Popis: |
Local site conditions generate large amplifications as well as spatial variations in the seismic motions that must be accounted for in the earthquake resistant design of structures. The present paper aims to evaluate the influence of complex site effects on the non-linear response of irregular buildings. To achieve this purpose, site dependent ground motions are produced via Boundary Element Method (BEM). An ensemble of nine earthquakes recorded at the outcropping rock are considered as an input at the seismic bed of complex geological profiles, and acceleration time histories at the ground surface are computed. Several complex geological configurations are considered, taking into account the following key parameters: (i) canyon topography, (ii) layering and (iii) material gradient effect. Two 5-storey buildings are considered: a symmetric and an asymmetric in plan building. A series of Nonlinear Time History Analyses are conducted. The results of this study demonstrate that the presence of local site conditions influence the inelastic dynamic response of buildings. |
