steel column cap plate design example

In addition to the examples that demonstrate the use of the AISC Manual tables design examples are provided for connection designs beyond the scope of the tables in the AISC Manual. The use of cover plates in regions of high moment allows the use of a section of lesser weight and lesser flexural capacity to be used as the primary beam.

Select a convenient width of the base plate.

. Therefore from Table 52 of Eurocode 3 section UC 254x254x89 is class 1. End plate beam to column flange connection 150 15. In this case the base plate may be designed as follows.

This may result in a cost savings in some cases. In a 1969 Engineering Journal article Some Non-Conven-tional Cases of Column Design ST.

Base plate - Column with moment 207 REFERENCES 215. For the worst case scenario place a concentrate load beam reaction at the edge of the plate mid way in between column flanges. A W10 X 54 column of A36 steel carries a concentric load of 120 kips.

Example 11 - Design of a Column Base Plate. Typical column cap plate connection without stiffener plates. Column splice - Bearing 170 17.

Consider a 203 203 46 UKC column in simple design in S275 steel subject to the following values of forces and moments. The wing plates must extend beyond the end of the cover plate for a length adequate to develop the load into the column. L b Transverse Plate or.

I have a W section column which has a W section beam pass over top and rest on the top of the column. Detailing requirements design procedures worked examples and. Base plate material is A36 steel and concrete compressive strength is 3 ksi.

Base plate - Nominally pinned 201 20. Bearing plates are used to transfer concentrated compressive forces between two structural elements. When a beam supports are large concentrated load from a supported element such as a column.

Typical beam flange connection with upper column and stiffener plates. F yw F y of HSS Column. DESIGN OF AXIALLY LOADED COLUMNS 20 HISTORICAL REVIEW.

Steel Column Cap Plate Design Steel Column Cap Plate Design PEinVA Structural OP 2 Oct 08 1015. Ct_w dt 2603103 253. In yielding the load is assumed to distribute from the top of cap plate down at a slope of 251 resulting in a dispersed load width of 5t p l b.

Below is a summary of variables to assume in Specification Eq. The foundation concrete has a 28-day specified strength f 3000 psi. Applied to the column members and bolted to the beam or rafter especially cap plate connections in mezzanine floor structures.

Design of Column top plate. The cap plate should be designed for bending. I Divide the factored column load by the design bearing strength of concrete and find the area of the base plate.

A W10 x 49 column is supported by a concrete pier whose top surface is 19 inches x 19 inches. If there is no extreme loads usually I call a plate either equal to the sitting beam flange or slightly thicker. In this video you will learn how to design column cap plate combined connections for beam to column joints.

Which can be fillet welded to the column. Cover plates are plates added to the flanges of beams to increase the flexural capacity of the beam over some portion of the beam. Design a base plate given that the column dead load is 100 kips and live load is 150 kips.

Column splice - Non bearing Net tension 195 19. Fin plate beam to column flange connection 159 16. Design a base plate of A36 steel to occupy the full concrete area.

C b-t w 2r2 2563 10 2 x 1272 22092 1105 mm. Typically this occurs in two conditions. Cap and base or end plate column splices are covered in chapter 6 of the Green Book.

ExampleBase Plate with Concentric Column Load AISC ASD. Width of base plate Depth of the column section 2 thickness of gusset plate 80 mm to 100 mm. When a beam or column is supported by concrete or masonry or.

The moment applied by these eccentric reactions should. KCap plate thickness t p. The design procedures and examples which fol-low the discussions are given first in ASD format and.

Tion on the design of base plates for steel columns. Is the cap plate design to be treated as a base plate design if I dont have stiffeners and if I have stiffeners is it more for constructability. Some of these are described below.

Part subject to bending. The material is taken from reports papers texts and design guides. 6 6 2 1 5 0 2 b 33 Types of Column Sections Steel suppliers manufacture several types of sections each type being most suitable for specific uses.

Example of simple construction. If cap and base plate splices are located away from a point of restraint special consideration should be given to ensuring adequate stiffness so that the member design is not invalidated. Column splice - Non bearing 181 18.

Design compression force N Ed 589 kN. The design examples provide coverage of all applicable limit states whether or not a particular limit state controls the design of the member or connection. Dalal tabulated effective length factors for the stepped column configurations shown in.

The intent is to provide engineers with the re-. T w HSS wall thickness t des. For sections fabricated by plates by welding the Value of fy should be reduced by.
