摘要
2016年2月6日我国台湾高雄市美浓地区发生M_S6.7级强地震及多次余震,对台湾南部地区造成严重影响。为了研究台湾美浓地震中框架结构的震害原因,在对台南地区震害调查的基础上,首先,根据新化、草岭、善化、台南市、七股等五个台站的地震动数据,从地面峰值速度、脉冲属性和频谱特性等方面,分析了地震动的主要特征;然后,从整体结构、梁柱构件、填充墙、非结构构件和地基土液化等方面,阐述了其震害特征;最后,结合震害调查工作,从近断层脉冲型地震、地基土液化防治、抗震概念设计及隔震减震技术应用等方面,对建筑抗震设计提出了建议。
The M_S 6. 7 strong earthquake and subsequent aftershocks hit Meinung area in Kaohsiung of China on February 6th,2016,which affected a wide area in southern Taiwan. In order to analyze the seismic damages of reinforced concrete frame structure in Meinung earthquake sequence,the filed survey was taken in southern Taiwan.Firstly based on the ground motion data of five seismometer stations,the main characteristics of the peak ground velocity,pulse properties and Fourier spectra were analyzed respectively. Secondly the characteristics of the seismic damages were analyzed from five aspects,including beam,column,infilled wall,non-structural member and liquefaction of foundation soil. Finally based on the field investigation and seismic damage analysis,some suggestions for the seismic design of buildings were provided from four aspects,including near-fault pulse-like ground motion,the prevention of liquefaction soil,seismic concept design,seismic isolation and shock absorption technology.
