STRUCTURAL PROPERTY OF H-SHAPED BEAM TO BOX COLUMN CONNECTIONS WITH HIGH-STRENGTH BLIND BOLTS-Tensile behavior of local models of the beam to column connections

Abstract

H-beam to box column connections have been ordinary fabricated by the welding method with interior diaphragms. In this method, there are some problems on their fabrication and structural behaviors, because of the complication regarding the details of the welding connections. In this paper, the bolted H-beam to box column connections with split tees and blind bolts are proposed to solve the above problems. Tensile tests were carried out on local models of the connection to understand their structural behaviors. From the tests, it is confirmed that the stiffness and the strength of the connections without diaphragms are improved by covering the column with L-section steel, expanding the distance of bolts, and increasing column thickness. Also the load-displacement relationships can be approximated by the analysis assuming a square frame for column section on the basis of beam theory.
