Abstract

During an earthquake, structures standing directly side-by-side without joints move separately. When the distance between the structures is large enough and surpasses the relative displacement of the neighbouring structures, analyses can be performed by the common algorithms. However, if relative displacements are larger than gaps available, individual structures will hit each other in various points, i.e. results obtained by the original mechanical model cannot be used. The task is solved by building up the vibration process from phases using the modal analysis. 1 Introduction In large building complexes, individual structural units are separated by expansion gaps, with a size of only several centimetres. Structures erected on a common base in different times may be structurally also partitioned. The impa
