connection details between crane cap and crane leg - Heavy Industrial Building

[SM3225]

Hello Everyone,

Greetings.

I am new to this community. At the very first want to thank this forum and members for their able contribution in advance.

Could anyone please let me know what's the best suited connection details between crane cap and crane leg?

My column configuration is as stated below -

a. Upper Shaft - Roof supporting column / Roof leg

b. Lower Shaft - Below crane cap consists two "I" sections spaced along the span direction & laced together. In a bit elaborated way one directly below the gantry girder (crane column) and the other one supporting wall cladding .

I was rummaging through CISC design guide - found some go by, but still not found any literature/calculation explicitly addressing this issue.

Please note down the following details

a. Crane capacity = 290t/60t (Heavy duty)

b. No of wheels per end carriage = 4

c. No of end carriages = 2

d. Crane girder span = 24 m

Any specific details advisable to cater for the given scenario - would be of great help to me.

Thanks.

I am not understanding your question. The attachment you gave showed perfectly good details for this type of top-of-column connection for heavy crane loads. Is there something specific about this type of connection that you do not understand?

There is a publication by AISC, "Design of Industrial Buildings". It's one of the best references I know of.
The beam to column connection is one I haven't seen before. Typically the beams just rest on top of the column cap plate.

Agree with thaidavid40. That is an appropriate detail for a very heavy crane as indicated.

Sawbux, this is a different animal than the run of mill bridge crane.

Thanks everyone for their reply -

Specifically I am looking for the following info -

a. Should the end post be designed for crane girder end reaction alone similar to an end baring stiffener? Or else I need to consider something more on it.

b. What's the design philosophy regarding the bearing plates housed on top of cap plate?

Please refer the attachment along with my queries.


Regards.

a. Yes, it is a bearing stiffener. Design as a column.

b. Those are not bearing plates. They are for alignment, and only need to resist the lateral forces of the crane.
