Part 2: Concept Design 2 - 31 1 1 Division plate Figure 4.5 Typical splice details with bearing plate If there are restrictions on space, it is possible to use countersunk bolts in the plates, or if the colum n sections have th e same internal profile, to use internal cover plates and countersunk bolts, as shown in Figure 4.6.

Typical solutions are given in Table 4.2, and more details in the fo llowing sections. Although steel solutions are app ropriate for short spans (typ ically 6 m to 9 m), steel has an im portant advantage over other m aterials in that long span solutions (between 12 m and 18 m) can be easily provided. This has the key advantage of column-free space, allowing future adaptability, and fewer foundations.
