Numerical prediction of the response of a squat shear wall subjected to monotonic loading

In this paper, the behaviour of a squat shear wall is investigated. The study fits into the experimental programme driven by CEOS.fr on modelling of the behaviour of reinforced concrete (RC) structures subjected to monotonic and cyclic loading. The shear wall has been analysed through non-linear finite element (NLFE) analyses and analytical procedures, and the results obtained were compared with the experimental results. The design shear resistance of the wall has been evaluated with analytical and numerical procedures following the prescriptions of the new Model Code 2010, according to which the resistance of RC structures can be assessed through standard analytical procedures and from the results obtained with NLFE analyses applying three different safety format methods. In order to validate the structural assessment obtained with numerical procedures, the analyses have been carried out using two different finite element codes: the total strain crack model implemented in the finite element code DIANA and the constitutive model Physical Approach for Reinforced-Concrete under Cyclic Loading implemented in a user subroutine in ABAQUS code.
