Applicability of the non-linear wall models

Structural walls are common structural system in low- to medium rise buildings. Their response to earthquakes is usually favorable, but research of their seismic response has been rather limited that is manifested in a design practice. Contemporary codes allow use of nonlinear analysis for design of new buildings and evaluation of the existing ones. While nonlinear analysis is being used as standard tool for seismic design or evaluation there is a problem in modeling the nonlinear behavior of the wall structures. In this paper we have tried to provide an unbiased comparison of the results, if used by an average engineer, obtained by two different analytical approaches, three different computer codes and four different numerical models using standard values. The calculated responses are evaluated against the experimental results obtained during two European large-scale RC cantilever wall tests
