DESIGN OF GUSSETTED BASE Dr.
. In this example 65508 mm equal leg angle carrying 166 kN of tensile force is connected to the gusset plate by means of 5 mm thick fillet welds. Select a convenient width of the base plate. I Divide the factored column load by the design bearing strength of concrete and find the area of the base plate.
The allowable bending stress in the slab base is 185 Nmm 2 MPa. Axial load of column is 600 kN. In this case the base plate may be designed as follows.
Example 11 Design a base plate for an axial load of 60 kips and a moment of 480 in-kips. Gusseted Welded Base Plate. The recommended procedure to follow is to propose a size of the weld throat and to check whether it complies with the requirement of resistance.
N d 2 3 in B bf 2 3 in 2. Calculated stress distribution in a gusset plate Shedd 1934. Additionally Examples IIC-1 IIC-2 IIC-5 IIC-6 IID-1 and IID-3 all contain calculations for the Whitmore section.
Results for design purposes An example from his book is shown in Figure 9 which shows the calculated stress distribution in a gusset plate with a discontinuous bottom chord member at the panel point of a truss. It is assumed uniformly distributed under the slab. Dimension of gusset plate.

The structural member is an 8-inch wide flange and the base plate is 14x14. N14 A N125 8 60 k 480 in-k T fc 55 C A3 Fig.
To obtain load on reinforcing pl use max normal stress on above section and multply it by gusset thickeness to get line load on reinf pl. The optimum shape design of the gusset plate with welded connection shown in Fig. The design examples provide coverage of all applicable limit states.
A thick steel base plate and two cleat angles connecting the flanges of the column. A Steel column of effective height 5m has to transmit an axial load of 2000KN. So this is how one can design a gusset plate when the column is under compression and moment okay.
Determine plate cantilever dimension m or n in direc- tion of applied moment. Convert brace load into shear and normal forces on this sectionNormal force will also result in a moment on the section. Consider the yielding and fracture of the tension member.
Example 122 A column section SC 250 856 carries an axial load of 600 kN. Truss Gusset Plates and Connections of Truss Members to the Gusset Plates are Ordinarily Stronger than the Truss Members to which they are Connected. Column bases are structural elements used in the design of steel structures to transfer the column load to the footings.
Design Examples V140 AMERICAN INSTITUTE OF STEEL CONSTRUCTION iii PREFACE The primary objective of these design examples is to provide illustrations of the use of the 2010 AISC Specification for Structural Steel Buildings ANSIAISC 360-10 and the 14th Edition of the AISC Steel Construction Manual. Load coming from top to bottom needs to transfer from steel to concrete o. To resist axial forces coming from top to bottom Column Base plates are designed.
Determine the design strength of the tension member and connection system shown below. Choose trial base plate sizes B and N based on geom- etry of column and four-anchor requirements. Fy for the plate and anchor bolts is 36 ksi and fc is 3 ksi.
