Comparative study of finite element methods of calculation of ribbed reinforced concrete floors
Structural Mechanics of Engineering Constructions and Buildings, 2022 The paper presents the results of a comparative study of several finite element models of ribbed reinforced concrete solid floors. Using the example of a solid slab with infrequent ribs arranged along a grid of columns, three models frequently used in ...

On triply coupled vibrations of axially loaded thin-walled composite beams [PDF]
, 2010 Free vibration of axially loaded thin-walled composite beams with arbitrary lay-ups is presented. This model is based on the classical lamination theory, and accounts for all the structural coupling coming from material anisotropy.
