Rotational capacity of exposed base plate connections with various configurations of anchor rod sleeves
نویسندگان
چکیده
This paper presents a new approach that can enhance the rotational capacity of exposed base plate connections without degrading initial stiffness or strength standard configuration. By inserting steel sleeve with designated geometry between and anchor rod washer, load path end be interrupted, promoting more ductile response. Exposed various geometries are numerically investigated using validated FE model to demonstrate concept proposed method. It was concluded system substantially enhances column bases. An elastic response consistent is maintained indicating compatible existing codified design approaches modification.

Experimental Study for Strength Capacity of Cold-Formed Steel Joists Connections with Consideration of Various Bolts Arrangements
With growth the construction technologies, Cold-Formed Steel, CFS, sections are widely used in ordinary steel buildings because of some advantages such as light weight, ease of installation, decrease in cost, and increase in speed of operation. Using the bolted connections for CFS joist is one of the best details for steel structures. The main objective of this study is to conduct an experiment...
متن کاملBase plate in bending and anchor bolts in tension
This paper describes the behaviour of the base plate in bending and the anchor bolts in tension, which are the major components of a base plate connection. An analytical model has been derived to predict the component characteristics – the resistance and the stiffness. A description is given of how the behaviour is influenced by contact between the base plate and the concrete surface. The prese...
متن کاملMathematical Modeling of Column-Base Connections under Monotonic Loading
Some considerable damage to steel structures during the Hyogo-ken Nanbu Earthquake occurred. Among them, many exposed-type column bases failed in several consistent patterns, such as brittle base plate fracture, excessive bolt elongation, unexpected early bolt failure, and inferior construction work, etc. The lessons from these phenomena led to the need for improved understanding of column base...
