Every driveway bridge and portion thereof for vehicular access to private garages or private parking shall be designed and constructed as a minimum in accordance with the general requirements of this Code as amended by this Section.

This Section provides design loadings for driveway bridges, driveway approach decks, garage floors, and carport floors. Secondly, this division provides for minimum prescriptive requirements for alterations or repairs of varying scope to existing driveway bridges. This Section considers the possibility of temporary heavy loads on unroofed vehicle approach decks due to construction equipment, moving vans, and heavy emergency or other vehicles using the deck. On these bases, the appropriate design loads have been determined.

this division provides for minimum prescriptive requirements for alterations or repairs of varying scope to existing driveway bridges. This Section considers the possibility of temporary heavy loads on unroofed vehicle approach decks due to construction equipment, moving vans, and heavy emergency or other vehicles using the deck. On these bases, the appropriate design loads have been determined.

In all cases lateral loads for wind or seismic shall be considered and provided for. Repairs and alterations of existing decks shall conform to the criteria pursuant to this Chapter.

Section 1602B - Design Loads.

Section 1602B.1 Case I.

Design loads for driveway bridges serving private residential parking garages/carports with restricted headroom and no repair or refueling. Design loads shall be pursuant to Chapter 16 of the California Building Code for concentrated load and uniform live load (Private or pleasure-type motor vehicle storage). Reduction of live load may be determined pursuant to Chapter 16 of the California Building Code. Design load summary as follows:

Wheel load:

Two (2) 2,000 lb. loads spaced five (5) feet apart.

Each concentrated load is to be placed upon any space a maximum of two and a half (2½) feet square pursuant to Chapter 16 of the California Building Code.

Uniform load:

One hundred (100) PSF with no allowable stress increase for duration of load. Live load reduction may be pursuant to Chapter 16 of the California Building Code.

Section 1602B.2 Case II.

Design loads for private vehicle access bridges serving a single-family dwelling on a single lot fronting unimproved streets where the length of the building access path crossing the driveway bridge is fifty (50) feet or less. The following loads apply to the portion of such vehicle access bridges in the public right-ofway as well as the portion on private property. Pursuant to Chapter 16 of the California Building Code, this Section considers the gross weight of the maximum vehicle served to be twenty thousand (20,000) pounds for this condition (AASHTO H10 loading). The length of the access path is measured from the edge of pavement of the unimproved street to the building/garage/carport entry point. This concentrated load may be distributed in accordance with the provisions Chapter 16 of the California Building Code or, alternatively, the concentrated loads may be distributed in accordance with the Standard Specifications For Highway Bridges, 14th ed., 1989, or latest edition, as adopted by the American Association of State Highway and Transportation Officials, 444 North Capitol Street, N.W., Suite 225, Washington, D.C. 20001. Allowable stress increases for a load duration of seven (7) days may be used for this concentrated load.

A minimum uniform live load of one hundred (100) PSF, (Garages—General storage and/or repair of the California Building Code), shall be used. Reduction of live loads may be determined pursuant to Chapter 16 of the California Building Code. The condition of concentrated or uniform live load producing the greater stresses shall govern. The summary of these loads are as follows:

Wheel load:

Two (2) 8,000 lb. loads spaced five (5) feet apart.

Each concentrated load is to be placed upon any space a maximum of two and a half (2½) feet square.

May alternatively use AASHTO load distribution.

Uniform load:

One hundred (100) PSF with no allowable stress increase for duration of load. Live load reduction pursuant to Chapter 16 of the California Building Code.

Section 1602B.3 Case III.

Same As Case II, except building entry access path crossing the driveway bridge is more than fifty (50) feet. Same as for Case II, except the gross vehicle weight considered shall be thirty thousand (30,000) pounds (AASHTO Hl5).

Wheel load:

Two (2) 12,000 lb. loads spaced five (5) feet apart.

Each concentrated load is to be placed upon any space a maximum of two and a half (2½) feet square.

May alternatively use AASHTO load distribution.

Uniform load:

One hundred (100) PSF with no allowable stress increase for duration of load. Live load reduction pursuant to Chapter 16 of the California Building Code.

Section 1602B.4 Case IV.

Design Load for Private Residential Access Bridge Serving More than One Dwelling Unit or More than a Single Lot Fronting an Unimproved Street.

Design loads shall be the same as for Case III in this Chapter.

Section 1603B—Alterations or Repairs to Existing Driveway Bridges.

Section 1603B.1 Case V.

Existing driveway bridges may need repairs as their structural system or moisture barrier system is often inadequate. Plans with the permit submittal, including concrete deck removal to install new deck waterproofing, for driveway bridge repairs should show the existing structural system for the driveway bridge so its adequacy to the design criteria of this Section may be checked.

A structural evaluation by an architect or engineer of the structure based on the design load criteria of this Chapter, as appropriate, shall be provided for any driveway bridge repair for a bridge that does not have documented structural calculations.

Section 1603B.2 Case VI.

If there are practical constraints on accomplishing repair work to a bridge with a history of adequate performance, the following alternative minimum prescriptive requirements for driveway bridge repairs, when approved by the Building Official, may suffice in lieu of a structural evaluation pursuant to this Chapter:
