Type: conference-paper
Abstract: This paper discusses problems related to mechanical behaviour of inter-module connections in modular buildings.A specific solution is analysed here.The aim is to collect data about the response of a newly developed inter-module connector and also to create a valid computational model of this structure.Experimental tests are done on medium-scale specimens made of concrete and the connector.A novel test stand has been devised for this purpose and is shown.Digital Image Correlation is involved to study development of cracks observed during the tests.This is followed by numerical static analysis.Appropriate finite element model, enabling description of the nonlinear response of the structure with cracking is searched for with the aid of model updating process.The final model resembles the whole test stand and involves nonlinear concrete damage plasticity material law.Good correlation between the experiments and the numerical estimations is achieved.Thus, the behaviour of the inter-module connection is well determined, while the developed model can be used to analyse the response of a single unit or the whole modular building
