Steel Column Cap Plate Design Example

A w10 x 49 column is supported by a concrete pier whose top surface is 19 inches x 19 inches.

Steel column cap plate design example.

Design a base plate given that the column dead load is 100 kips and live load is 150 kips. The design examples provide coverage of all applicable limit states whether or not a. Cap and base or end plate column splices are covered in chapter 6 of the green book. 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.

Example 7 designing the lightest steel column based on given loads effective length and yield stress. 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. Base plate material is a36 steel and concrete compressive strength is 3 ksi. Most engineers will specify a bolted connection between the cap plate and steel beam to comply with osha regulations and for ease of construction and inspection.

Design examples v14 0 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 ansi aisc 360 10 and the 14th edition of the aisc steel construction manual. When a concentrated tensile or compressive force acts on the end of a round or rectangular hss column with a cap plate and the force is in the direction of the hss axis the walls of the hss member could fail in sidewall yielding with consideration of shear lag. Example 5 calculate the design and allowable compressive strength per lrfd and asd using tables from aisc.
