	Summary:
	This paper presents the finite strip method adapted to the analysis of two-dimensional nonlinear problems of reinforced concrete plate structures. Non-homogenous finite strip, divided into cells along longitudinal direction and layered throughout the thickness, is developed and the interpolation shape functions are evaluated. The concrete is modelled with a biaxial state of stress that acts in the middle plane and includes the following effects: nonlinear stress-strain relationship in compression, compression failure, strength increase in biaxial compression and cracking. The rebar is idealized by smeared biaxial orthotropic steel layer. Nonlinear material behaviour is described by one- and two-dimensional models of concrete and reinforcement using the analytically derived rheological-dynamical viscoelastoplastic constitutive matrix.
