The arenas with great grandstands are the public places where the consequences of failure are very high. For this reason, according to EN 1990, they belong to CC3 class consequences of failure. The reliability class RC3 is associated with the consequences class CC3 and is defined by the reliability index β = 4.3 with probability of failure pf = 8,54*10–6. The distributions of horizontal and shear resistance within glued timber body – bolts will be described depending on material characteristics of glued timber body and bolts components. The paper will present methods of timber structural design belonging to CC3 consequences failure class.
