This paper presents a numerical study of the seismic response of seismically isolated buildings when using Hybrid Energy Absorbers at the base of high-rise buildings in terms of their ability to reduce the influence of ground excitation forces. Focus placed on the seismic response for the displacement, story drift, story shear, and acceleration to...
Chapter
Full-text available
The incorporation of base isolation in building construction in the regions of medium to high seismicity is investigated with special emphasis on the geometric nonlinearity response due to the second-order effect. A thorough investigation is carried out by using time history analysis for different building heights located in different seismic desig...

Full-text available
Time-domain spectral matching commonly used to define seismic inputs to dynamic analysis in terms of acceleration time history compatible with a specific target response spectrum is used in this study to investigate the second-order geometric effect of P-delta on the seismic response of base-isolated high-rise buildings. A synthetic time series is...
Thesis
The risk of earthquakes has always been a threat to high-rise buildings. Reducing damage caused by dynamic loads effect is one of the main concerns of structural engineering. At present, various methods have been proven to improve the capacity of structures to withstand earthquake loads. Among these techniques is the base isolation which has proven...

This study aims to investigate the seismic response of high rise base isolated steel buildings with emphases on the effect of the second-order geometric nonlinearity due to P-Delta. To achieve this goal, steel building models with different heights (10 to 30 stories) were analyzed due to various seismic force intensities including moderate earthquake up to strong or very strong earthquake using different procedures including: Modal analysis, equivalent lateral force, Response spectrum, and time history. Several types of base isolators were employed including: FPB, LRB, HDRB, and multiple isolators. A synthetic time history analysis generated by matching target response spectrum in the time domain was used to validate the dynamic response due to various site-specific ground motions. ETABS v18 and ABAQUS 6.13 software have been used for the numerical analyses of all case studies covered in this study.
