Abstract
The 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: Possibility to introduce test results for any type of connection in free form format, irrespective of the type of connection (existent or not); Possibility to deal with any material; Possibility to deal with dynamical tests; Possibility to deal with numerical simulations; Easy interchange (import-export) with any commercial program (EXCEL, ACCESS, etc.); INTERNET on-line implementation. and implemented as independent modules which correspond to different levels of utilisation, as shown in Table 1. An experimental project of beam-to-column composite connection cyclic and dynamic tests currently under execution is presented where both con
