The attenuation of seismic waves reflects the elastic nature of the media within which the waves propagate. In this study, we calculate the Coda-Q(Q_c), frequency dependence(η), Vp/Vs and Poisson's(υ) ratios by using 2621 vertical component seismograms generated by 987 earthquakes recorded by 13 seismic stations in Eastern Anatolia, and creat a 2-D seismic tomographic Q_c model for the region. The obtained model provides significant information for exploring the boundaries of adjacent tectonic units within the upper crust and interpreting their dynamic characteristics. The 2-D Q_c model and the other parameters are consistent with the seismotectonic features of Eastern Anatolia. Highly heterogeneous Q_c values are observed in the study area dividing it into north-south directed bands of low and high attenuation. The highest η values were obtained beneath the northwestern and eastern parts of the study region. Clear, high and low υ values are obtained in the western and eastern parts of the study area, respectively. The spatial variations in the measured parameters are consistent with many geophysical observations including low Pn velocities, efficient Sn blockage, high heat flow, and widespread volcanism. Different upper crustal thicknesses and inhomogeneous stress distribution along the East and North Anatolian Fault Zones may also contribute to the observed heterogeneities. 相似文献

In the hilly region due to scarcity of the plain area, buildings like set back-step back are more often used and also as a big surge in the telecommunication industries, rooftop tower adaptation is very common story nowadays. In the present study an analogy has been drawn to find out the influence of the rooftop telecommunication tower on the setback-step back building resting on ground at 20° and 30° slopes. A dynamic analysis has been performed and compared on the 4 legged angled section telecommunication tower which is located on the roof top of set back-step back building by varying positions of tower with the existing host structure built up on ground slope of 20° and 30° in both directions(X and Y). 相似文献

弹塑性时程分析一般用来评估和验算结构抗震性能,如何选取合适的输入地震动是其中关键工作之一。为给结构弹塑性时程分析选取地震动提供合理的参考参数,本文讨论了地震动反应谱参数与结构地震响应之间的相关性。首先建立了6层和7层两个钢筋混凝土(RC)框架结构数值模型,分别对两个结构进行了大量地震动作用下的时程反应分析,并考察了地震反应特点;然后将结构地震响应与地震动反应谱参数建立关系并进行了相关性分析。结果表明:对RC框架而言,结构地震响应与弹性谱参数相关性较小,与等强度反应谱相关性随标准屈服强度降低而增大,与等延性反应谱相关性随延性增大而增大,而与地震动输入能量谱在标准屈服强度较小时相关性最大。建议RC框架结构在进行地震反应时程分析时,可以参考地震动的弹塑性输入能量谱、等强度速度谱和等延性加速度或位移谱,以选取引起结构不同地震反应水平的输入地震动。本文结果和结论可供结构弹塑性时程分析选取合适的输入地震动参考。 相似文献

为了确定框架结构弹塑性时程分析时输入地震动记录的调幅方法,本文利用一个1/40比例的框架结构振动台试验研究了四种地震动记录调幅方法的适用性。利用四种地震动记录调幅方法对20条地震动记录调幅,通过振动台依次输入不同周期的框架结构中,通过分析结构顶层的层间位移角和最大加速度两个参数的变异系数,确定最适宜此种结构体系的地震动记录调幅方法。研究表明,当结构的基本周期可以准确确定时,利用S_a(T_1)调幅方法得到的地震动记录引起结构响应的离散程度最小;当结构的基本周期不确定时,利用MIV调幅方法得到的地震动记录引起结构响应的离散程度最小;当周期有30%的变化时,ASCE调幅方法引起结构的最大加速度的变异系数波动不大,相对比较稳定;无论何时PGA调幅方法得到的变异系数都是最大,表明此法得到的离散程度最大。建议在对框架结构进行时程分析时,对于确定性周期的结构采用S_a(T_1)调幅方法,对于不确定性周期的结构采用MIV调幅方法,ASCE和PGA调幅方法不宜采用。 相似文献

剪切波速被认为是砾性土液化判别的有效指标,为探究砾性土剪切波速的影响因素,设计四因素三水准试验,利用GDS大型三轴-剪切波速设备研究含砾量、相对密度、固结应力和应力比等因素对砾性土剪切波速的影响。试验结果表明:砾性土的剪切波速与前述因素都有较好的相关性;当含砾量、相对密度、固结应力、应力比等增大,砾性土的剪切波速也随之增大;四个因素对砾性土剪切波速的影响程度与模式存在差异,其中固结应力是最为显著的影响因素。 相似文献

为了分析一次性爆破拆除多栋建筑造成的地面振动的特征及对周边建筑物的影响,对武汉交通学校群楼爆破拆除中的地面振动进行了测量,并对实测的塌落振动的峰值、频谱特性进行分析。结果表明:此次监测记录到的峰值频率在5～10 Hz,对比高架桥以及单一高层结构爆破拆除数据,倒塌叠加使得振动能量在频谱上分布更加离散,其峰值频率与周边结构自振频率相差变大,周边建筑共振的危险性降低;对于周围的结构而言,水平振动持时大于竖向振动,但水平振动幅值明显小于竖向振动;爆破塌落振动的竖向分量对周围结构的威胁较大,应采取有效的缓冲及隔振措施;由《爆破安全规程》和周边建筑爆破前后主振频率分析可知,本次爆破拆除工作未对周边建筑造成破坏性影响,验证了群楼爆破拆除方案的高效性和安全性。 相似文献
