- Three new concepts are described: (1) an efficient reinforced concrete material model based on plasticity theory; (2) an analytical solution for the integration along the length of the nonlinear beam deformations; and (3) a distribution of deformation technique which allows the preservation of local nodal building rotations while performing the explicit dynamic analysis at a time step corresponding to the global floor rotations. These developments were implemented into a prototype PC-based computer program. Benchmark analyses were performed to indicate the accuracy and efficiency of the method.
