tailieunhanh - Analytical model for predicting membrane actions in RC beam slab structures subjected to penultimate internal column loss scenarios
The potential for progressive collapse of RC buildings can be estimated by column loss scenarios. The loss of either internal or external penultimate columns is among the most critical scenarios since the beam-slab substructures associated with the removed column becomes laterally unrestrained with two discontinuous edges. At large deformations, membrane behaviour of the associated slabs, consisting of a compressive ring of concrete around its perimeter and tensile membrane action in the central region, represents an important line of defence against progressive collapse. | Analytical model for predicting membrane actions in RC beam slab structures subjected to penultimate internal column loss scenarios
