| dc.description.abstract | Progressive collapse and seismic resistance are separate topics that have many examples in the literature. However, because both of these events occur rarely, there are not many accurate research examples that have been conducted. Life threatening earthquakes occur once in every 50 years in high risk earthquake zones. Inelastic behavior of steel using a simple and reliable approach is an ongoing process. There are some conclusions about using lateral bracing and shear wall but this makes the design and the cost of the structure inaccurate for the contractor as well as limits the architectural designs.
In this project, a time history analysis of a four story moment resisting steel frame will be conducted. For the distribution of the energy released from the ground motion, a strong column-weak beam approach will be used. The structural system and every element in the system will be compact to resist flexure and lateral torsion that occur during the acceleration. Specific columns from the first floor will be removed and the structure will be accelerated under specific earthquake examples.
As a result of this project, an ideal four story steel frame resisting collapse under seismic loading will be obtained. Pros and cons of this method will be explained. This will influence further research development on the related topic. Postponing collapse events or limiting the local failure will save many lives and keep the economy stable. | en |
