Abstract:

Bolted end plate connection was proposed as beam to column rigid connection between H beams with corrugated webs and common H columns. Based on rigid end plate model and T stud method on tensile performance of high strength bolts, a designing method for bolted end plate connections of H beams with corrugated webs was proposed. Then 2 static tests of beam to column bolted end plate connections of beams with corrugated webs were conducted, and finite element analyses(FEA) of the specimens were carried out with the commercial software ABAQUS. The maximum tension in bolts under designing moment from test results and FE analysis were presented, which proved the designing method for high strength bolts to be secure. A comparative study of designing moment with the end plate yielding moment proved the reliability of designing method for end plate.
