ABSTRACT
The plan forms that may be considered at the concept design stage of modular buildings fall into well-defined types, which are described as follows.
5.2 CORRIDOR-TYPE BUILDINGS
The most commonly used modular construction system comprises a linear assembly of four-sided modules placed on either side of a central corridor, as illustrated in Figure 5.1(a). This arrangement is ideally suited for hotels, student accommodation, etc. From a structural point of view, wind forces on the front and rear façades are resisted efficiently by the side walls of the modules, whereas wind forces on the end gables are resisted by the highly perforated and hence weaker façade walls. This means that for efficient design, the building should be longer than it is deep. A simple relationship between the number of modules in a group and the building height is shown in Table 5.1.
