lateral design requires larger anchors or more conservative spacing, these may be used in lieu of those called out in this Section.
SECTION 1610 SOIL LATERAL LOADS
Add the following section:
“Section 1610.1.1 Presumptive active pressure. For typical unsaturated soils within Pima
County, a presumptive active lateral pressure of 35 psf per foot of depth may be used without a geotechnical report. Level backfill is assumed with this active pressure. Surcharges shall be applied as
necessary.”
CHAPTER 17
SPECIAL INSPECTIONS AND TESTS
SECTION 1705 REQUIRED SPECIAL INSPECTIONS AND TESTS
Section 1705.4 Masonry Construction. REVISE Section by ADDING a new exception item 4 as follows:
4. Non-essential facilities designed in accordance with Section 2107 with allowable masonry stresses reduced by one half and the maximum value of f ’m limited to 1500 psi for concrete or clay masonry. The following limitations shall apply to this exception:
1. The unsupported height (or length)- to- thickness ratio of a building wall shall not exceed 20
2. The soil retaining height for a wall retaining wall shall not exceed 4’-0’ measured from the top of footing for an 8-inch-thick wall or 6’-0’ for a 12- inch- thick wall.
3. The height- to- thickness ratio shall not exceed 10 for a cantilevered masonry fence or
combination masonry fence and retaining wall as measures from the top of footing to the
top of the wall. If a combination retaining/fence wall consist of more than one wall
thickness, the smallest thickness shall be used in determining the height-to-thickness
ratio
Any portion or portions of a structure in which the design masonry stresses exceed one half the allowable masonry stresses, shall require Special Inspection for that portion or portions of the structure.
CHAPTER 18
SOILS AND FOUNDATIONS
SECTION 1806 PRESUMPTIVE LOAD-BEARING VALUES OF SOILS
Add the following section:
“Section 1806.2.1 Presumptive coefficient of friction:
For typical unsaturated soils, a presumptive coefficient of friction of 0.30 for lateral sliding resistance may be used without a geotechnical report. Friction resistance may be used in conjunction with passive pressure to resist sliding forces.”
