| Abstract | Investigations were made to determine the strength and failure characteristics of hangnails, a modern type of timber connector basically used
as connectors for wooden trusses. Basic resistance of nails to withdrawal and lateral loads were studied first to compare the strength performance and failure characteristics of hangnails. Three sizes of common nails were studied for their basic resistance. Two types of hangnails manufactured
in the Philippines were investigated. The two types of hangnails differ mainly in plate thickness, tooth size and spacing, tooth type, and number
of teeth per square inch of connector. Test results showed that the with drawls resistance of nails varies linearly with the depth of penetration and nail diameter, nails have higher withdrawal resistance when driven to side grain and against lateral loads, failure occurs by bearing failure of wood.
The strength of hangnails was governed by the tensile strength of the hangnail plate, the shearing strength of the tooth, and bearing strength-of the
wood member. Three types of failure patterns were observed, namely, breaking of the plate, shearing of the teeth, and bearing failure in the wood. Based on the test results, a recommendation for proper selection and design of hangnail connector s was given. |
