The SidePlate® connection provides a 100% rigid panel zone at the column and increases the beam section properties for a distance of approximately the beam depth (Db) beyond the face of the column. Refer to the SidePlate® Tech Tips document for a description of the different SidePlate® connection types and general design guidelines. Figure 1 - SidePlate® Bolted connection elevation Figure 2 - SidePlate® Bolted connection section BEFORE YOU BEGIN: It is important to ensure that a "Standard Moment Connection" is applied to all lateral beams before any non-prismatic sections are applied. To remove any RBS or SidePlate® built in features do as follows: Select all moment frame beams > Assign > Frame > Moment Frame Beam Connection Type > Standard Moment Connection > OK. Missing this step can result in inaccurate stiffness and/or stress results. USING NON-PRISMATIC BEAM SECTIONS is the most accurate way of implementing the SidePlate® connection properties in ETABS or SAP. The stiffened SidePlate® section extends from column face to Dim A (shown in Figure 1). This stiffened SidePlate® section, which consists of the physical side plates {A}, cover plates {B} and beam, has an approximate moment of inertia (3) times that of the beam alone for SMF, IMF and OMF applications and (1) times the moment of inertia of the beam for R=3 applications.
