Evaluation of Earthquake Input Energy Distribution in An RC Building for An Energy-Based Seismic Design Approach


Abstract eng:
Current seismic design codes of buildings are based on acceleration spectra in order to evaluate strength capacity which does not directly account for the influence of the duration of ground motion or the hysteretic behavior characteristic of the building. An energy-based approach to seismic design serves as an alternative index to response quantities like strength or deformation to include the duration-related seismic damage effects. Therefore, energy-based seismic design methodology is an alternative tool for the overall performance analysis of buildings. Once the concept of input energy distribution is well-understood, energy dissipation capacity of moment resisting frames can be increased by providing special detailing in reinforced concrete buildings. This paper aims to examine influences of ground motion characteristics and structural properties on distribution of input energy based on a four-story RC moment resisting frame building using different types of ground motions. For developing an energy-based design approach and assessing damage potential of buildings, distribution of earthquake input energy among energy components: kinetic, elastic strain, hysteretic, and structural damping has been investigated. Based on nonlinear analysis results, distribution of the earthquake-induced energy among floor levels as well as among structural components has been evaluated.
