Forecasting ground movement of Patna Region, India
This paper presents the selection and scaling of ground motion of Patna, Bihar (India) using Response Spectra (Rsp) Match technique MATLAB code and soil amplification using Equivalent-linear Earthquake site Response Analyses (EERA) excel macro. North Bihar including Patna is in seismic zone IV hence preventive measure are to be explored to avoid catastrophic earthquake damages. The earthquake ground motion data of Patna is required for economic and effective earthquake resistant constructions in Patna. Five earthquake ground motions obtained from RspMatch2005 technique used to estimate soil movement response for six selected sites in Patna. In present work, the earthquake ground motion data of Patna is generated which is not available earlier in literature. The interpolated shear wave velocity of Patna obtained by SPT test and earthquake ground motion obtained from RSP Match software used as input in EERA to acquire the amplification factor. After that amplification of Earthquake, ground motion using local soil behaviour explored. In present study, it is found the amplification factor is 1.8 to 5 at 5 Hz. This amplified ground motion may be used for linear and nonlinear earthquake structural analysis.
期刊介绍:
The Earthquakes and Structures, An International Journal, focuses on the effects of earthquakes on civil engineering structures. The journal will serve as a powerful repository of technical information and will provide a highimpact publication platform for the global community of researchers in the traditional, as well as emerging, subdisciplines of the broader earthquake engineering field. Specifically, some of the major topics covered by the Journal include: .. characterization of strong ground motions, .. quantification of earthquake demand and structural capacity, .. design of earthquake resistant structures and foundations, .. experimental and computational methods, .. seismic regulations and building codes, .. seismic hazard assessment, .. seismic risk mitigation, .. site effects and soil-structure interaction, .. assessment, repair and strengthening of existing structures, including historic structures and monuments, and .. emerging technologies including passive control technologies, structural monitoring systems, and cyberinfrastructure tools for seismic data management, experimental applications, early warning and response
