Structural Grid

The structural pattern is a result of a form which has been derived out of an Architectural mass modelling excercise. Fig.1 illustrates how the building is split into 3 to allow for a central square, creating a linkage and continuation of the main square. Horizontally the building grid is split at points to allow for access from Howard street

Horizontally the grid ranges from GL1 - GL12. The grids are spaced apart 6m c/c, except for the walkways which span 4.25m c/c.

Vertically, the grid ranges from GL(A) - GL(G). These are centred at 6m, with the central square being spaced at 5.5m c/c.

The grid has been setup to allow for a practical span range of 6m as illustrated in Fig.2. At some locations two-way spanning will be adopted, at some locations only oneway spanning will be possible. The only location with a longer span is the swimming pool area, where a span of 12m is required. This will be possible with one way joists or concrete beams as illustrated in Fig. 2.

Fig.2 also confirms that one way and two way concrete slabs are possible with a span range of 6m. It also confirms that timber beams will be more than feasible with a 6m span range.
