Wood is mostly used as structural element in the manufacturing of wooden trusses. To connect the timber bars, it is necessary to use connectors. Among the types of mechanical connectors used, the present work aims at studying the toothed metal plate (CMD) connections, consisting of two perforated plates with stamped teeth that are attached to both sides of the joint, thus forming a flat connection, i.e., without the need for the bars overlapping. The design of these connections requires, first, a modeling for the transposition of the efforts to the center of gravity of each cutting area, followed by the transposition to the shear lines. The present work has as objective the study and comparison of analytical models for the dimensioning of the shear lines with link modeling in the Midas® computer software.
