Abstract
The application of endurance time method for optimum seismic design of steel moment-resisting frames using the uniform deformation theory
Highlights
The proper seismic design of structures is one of the biggest challenges in building structures with enough strength, stiffness and ductility
Moghaddam and Hajrasouliha [13] showed that using the uniform deformation theory, a structure can be designed for a specific earthquake record which behaves better than the equivalent weight designed structure based on the proposed methods in seismic codes
A new and fast method based on endurance time method analysis combined with the uniform deformation theory was proposed to optimize steel momentresisting frame design
Summary
The proper seismic design of structures is one of the biggest challenges in building structures with enough strength, stiffness and ductility. Hajrasouliha et al [18] suggested an efficient method for optimum design of concrete frames at different seismic hazard levels by combining the performance-based design and the uniform deformation theory They showed that the designed structures suffer less damage during earthquake compared to the same-weight structure designed by IBC-2009 [19]. Asadi and Hajrasouliha [26] proposed a practical method based on the concept of the uniform damage theory, in which the total life-cycle cost is considered as the main objective function for optimum seismic design of concrete frames Their results showed that all predefined performance targets are satisfied and the maximum inter-story drift ratio and total life cycle cost of the frames are reduced. Its results are in good agreement with other conventional seismic analysis
