Re: Pinned joint of Concrete Structures

[Subject Prev][Subject Next][Thread Prev][Thread Next]


Pinned concrete joints can be made by bending all the vertical column rebar approximately 45 degrees towards the center so it looks like the end of a pencil.  I have never seen this done before in a structure but I have seen it done for concrete piles into pile cap connections.

        Subject:        Pinned joint of Concrete Structures

How can I make joints of concrete structure into pinned joints in practical?
When I design a concrete structure, I can assume like this one is pinned and
that one is fixed.  However, in the drawings or in practical, the fixed and
pinned joints of concrete are almost same.  Therefore, I may think that the
concept of pinned and fixed joint in concrete structures is unnecessary.  Is
it right?   If it is wrong, how can pinned joints be made or built in
