Correlation between ground motion intensity measures and seismic damage of 3D R/C buildings

Seismic collapse risk assessment of super high‐rise buildings considering modeling uncertainty: A case study

“…With respect to the study of the correlation between the ground motion IM and the structural response, Lucchini et al [46] and Kostinakis et al [47] studied the complex process of using a single value to characterize the IMs corresponding to the horizontal components with two-dimensional or three-dimensional ground motion inputting. Based on the analysis results of Scheme 1 in the MSA method, the influence of the four different characterization methods on the aleatory randomness is investigated with the PGA selected as the IM.…”

“…Based on the analysis results of Scheme 1 in the MSA method, the influence of the four different characterization methods on the aleatory randomness is investigated with the PGA selected as the IM. The four characterization methods are as follows [47] When using different characterization methods, each ground motion has a different IM level. In such a situation, to make the collapse fragility curves in Figure 5, n j in Equation (9) is set to 1 and the probability of collapse is set to 1 when θ max is larger than 0.01.…”

The Effect of High-Rise Building Features on Their State under the Horizontal Seismic Loads

“…The complex seismic isolation system and system of seismic dumping will make it possible to use buildings even after the earthquake, providing the simultaneous checking and repair of the structures' components. Only a few research works related to the high-rise building stiffness [15][16][17][18][19] are known and should be mentioned. The analysis of systems of the passive and active earthquake protections are presented in the first one and also requirements for the systems of high-rise buildings earthquakes passive compensation, the one's own original system of the kinematic earthquake dumper is proposed either.…”

Un enfoque alternativo para tomar en cuenta el efecto de la direccionalidad sísmica.

“…The second approach studies the variation of the seismic performance of a building depending on the orientation that it has respect to the applied ground motion record. Recent research has shown that the maximum ductility demand in the displacement of an elastoplastic system with a single-degree-of-freedom (García-Soto et al, 2012), and the maximum displacement response and expected damage of a specific building (Vargas et al, 2012;Kostinakis et al, 2015;Reyes-Salazar et al, 2016;Kostinakis and Morfidis, 2017), can be presented for a different angle of incidence. This shows that the effect of directionality also has an influence on the structural response of a building.…”
