The problem of computational analysis of thin foundation slabs for vibroactive equipment on a soil base is considered. Methods, algorithms, and examples of computations of such structures for loads transmitted from machines with rotating parts in transient and operating modes are given. A numerical–analytical method is used to analyze conditionally infinite slabs. The finite element method and the modal superposition method are used to analyze slabs of finite dimensions. The results show that the use of thin slabs on a soil base for vibroactive equipment offers several advantages and can be used in construction.
