9.12 Steel plate ... stiffeners to increase the bearing capacity of the steel connection. ... The next step for the column base plate connection design is to define the load cases. The user can add more than one load cases by clicking on New.
The most common form of connection is a steel plate cast into the wall to which the steel beams of the floor structure can be connected. Shear studs are usually provided on the back of the plate to resist the vertical reaction from the floor beam. Axial forces in the beam are resisted by reinforcing bars which are generally welded to the plate
design is sensitive to tolerances, which are recapitulated for beam to column connections and base plates in Chapter 8. The worked examples in Chapter 9 demonstrates the application of theory to design of pinned and moment resistant base plates, pinned and moment resistance beam to column connections and the use of ...

In this case the base plate may be designed as follows: (i) Divide the factored column load by the design bearing strength of concrete and find the area of the base plate. Select a convenient width of the base plate. Width of base plate = Depth of the column section + 2 (thickness of gusset plate) + 80 mm to 100 mm.
PRACTICAL DESIGN AND DETAILING OF STEEL COLUMN BASE PLATES 1.0 I NTRODUCTI ON 1.1 Preface Steel column base plates are one of the most ~ndament al parts o f a steel structure, yet the design of base plates is commonly not given the attention that it should by engineers. This results in base plate details that are expensive, difficult to
13/1/2009 · RE: Design of Column top plate WillisV (Structural) 13 Jan 09 11:33 As a side note, before performing any fancy analysis, I would first take a look and see how much of the column below the cap plate aligns with the beam above the cap plate - if that area works in bearing (1.35Fy*this area for ultimate strength) then it doesn't matter how thick the plate is - the force …
16/6/2011 · Typical Column Bearing on Concrete Footing. Note that the base plate is a double cantilever in TWO DIRECTIONS. This means that flexural strength must be checked in both directions when choosing the plate thickness. Selecting Length, B, and Width, N, of the Plate.
beam-to-column connections, prEN1993-1-8 also includes design methods for column bases with end-plate connections, new rules for the interaction of moment and axial force at the connection, new rules for calculating the bearing capacity of slotted holes, welded connections to rectangular tubes and improved serviceability limits for pins.
"Design of Steel Bearing Plates," Engineering Journal, American Institute of Steel Construction, Vol. 7, pp. 37-40. BASE PLATES for columns and bearing plates for beams resting on masonry are details associated with the design of all steel structures. Given the load and allowable bearing pressure, the area of the plate is easily computed.
n = edge distance for a column base plate n’ = column base plate design value n.a. = shorthand for neutral axis N = bearing length on a wide flange steel section = depth of a column base plate P = name for load or axial force vector P a = required axial force (ASD) P c = available axial strength P e1 = Euler buckling strength P r

DESIGN OF AXIALLY LOADED COLUMNS Universal Column (UC) sections have been designed to be most suitable for compression members. They have broad and relatively thick flanges, which avoid the problems of local buckling. The open shape is ideal for economic rolling and facilitates easy beam-to-column connections.
16/6/2011 · A bearing plate designed to transfer loads between two structural elements follow the same principles as discussed in the prior section, however the limit state of bearing on concrete or masonry is not used. Figure 220.127.116.11.1 shows a common case of a column being supported by transfer beam.
