Abstract:
The response of concrete up to complete failure in tension is represented in the load deformation relation. The characteristic parameters are the ultimate strength, stiffness in the ascending branch and the fracture energy. All these parameters depend on concrete composition and environmental conditions, as discussed in the previous chapters. The observed response of concrete at macro-level is determined by the damage initiation and damage accumulation mechanisms at meso- and micro-scale levels. The failure process is governed by (i) the stress ...
