Abstract
The present invention is directed toward a novel moment resisting connection system, for use, but not limited to, with a pony-truss bridge system. The connection system comprises multi-hollow sections that can be, but are not limited to, extruded aluminum and a joint or node connector that can be casted, milled, forged or made by any other means.
Claims32
A moment transferring assembly, comprising:
- a) a connector node element having a plurality of cavities;
- b) a plurality of framing members for mounting to the connector node element into respective ones of the cavities;
- c) each framing member being generally elongated and having an end portion insertable into a respective cavity;
- d) a mechanical fastener for mounting between the connector node element and the framing member and capable of being fastened to maintain the connector node element and the framing member engaged with one another;
- e) wherein the connector node element includes a channel for receiving therein an elongated load carrying chord;
- f) wherein the mechanical fastener has a tool engaging head located for access by a tool through the channel such that when the elongated load carrying chord is received in the channel removal of the head to separate the framing member from the connector node element is precluded.
