Multi‐Axial Concrete Behaviour
Although uniaxial material laws are extremely powerful for many problems of structural analysis they reach their limits regarding plates beyond strut‐and‐tie models, and furthermore regarding slabs and shells. An immediate transition from uniaxial to triaxial models is appropriate and biaxial behavior is derived as a special case from 3D. Regarding common construction materials – concrete, steel, wood and glass – the behavior of concrete reveals to be most complex. Thus, this chapter summarizes the essential aspects of multiaxial concrete behavior within the context of continuum mechanics. Multiaxial stress‐strain relations are initially considered separated from multiaxial concrete strength conditions. A number of formats like elasticity, elastoplasticity, damage, damaged elastoplasticty and microplane are specified which merge strength and nonlinear stress‐strain behaviour in a consistent way.
