Abstract

Modern Russian methods for calculating transport infrastructure objects for progressive collapse have been analysed and classiﬁed. An overview of the methods implemented in the SCAD and LIRA computer systems has been made. The transport infrastructure objects of the frame scheme have been calculated for progressive collapse with the removal of the supporting element. The results of the calculation of the frame scheme, taking into account additional parameters: damping of elements; joint work of the ﬂoor and steel structure elements; physical and geometric nonlinearity have been analysed. Analytical, statistical and mathematical methods were applied.It has been established that the existing software systems have sufﬁcient functionality for calculating transport infrastructure objects in a static, dynamic, linear and non-linear problem setting. The results of calculations performed in different computer systems show different results in dynamic and quasi-static methods.The necessity of adjusting the existing Russian building codes, taking into account the calculation procedures in modern computer systems, is revealed.
