California Building Codes
The openings must have a net area of 1 square foot for each square feet of under floor area and should be located to provide cross ventilation. The thickness of plywood will be determined by your joist spacing and the panel identification index of plywood selected for use.
All plywood flooring edges must be tongue and groove joints or must be supported with blocking. Exterior wall sill plates bearing on concrete must be pressure treated lumber.
Bolts must not be spaced over 6 feet apart. A minimum of two bolts are required per piece. Studs shall be placed with their wide dimension perpendicular to the wall. At least three studs need to be installed at each corner of an exterior wall. End joints in double top plates must be offset by at least 4 feet. This applies to metal diagonal braces as well as wood. The only method of wall bracing now allowed other than an engineered design is Braced Wall Panels.
They are similar to shear panels, but they need not be designed by an engineer for a particular location. The CBC lists 7 types of Panels which can be used in our earthquake zone. This term includes not only plywood, but OSB and similar products. Nailing is 6" o.. Braced Wall Panels must be at least 48" wide, except that gypsum wallboard Panels must be 96" wide if applied to one side of the wall, and 48" wide if applied to both sides.
They must extend from the floor to the ceiling, or if there is no ceiling, to the roof. All vertical joints of Braced Wall Panels must be on studs and all horizontal joints must be blocked.
The bottoms of Braced Wall Panels must be attached in the following manner: Wood Floor: Bottom plates of the panels should be nailed to floor framing with 3 16d nails every 16". This usually requires putting extra joists or blocking in the floor frame to provide backing for the interior panels.
Slab Floor or Foundation: Bottom plates of panels in exterior walls must be attached to the slab or foundation with anchor bolts. Interior panels must be attached with anchor bolts or with 3" shots placed 6" and 10" from each end, plus 18" o..
The shots must be a type which are listed for this use. The tops of Braced Wall Panels must be attached to the floor above if there is one, to the ceiling, or if the building has no ceiling, such as a garage, the tops of the Panels must extend up to the roof. Each Braced Wall Panel must be shown on the plans with an indication of which type it is, and with enough dimensioning to show that it meets the location requirements described under Braced Wall Lines below.
The requirements are as follows: 1 Minimum width is 32" and maximum height is 10'. Cripple walls are not permitted below Alternate Panels. For the first story of a two-story building, the plywood must be on both sides of the Alternate Panel. For the first story of a two-story building, the uplift rating must be at least pounds.
In order for a wall line to be considered a Braced Wall Line, it must have Braced Wall Panels no more than 8' from each end and no more than 25' to throughout the entire length of the wall line. These panels must be in line or offset from each other no more than 4'.
If the Braced Wall Panels consist of gypsum wallboard applied to one side of the wall, the required percentage must be doubled. There are no requirements for the wall between the panels, in fact there need not be any wall between the panels. A Braced Wall Line can consist only of the required Braced Wall Panels, located as described above, with the bottoms properly attached to the floor or foundation, and the tops attached to the floor above, the ceiling, or the roof.
All non-engineered buildings must have Braced Wall Lines throughout, running in both directions front to back and side to side. The maximum distance between parallel Braced Wall Lines in the City of San Bruno it varies with wind and seismic zones is 25'. The exception is that the house can have one room with a maximum 34 23 12 between braced wall panels.
That room is limited under this exception to square feet. Therefore, generally, the building must be divided into boxes which are no more than 25' in either direction, and each side of each box must be a Braced Wall Line or part of a Braced Wall Line. Remember that, if these bracing requirements are too restrictive for the design you prefer, you may submit plans with the bracing designed by a California licensed architect or engineer.
Unusually Shaped Buildings: This term is used in the California Building Code to describe wood-framed buildings which require engineering. It includes a list of conditions which automatically put a building into that category. Laterally unsupported edges of floors and roofs are one of the above-mentioned conditions. Generally, all edges of floors and roofs must be laterally supported by Braced Wall Lines.
This becomes an issue in floors with open edges such as balconies and mezzanines, and in open roofed structures such as patios and carports.
An exception is made for floors and roofs which extend no more than 6' beyond a supporting Braced Wall Line.
It also becomes an issue with cantilevered roofs, whether trusses or rafters, where the roof is not directly connected to the top of the Braced Wall Line, and therefore not laterally supported by it. This latter situation can be remedied by extending the Braced Wall Panels past the ceiling up to the roof. This involves building the panels around the ceiling framing or trusses. Angles between Braced Wall Lines other than 90 degrees is another condition which automatically requires engineering.
When exceeding four feet in height, such walls shall be framed of studs having the size required for an additional story. Such walls having a stud height exceeding fourteen inches shall be braced in accordance with Table IV-C Solid blocking or plywood sheathing may be used to brace cripple walls having a stud height of fourteen inches or less.
Remember that methods 1 and 7 cannot be used to brace cripple walls in seismic zone 4. Some shearwalls required tighter nail spacing. Framing members or blocking shall be provided at the edges of all sheets in Braced Wall Panels and shearwalls. Studs in exterior walls and bearing walls must not be cut or notched more than 25 percent of their width i.
Cutting or notching up to forty percent of stud width is permitted in non-bearing partitions.
A bored hole not exceeding forty percent of the stud width i. If holes up to sixty percent of the width of the stud are made, the wall studs must be doubled, and no more than two successive studs can be bored.
Holes up to sixty percent of the stud width can be made in non-bearing walls without doubling i. The vertical distance between blocking shall not exceed ten feet. It is also required where a ceiling is below the top plate of the wall such as soffit ceilings, and around the edges of tubs and showers on wood floors.
The primary application of a building code is to regulate new or proposed construction. Building codes only apply to an existing building if the building undergoes reconstruction, rehabilitation or alteration, or if the occupancy of the existing building changes to a new occupancy as defined by the building code.
