Modelling and calibration of a beam-column joint based on modal data
A procedure to identify the dynamic behaviour of a bolted end-plate beam-column joint, based on modal data, has been developed in this paper. A finite element reference model comprising beams has been built with special emphasis on the modelling of the joints. The most uncertain parameters of the models are updated by minimizing the discrepancies between the analytical and the experimental natural frequencies of the model. The minimization is carried out through a novel stochastic adaptive method using only the values of a defined error function. The updated models were tested using modal tests performed on the specimen according to different boundary conditions and static tests.
There is an assumption often claimed and occasionally demonstrated by software engineering researchers and practitioners, that: The quality of designed software artifacts de-pends on the quality of interactions (collaborations) between members of the design team.Relying on the coordinative artifacts framework, we propose to enrich the existing CoDyMA (Collaborative Dynamics Measurement and Analysis) method with a procedure for assessing the quality of coordination interactions and the quality of coordination artifacts within a development team. First, we give an overview of the current CoDyMA method. Second, we present an overview of the coordinative artifacts framework. Third, we discuss how the assessment of coordination activities and artifacts is currently envisioned in CoDyMA (this discussion is illustrated with a case study). Fourth, we initiate a discussion on how the coordinative artifacts framework could inform the CoDyMA method.
