Seismic collapse capacity spectra for simple structures vulnerable to dynamic instabilities

refined analytical collapse capacity spectra

recently, two of the authors have introduced the collapse capacity spectrummethodology, which allows the assessment of the collapse capacity of highly inelastic p-deltasensitive regular frame structures without performing non-linear time-history analyses. the mainingredient of this method is the collapse capacity spectrum, which represents the seismic collapsecapacity of an inelastic non-deteri...

APPLICATION OF NEURAL NETWORK IN EVALUATION OF SEISMIC CAPACITY FOR STEEL STRUCTURES UNDER CRITICAL SUCCESSIVE EARTHQUAKES

Depending on the tectonic activities, most buildings subject to multiple earthquakes, while a single design earthquake is suggested in most seismic design codes. Perhaps, the lack of easy assessment to second shock information and sometimes use of inappropriate methods in estimating these features cause successive earthquakes mainly were ignored in the analysis procedure. In order to overcome t...

Energy-based Seismic Collapse Risk Assessment of Structures

Structural collapse is traditionally associated with the exceedance of a target value of inter-story drift or plastic hinge rotation at structural components. However, such an approach may not accurately estimate the structural collapse potential due to load redistribution and variation of structural damage within the structure. Moreover, collapse prediction may be sensitive to such assumed thr...
