Planning Module Applications: Design Configurations
251.3
ASSEMBLY CHARACTERISTICS OF THE SERVICE MODULE
The assembly characteristics of the service module are primarily
established by:
1. The structural subsystem
2. The service bay
3. The space module, when the service module occurs in the bed-care
portions of the hospital.
251.3.1
The Structural Subsystem
Those features of the structural subsystem which most markedly affect the
assembly of modules are the structural bay, the shear wall, and the
thermal expansion or seismic separation joint.
1. The Structural Bay
The constant width and variable length of the structural bay produce offset
column lines when two space modules or service modules adjoin at right
angles. This problem can best be resolved through the use of the 45'
span, although the modular structural bay lengths create a regular
condition in any case. (See Sections 316.4 and 721.1.2 for further
discussion.)
2. Shear Walls
Configurations are affected in several ways by the use of shear walls to
resist lateral forces.
