A Review of Simplified Numerical Beam-like Models of Multi-Storey Framed Buildings

Modern computational techniques have greatly influenced the numerical analyses of structures, not only in terms calculation speed, but also procedural approach. In particular, great importance has been given to structural modelling, that is, process by which a structure and actions it is subjected are reduced simplified scheme. The use scheme necessary since structures are, general, considerably complex physical systems whose behaviour large number variables. definition at same time simple enough be easily computable as well sufficiently reliable reproducing main characteristics analysed therefore, crucial task. with reference multi-storey framed buildings, extensive three-dimensional finite element models (FEM) made recent decades researchers engineers. However, an interesting alternative research field concerns possibility studying buildings through equivalent beam-like degrees freedom required effort respect more demanding FEM models. Several proposed single or coupled continuous beams simulate either static dynamic response assuming elastic inelastic constitutive material. this paper, review several scientific papers proposing for presented. Considerations about limits potentialities these included.
