BEHAVIOUR OF SEMI-RIGID COMPOSITE BEAM - COLUMN CONNECTIONS WITH STEEL BEAMS AND PRECAST HOLLOW CORE SLABS

摘要

This paper is concerned with the behaviour of beam - column connections of steel -concrete composite beams with precast hollow core slabs. Experiments were carried out to investigate the joint rotation characteristics and ultimate moment capacity of these connections. Details of the test specimens, instrumentation, test set-up and test procedures are described. Results obtained for the connection moment capacity, rotation capacity and failure modes are presented. It is found that through proper design and detailing, these simple steel connections display the characteristics of a semi-rigid connection with very little extra cost.
