Apparently the Siemen's Sports Arena failure[1] was attributed to brittle failure in dowelled slotted-in-plate connections, which is also what they used for the steel-wood interface for this bridge. [1]https://www.researchgate.net/figure/The-Perkolo-bridge-after... >"... An overview of capacity models derived using the yield limit equations and following the European Yield Model (EYM) approach is provided in [20]. Major examples of structures collapse led by brittle failure in dowelled slotted-in-plate connections are the two trusses of the Siemens Sports Arena in Denmark [21] and the truss of the Perkolo bridge in Norway [22]. Uncertainty in the evaluation of connections' deformability is responsible for local damage in connections, and change of force transfer mechanisms compare to those considered in the design. ..." |
