If no visible break of the sample occurred within the first check, the height of the drop weight was gradually increased until the sample failed. This procedure parallels the Hatt-Turner Test where the height of drop weight is increased stepwise until failure occurs. In the case of failure within the first check, the height of the drop weight was decreased gradually until the sample material withstood the impact. In accordance to the drop weight test, the shock resistance was calculated based on the highest impact energy withstood by the sample without failure. The impact velocity v1 was calculated in accordance to Equation .

The shock resistance of large-sized LBL samples was determined to be 154 kJ m-2 and 138 kJ m-2 for real-sized samples. These values fit well to measurements ofsmallsamplesin accordance to DIN 52189 (136 (± 18) kJ m-2) (cf. Chapter 5). The shock resistance of large-sized azobé samples was determined to be 115 kJ m-2 and fit into the range ofshock resistance given by Sell for small-sized samples of 90 to 150 kJ m-2 (1997). For large-sized opepe samples, the shock resistance was determined to be 66 kJ m-2 and 38 kJ m-2 for real-sized samples. These values fit into the range of shock resistance given in literature (30 to 40 kJ m-2) by Sell (1997) as well. These results show that the shock resistance determined on small clear specimens of timber may provide guidance when the kick resistance of horse stable infill planks is to be estimated and particularly when looking for alternative wood species. Further on, the data obtained may be used to calculate the required (minimal) dimensions of infill planksto withstand a horse kick of 350 Joule, which was cited as responsible impact load by von Wachenfeldt et al. (2011) (see Chapter . The minimal thickness(width) to withstand a horse kick can be obtained when solving Eq. for A, inserting the responsible impact load and the wood species´ specific shock resistance into the formula, and, subsequently, dividing A (minimal crosssection areas) by the typically provided width (thickness) of infill plank made of, e. g., LBL, azobé or opepe. The results obtained here (Table 1) show that infill planks made of LBL and azobé are kick resistant at their typically provided width (resp. thickness). Width (resp. thickness) could be decreased while kick resistance is maintained. Focusing on infill planks of stable front sides, the cross section of the planks is reduced due to the milling of air slots. Taking this reduction of cross section into consideration, planks made of LBL (130 mm) and azobé (97 mm) are further able to withstand a horse kick of 350 Joule. For planks made of opepe, a kick resistant width was calculated at 250 mm. Thisindicates that a single plank made of opepe cannot withstand a horse kick of 350 Joule. However, a firm bond of tongue and groove connected planks may be able to do this and has to be tested within further investigations. Tongue and groove connections cannot be applied in the case of planks with air slots (door fillings). A possible solution could be to equip the steel frame construction with horizontal metal rods upon which the planks are slid on.
