Fire resistance of primary beam – secondary beam connections in timber structures
Abstract
Purpose
This paper deals with the fire resistance of primary and secondary beam connections in timber structures.
Design/methodology/approach
This paper describes a series of unloaded and loaded furnace fire tests in different configurations of these types of connectors.
Findings
The main objective is the fire safety design of joist hangers and full thread screws.
Originality/value
Design recommendations are given.
