Abstract EN
Steel moment resisting frames are a structural system used throughout the world, mainly for their ductility and the speed and ease of their construction.
These buildings are usually designed per procedures based on seismic design codes, seeking to minimize the total cost of the building.
To aid in better building designs, researchers have proposed different methodologies, which have been proven to be effective.
However, their practical use has been limited by their low computational efficiency and their difficulty to implement by practicing engineers.
This article proposes a method to improve the seismic performance of steel moment resisting frame buildings based on eigenfrequency optimization.
The main advantage of the proposed method is its computational efficiency and that it is simple to implement.
The method is demonstrated for a four-story and an eight-story building, whose seismic performance is compared to traditional building designs using nonlinear analyses and seismic fragility functions.
The results show that the seismic performance improves significantly with the proposed method with respect to that of traditionally designed buildings, reducing their seismic fragility and increasing their overstrength.
These findings and the computational efficiency of the method suggest that it is a viable alternative for use within engineering practice.
