摘要:

以快速组装铝合金抢修塔为研究对象,应用有限元软件ABAQUS建立了抢修塔数值模型,确定了与基本周期对应的谱加速度Sa(T₁)为地震动强度指标、节间位移角ISDR为结构地震需求参数,采用极限状态划分方法建立了抢修塔概率地震需求模型。从美国太平洋地震中心数据库分别选取20条余震、主余震序列地震动记录,采用IDA分析方法得到结构的地震响应,评估了在余震、主余震序列地震动作用下抢修塔的易损性,分析了地震动入射角为0° 和90°时抢修塔的抗震承载力。结果表明:①余震作用下,当地震动入射角为0°时,抢修塔遭遇多遇、基本地震作用下的倒塌概率很低,几乎为0,遭遇罕遇地震时的倒塌概率为43.9%; 当地震动入射角为90°时,抢修塔遭遇多遇、基本及罕遇地震的倒塌概率都很低,几乎为0。②主余震序列地震动作用下,当地震动入射角为0°时,抢修塔遭遇多遇地震、基本地震及罕遇地震时的倒塌概率分别接近于0、2.8%和57.6%; 当地震动入射角为90°时,抢修塔遭遇多遇地震、基本地震时的倒塌概率接近于0,遭遇罕遇地震时的倒塌概率为7.2%。

Abstract:

In this paper,we use the finite element software ABAQUS to establish the numerical model of the rapidly-assembled aluminum alloy repair tower.We set the spectral acceleration Sa(T₁)corresponding to the fundamental period T₁ as the seismic intensity parameter and the inter-segment displacement angle ISDR as the seismic demand parameter of the structure,then establish the Probabilistic Seismic Demand Model(PSDM)of the rapidly-assembled aluminum alloy repair tower by using the Limit State Division method.On this basis,we select 20 groups of ground motion records of the mainshock-aftershock sequences from the U.S.Pacific Earthquake Center(PEER)database.Applying IDA method to these records,we obtain the seismic response of the repair tower.Finally,we evaluate the susceptibility of the repair tower under the action of the aftershocks and the mainshock-aftershock sequences.We analyze the aseismic capacity of the repair tower under the action of the ground motion with 0° incidence angle and 90°incidence angle.The conclusions are as follows:①With regard to the aftershocks,when the ground motions' incidence angle is 0°,the collapse probability of the repair tower under the action of the high-frequent earthquakes or the medium-frequent earthquakes is almost 0; the collapse probability under the action of rare earthquakes is 43.9%.When the ground motions' incidence angle is 90°,the collapse probability of the repair tower under the action of the high-frequent earthquakes or the medium-frequent earthquakes or the rare earthquakes is almost 0.②With regard to the mainshock-aftershock sequences,when the ground motions' incidence angle is 0°,the collapse probability of the repair tower under the action of the high-frequent earthquakes is almost 0; the collapse probability under the action of the medium-frequent earthquakes is 2.8%; the collapse probability under the action of the rare earthquakes is 57.6%.When the ground motions' incidence angle is 90°,the collapse probability of the repair tower under the action of the high-frequent earthquakes or the medium-frequent earthquakes is almost 0; the collapse probability of the repair tower under the action of the rare earthquakes is 7.2%.
