Buckling of orthotropic plates with bimoments [PDF]

Инженерно-строительный журнал, 2015
The paper is dedicated to improvement of plate theory in order to take into account forces, moments and bimoments, generated by nonlinear law of displacement distribution in plate cross-sections.

Dynamic methods of spatial calculation of structures based on a plate model [PDF]

E3S Web of Conferences, 2019
This article was devoted to the development of methods of the dynamic calculation based on the finite difference method of laminar structures in the framework of the bimoment theory, which takes into account the spatial stress-strain state.

New Interaction Formulae for Plastic Resistances of Z-Sections under Combinations of Bending Moments M_y,Ed, M_z,Ed and Bimoment B_Ed [PDF]

Buildings, 2023
Exact interaction formulae for the plastic resistances of Z-sections under a combination of three internal forces, i.e., the bending moment about the strong axis My,Ed, bending moment about the weak axis Mz,Ed and bimoment BEd, were created and analyzed.

Behavior of symmetric steel I-sections under combined bending and torsion actions allowing for plastic deformations

Инженерно-строительный журнал, 2014
In steel structures, the combination of both a bending moment and bimoment actions on I-beam members is possible in many cases. In the elastic stage of work, the material bearing capacity check is based on maximum normal stresses, which for symmetric I ...

To the calculation of orthotropic plates taking into account bimoments

Bulletin of the National Technical University "KhPI" A series of "Information and Modeling", 2022
The work is devoted to the development of the bimoment theory and the method for calculating thick plates in the framework of the three-dimensional theory of elasticity. The basic relations and equations of motion of the plate are given, constructed with respect to forces, moments and bimoments, arising from the nonlinearity of the law of distribution ...

Study of longitudinal oscillations of a five-storey building on the basis of plate continuum model [PDF]

E3S Web of Conferences, 2019
Continuum plate model in the form of a cantilever anisotropic plate developed in the framework of the bimoment theory of plates describing seismic oscillations of buildings is proposed in this paper as a dynamic model of a building.

Bimoment equilibrium of finite segments of Hillerborg plate

Magazine of Concrete Research, 1979
Synopsis The term ‘Hillerborg plate’ is used in this paper to distinguish ‘no-torsion or’ ‘torsion-free’ plates, slabs or grillages subject to two-way bending. A wide range ofstructures (‘space deck’ roofs, bridge decks, concrete slabs) can be treated as Hillerborg plates.

Application of superelements in static analysis of thin‐walled structures

Journal of Civil Engineering and Management, 2004
A concept of a beam superelement is suggested as a new tool in the static analysis of structures made of thin‐walled members. This proposal seems to be especially attractive for treating the problems where the existing one‐dimensional models do not ...

NUMERICAL SIMULATION OF BEHAVIOUR OF THIN-WALLED FRAMES SUBJECTED TO STATIC LOADS [PDF]

TASK Quarterly, 2002
In this paper we are discussing the problem of behaviour of frames composed of thinwalled members with bisymmetric open cross section. We present results of computer simulations of behaviour of the frame subjected to torsional loads. The main problem of
