end, above the end support (Fig. 6). Each individual tank was placed on a wooden platform measuring 1.2 × 1.0 m. The tanks were filled with 1000 litres, which corresponds to a surface load of 8.2 kN/m 2 . This load is more than half the design pedestrian crowd load of 5 kN/m 2 . However, the structure was also designed for the axle load of a service vehicle with a total load of 80 kN. In terms of bending moment, the proof load caused 55% of the effects of the characteristic standard load for which the panels were designed (23.3 kNm and 42.0 kNm, respectively). The process of filling the tank took about 15 minutes. All measurements were carried out after filling each tank. The filling sequence and their exact location on the structure are shown in Fig. 6, and the view of the set of tanks placed on the structure is shown in Fig. 7.
