The material is taken from reports papers texts and design guides.

Steel column base plate design. The intent is to provide engineers with the re search bac kground and an understanding of the behavior of base plates and then to present information and. This information must be read or used in conjunction with can csa s16 01 limit states design of steel structures and the cisc handbook of steel construction 9th ed. A factored load on the column design bearing strength of concrete. The bolts are cast into the concrete base in location tubes or cones and are fitted with anchor plates to prevent pull out.

Tion on the design of base plates for steel columns. The plan dimensions of the slab base plate may now be selected to provide the above area and also so that the projections a and b beyond the rectangle circumscribing the column area nearly equal fig. This results in base plate details that are expensive difficult to fabricate and may even contribute to the hazards. Steel column base plates are one of the most ndamental parts of a steel structure yet the design of base plates is commonly not given the attention that it should by engineers.

Where ƒ ck characteristic strength of concrete. Design of column base plates typical column bases as shown below consist of a single plate fillet welded to the end of the column and attached to the foundation with four holding down bolts. Of the column base plate connection in the elastic and plastic ranges and for seismic loading possibly even the cyclic force deformation relations. Design bearing strength of concrete 0 45 ƒ ck.
