T = thickness of column web or doubler plate, in d z = depth of the panelzone between beam flanges, in w z = width of panelzone between column flanges, in With some exceptions Equation 7 can be written as t ≥ (d b2t bf) (d c2t cf)/90 (9) Continuity Plates At the connection to a beam, the column flange must beThe panel zone component of a steel connection plays a fundamental role on the global behaviour of a momentresisting frame Whilst the treatment of this component for gravity loads is perfectly

Story Shear The actual demand panel zone shear that occurs can be reduced by the story shear coming into the panel zone This story shear is also an input in the Loading section If there is story shear, then the program calculates an M equiv as the design demand This is a reduced demand based on a reduced panel zone shear due to this storyThe influence of the size of the web panel to the quality of prediction by simplified models were studied by Standig 2 and Brandonisio 3 In reality and in general description of component method the web panel and connections are separated A simplified procedure is offered in EN , which is condensing the shear panel andFig 71, the nominal panel zone shear strength (assuming the factored column axial load, Pu, is less than or equal to 40% of the axial yield strength, or 04Py) is obtained from the LRFD Specification for Structural Steel Buildings (1993) as where Fyw = nominal panel zone yield stress, tp = total thickness of panel zone including doubler plate
An example for the subduction zone setting is the Japan Median Tectonic Line Detachment fault related shear zones can be found in southeastern California, eg the Whipple Mountain Detachment Fault An example of a huge anastomosing shearzone is the Borborema Shear Zone in Brazil With a direct welded wbeam to wcolumn, when I check the box to consider "Seismic provisions" the panel web shear increases dramatically When I assign a bolted flange plate connection to the same beam and column, checking the box to consider "Seismic provisions" causes no change in the panel web shearThe slenderness of the web panel is ̅ ˇ 0,76ˆ ˙˝ ˛˚ (623) The reduction factor χw may be obtained in EN cl 53 The shear buckling resistance of the web panel is ˜, # ˙˝ √%&'((624) The resistance of the frame may be designed according to cl 6261 EN

The panel zone check is used to determine whether or not the column must be reinforced locally (at the panel zone) by a doubler to resist the shear from the moment In the centerline (computer) models typically assumed in design the column will have already been designed for the shear caused by the beam axial loads and for what is referred toAnd t cf=column flange thickness Eq 4 , which is adopted in the 02AISC Seismic Provisions, was used to design the medium panel zone specimens This equation represents the panel zone shear strength when the shear strain reaches four times the shear yield strain Krawinkler 1978 Eq
