Los Angeles County Municipal Code Ch. 31 Special Construction

SECTION 3114 - INTERMODAL SHIPPING CONTAINERS

. . .

Exceptions:

. . .

Single-unit stand-alone intermodal shipping containers used as temporary storage or construction trailer on active construction sites. Construction support facilities for uses and activities not directly associated with the actual processes of construction, including, but not limited to, offices, meeting rooms, plan rooms, other administrative or support functions shall not be exempt from Section 3114.

. . .

3114.8.4   Detailed structural design procedure.

A structural analysis meeting the requirements of this Section shall be provided to the building official to demonstrate the structural adequacy of the intermodal shipping containers.

3114.8.4.2   Seismic design parameters.

The seismic force-resisting system shall be designed and detailed in accordance with ASCE 7 and one of the following:

. . .

Where all or portions of the profiled steel panel elements are retained and integrated into a seismic force-resisting system other than as permitted by Section 3114.8.4.2, Item 1, seismic design parameters shall be developed from testing and analysis in accordance with Section 104.2.9 and ASCE 7, Section 12.2.1.1 or 12.2.1.2.

. . .

3114.8.5.2   Structural design assumptions.

Where permitted by Section 3114.8.5.1, single-unit, stand-alone intermodal shipping containers shall be designed using the following assumptions for the profiled steel panel side walls and end walls:

The appropriate detailing requirements contained in Chapters 16 through 23.

Response modification coefficient, R = 2,

Over strength factor, Ω0 = 2.5,

Deflection amplification factor, Cd = 2, and

Limits on structural height, hn = 9.5 feet (2900 mm).

3114.8.5.3   Allowable shear.

The allowable shear for the profiled steel panel side walls (longitudinal) and end walls (transverse) for wind design and seismic design using the coefficients of Section 3114.8.5.2 shall be in accordance with Table 3114.8.5.3, provided that all of the following conditions are met:

. . .

All side walls or end walls used as part of the lateral force-resisting system shall have an existing or new boundary element on all sides to form a continuous load path, or paths, with adequate strength and stiffness to transfer all forces from the point of application to the final point of resistance, as shown in Figure 3114.8.5.3(3). The existing door interlocking mechanism shall not be considered as a component of the required load path.

. . .
