130 130  It is only available for maximum type results, the maximum criteria are the same as for the point based detailed result, except one significant difference: in this case the searching is not limited to a node, the program checks all node on the shell according to the selected criteria. For the first criteria group (All components maximum) the five stress component maximums may arise at five different nodes on the shell (also possibly from five different combinations), this result is excellent to see the overall maximum stresses on the shell considering simultaneously all nodes and all combinations. These nodes are displayed with position and node number on the geometry figure. In case of the second (All layer maximum by stress type) and third (Layer maximum by stress type) maximum criteria group the search focuses on one stress component, thus all stress figures display the result of the same node that provides the maximum for the selected component with simultaneous stress figures at this node for the other components. In the display options the scale/size of the figures and display/font of the values can be specified.

137 137  The first group of design formulas are the well-known stress checks from the Eurocode, extended to CLT panels: tension/compression and bending in both grain and perpendicular to grain direction, transverse shear stresses and rolling shear. The extension means that these checks are performed layer by layer (in the current layer's local system), at top and bottom or at parabola maximum in case of transverse shear stresses. The second group are three interaction formulas: shear interaction and tension/compression and shear. As these are not included in the EC5, in the calculation parameter of the CLT panel it can be specified that these checks should be considered during the design calculation or not. The third group are the buckling and torsional check. The shell buckling check of CLT panels are performed only for those buckling regions, which has non-zero buckling factor, also for those layers, which are less than 45° from the buckling direction. For the torsional check, typically applied for walls (in plane loaded structures), the "no glue at narrow sides" option must be checked in the application data. These methods are based on different standards and scientific papers, further information about the detailed checking process can be found in the theory manual of this feature: Theory of Laminated Composite Shells - CLT application. In the detailed result of the CLT panel the performed design calculations together with a geometry figure showing the critical nodes are displayed.
