Robustness and Energy Absorption Capacity of Laterally Unrestrained Reinforced Concrete Slabs
The structural robustness of buildings is related to their capacity to redistribute loads after a local failure preventing progressive collapse. The energy absorption capacity of structural elements allows estimating both, their static and dynamic load-bearing capacities and therefore is a key parameter for robustness assessments. This paper presents a methodology to calculate the static load-deflection relationship of laterally unrestrained reinforced concrete (RC) slabs by means of three different stages: an elastic stage, a transitional elastic-plastic stage and a membrane action stage. Membrane forces are estimated from the kinematic relationships of the slab and equilibrium considerations. This approach includes different failure criteria in order to estimate the total energy absorption capacity of these slabs.
