X-ONE X-PLATE X-SEAL STRUCTURAL ENGINEERING The aim of this section is to provide the resistance specifications for X-PLATE connection plates. The plates, of varying thickness according to the type, are all made of S355JR steel, CE marked according to EN1090 in EXC2 execution class. Each plate has been designed and verified by applying the maximum stresses transmitted by the X-ONE connector, according to three classes of strengths (1): 1. OVERALL STRENGTHS OF THE PLATE (with FEM analysis): shear; pure traction; pure compression; buckling stress or flexural stress. 2. LOCAL STRENGTHS: shear strength of the bolt (EN 1993-1-8 §3.6.1); bearing strength of the plate (EN 1993-1-8 §3.6.1); block tearing strength of the plate (EN 1993-1-8 §8.10.2); strength of the welds. 3. FASTENING STRENGTH ON THE FOUNDATION SUPPORT X-PLATE BASE PLATES The XPLATE BASE plates can be used under the following conditions: use of vinyl ester chemical anchor and 20 mm diameter threaded rod - steel strength grade 8.8 minimum strength class for C25/30 concrete X-PLATE BMINI and BMAXI plates fully restore the resistance of the X-ONE connector. X-PLATE BMINIL/R and BMAXIL/R plates partially restore the resistance of the X-ONE connector. This aspect is illustrated by the resistance domains shown below (2).

(2) The domains are shown according to the reference system for the X-ONE connector. To refer to the reference system for the X-PLATE plates, by applying forces on the X-PLATE plates that are equal and opposite to those applied on the X-ONE connector, these domains must be mirrored with respect to the bisector of the first quadrant. 48 X-PLATE
