Damage-Based Probabilistic Seismic Assessment of RC Frames
A conceptual framework for the probabilistic performance-based seismic assessment of building structures that considers both model uncertainty and response sensitivity to ground motion modification is presented in this paper. A new damage model is proposed for the assessment of building performance to seismic loads. The model is derived at the material level and combined at the element, story a...

متن کاملEffect of Seismic Pounding on Adjacent Blocks of Unsymmetrical Buildings Considering Soil-Structure Interaction
During earthquake buildings which are closely spaced vibrate out of phase if there is insufficient distance between two adjacent building to accommodate maximum lateral displacement, they collide with each other this phenomenon is called as pounding. Pounding leads to verse damages to structure as the responses are drastically increased in terms of base shear, absolute acceleration, impact forc...
متن کاملSeismic Damage Assessment of RC Buildings Subjected to the Rotational Ground Motion Records Considering Soil-Structure Interaction
The significance of the seismic rotational components have been overlooked in the seismic evaluation of structural behavior. As researchers have measured seismic components more accurately using sensitive rotational velocity sensor, it was observed that the magnitude of rotational components is considerable and could not be neglected. Hence, some parts of seismic damage or failure of structures...
متن کاملSeparation between Adjacent Nonlinear Structures for Prevention of Seismic Pounding
Four existing methods to calculate critical separation distances between adjacent nonlinear hysteretic structures are evaluated through Monte-Carlo simulations, for which seismic excitation is characterized as a nonstationary random process. All the methods use the well-known Double Difference Combination rule, but follow different approaches to calculate the correlation coefficient ρ. Results ...
