Database for the semi-rigid behaviour of beam-to-column connections in seismic regions

Abstract

Paper Number 120 Full paper on enclosed CD-ROMThe behaviour of steelwork connections has long been recognised as complex. A database of test results for connection behaviour constitutes an essential step towards the development of design methodologies, allowing more researchers to investigate in this field without the financial burden of carrying out experimental work, avoiding being misled by incomplete or incorrect data, and opening the way to design assisted by testing.A database of experimental results for steel and steel-concrete composite connections is presented which encompasses graphical treatment of data, numerical manipulation and statistical treatment of groups of results, allowing easy comparison of connection behaviour. Simplified constitutive models for the hysteretic behaviour of connections are presented and included in the database for comparison and calibration with experimental results.The database SERIWWW was developed according to the following specifications:

Experimental evaluation of extended endplate beam-to-column joints subjected to bending and axial force

“…In this model, each non-linear spring was replaced with two equivalent elastic springs using an energy formulation and a post-limit stability analysis. This analytical model was applied to a welded joint extracted from SERICON II database [16], but the comparison with test results was performed without considering the presence of the axial force.…”

Post-limit stiffness and ductility of end-plate beam-to-column steel joints

“…In order to evaluate realistic values of the post-limit stiffness of the various relevant components, a set of four extended end-plate beam-to-column joints tested by Humer at the University of Innsbruck (1987) were selected from the database of steel joints SERICON II [1].…”

Reliability assessment of the post-limit stiffness and ductility of steel joints

“…In order to illustrate the procedures described above, one joint configuration was chosen from the database SERICON II (Klein 105.011) [11], corresponding to a Fig. 6.…”
