ABSTRACT
Two typologies of planar reinforced concrete structures - frames and shear walls were analyzed. The determination of the parameters having the highest influence on the structural response (the so-called "Screening Design") was performed using Fractional Factorial and Plackett-Burman Designs of Experiments. These two types of experimental designs were chosen taking into consideration a large number of parameters during the analyses. One target is obtaining a reasonable number of combinations of the parameters so that it would result an equal number of structural models. The influence of each structural parameter on the structural response will be determined using a first order linear regression model. The results indicate that the distinct behavior of reinforced concrete frames in comparison with reinforced concrete shear walls is the result of the influence of different structural parameters on their seismic response.
