connection moment capacity
what is the typical method for analyzing the moment capacity of a connection?
what are you connecting?
you will have to be much more specific about the type of connection you are asking about. firstly, what is the material? and then, what type moment connection are you considering?
if you are designing in steel, you need to establish the moment that is to be transferred from one
the client (a welder) built a patio. here is the connection he built for the post to footing connection. i need to evaluate lateral loads and determine how much moment and shear it can handle.
hire a consultant who knows what he is doing to check the moment capacity.
what whyun said... if you have a sketch like this and still cannot do the design, you should definately not be trying to get help here. your phone book under "engineers, structural" is the right place.
this connection requires a good understanding of timber, steel and at least a reasonable understanding of concrete design. you can't pick up enough here without someone doing this for you, which is not what eng-tips is meant to be...

as well as the above, it's not what i would call a moment connection, assuming a timber post, therefore moment capacity = 0.
moment capability about the axis parallel to the 16" plate direction will be less than the moment capability about the axis in the 6" plate direction. what is the strength of the concrete and how deep is the embedment of the #4 rebar? also what is steel strength, timber strength and bolt strength? how are the plates connected?
civilperson,
the concrete strength is irrelevant, the connection will not work for a moment of any significance.
ridgeline,
as others have noted, this is clearly outside your region of expertise. i would recommend you consuly someone who knows what they are doing, particularly if you are in a seismic zone.
the connection has negligible moment capacity which can not be relied upon. suggest to design a kiker (diagonal brace) to tie the post and the patio edge beams to provide lateral stability.
