Abstract

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.

印度巴特那地区地面运动预测

本文介绍了使用响应谱（Rsp）匹配技术MATLAB代码选择和缩放印度比哈尔邦巴特那的地震动，并使用等效线性地震场地响应分析（EERA）excel宏进行土壤放大。包括巴特那在内的比哈尔邦北部属于第四地震区，因此需要采取预防措施，以避免灾难性的地震破坏。巴特那的地震动数据是巴特那经济有效的抗震建筑所必需的。从RspMatch2005技术中获得的五个地震动用于估计巴特那六个选定地点的土壤运动响应。在目前的工作中，生成了巴特那的地震动数据，这是以前文献中没有的。通过SPT试验获得的Patna的插值剪切波速和通过RSP Match软件获得的地震动用作EERA中的输入，以获得放大系数。在地震放大之后，利用当地土壤的特性对地面运动进行了探索。在本研究中，发现在5Hz时放大因子为1.8至5。这种放大的地震动可用于线性和非线性地震结构分析。

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
