The paper considers the joint connection rigidness in a modular building. The joint connection of columns and crossbars with a cross section in the form of square pipes are investigated. The study was carried out by the component finite element method using the IDEA StatiCA software package, the classification of joint connections was adopted according to Eurocode 3. The authors consider two types of joint connections, namely, the ones with an angle stiffener and the ones without an angle stiffener. In the course of research, there were obtained the values of the rotational rigidity of joint connections for various parameters. The boundary characteristics at which joint connections should be considered rigid have been established.
