A blind analysis contest for a full-scale four-story building was announced in 2007 by the executive committee of the E-Defense steel building project, sponsored by the National Research Institute for Earth Science and Disaster Prevention in Japan.
In this contest, each participant should predict the structural response before and after the test was performed using the three-dimensions shaking table located in Miki City, Hyogo Prefecture, Japan.
This work presents the results obtained from dynamic analyses performed on the building using SeismoStruct, a fibre element-based program. Through comparing the results given by the program with experimental ones, the aim of the work was to demonstrate that nonlinear dynamic response of steel buildings is possible.
The influence that some modelling choices (hysteretic rules, mass discretization, damping parameter) have on the prediction of the global structural response were investigated in order to obtain the best representation of the real building.
The final model and analysis have a negligible difference from experimental results validating computer capabilities in predicting nonlinear dynamic response also of steel buildings.
