Özet

The seismic performance of a masonry irregular plan-shaped building was determined according to the applicable seismic codes. The strengthened state of the building was considered in the analyses. A finite element model of the examined building was prepared using 3D “Solid” elements. The DAMAGE TC3D plastic material model was employed to simulate masonry member behaviors. Springs compatible with the soil investigation report data were defined to represent the foundation-soil interaction in the shallow foundations. Soil and related earthquake parameters were acquired through drilling and Multichannel Analysis of Surface Waves (MASW) studies. Subsequently, horizontal elastic design spectra were obtained for DD-2 and DD-3 earthquake ground motion levels. The building model was subjected to linear mode coupling analysis. The model was examined for three different earthquake ground motion levels/performance targets. However, the building was found to meet only the “Pre-Collapse" performance target for the DD-3 earthquake ground motion level. Analysis results indicated that the shallow foundations have sufficient soil bearing strength under static and dynamic effects.
