Adjustable Hanger or Custom Hanger — You Make the Call By Randy Shackelford, P.E.
It would be a lot simpler for designing engineers if structural connections were always for members at right angles to one another. Often, connections have to be designed for supported members that are at a skewed or sloped angle rather than perpendicular to the header. In these cases, the engineer will have to choose between a premanufactured adjustable hanger and a custom hanger. Simpson Strong-Tie offers both options, and this article will discuss the various considerations that may affect a specifier’s choice.
It makes things easy for an engineer when the building being designed is rectangular. This allows you to make the connections between nice perpendicular members, and standard connectors and joist hangers are easy to specify.
But buildings are not always rectangular and connections are not always between perpendicular members. Nonperpendicular members can have a skewed connection, where the supported member is moved side to side from perpendicular; or a sloped connection, where the supported member slopes up or down from a standard horizontal orientation; or a combination of the two.
To help with these situations, Simpson Strong-Tie offers the option of either premanufactured adjustable hangers or custom-manufactured hangers. The choice may depend on the time frame in which the hanger is needed, the load demands that will be placed on the hanger, the cost of the hanger, or all of these.
If the demand load is low or an immediate solution is needed, Simpson Strong-Tie offers several adjustable hangers that can be skewed, sloped, or both in the field. Adjustable hangers are likely to be the most costeffective option if they meet the load requirements of the connection.
Simpson Strong-Tie has recently revamped its offerings of adjustable joist hangers. The older versions of adjustable hangers, known as the LSU and LSSU series, required that the hanger be attached to the carrying member before installation of the carried joist. This required a disruption of the normal installation sequence in the field. Two new models of adjustable joist hangers have been developed that can be installed after the joist is placed on the supporting member.
