摘要:
以一典型的30 m高薄壁单管通信塔为研究对象,从太平洋地震工程研究中心(PEER)地震动数据中心选取50条近断层脉冲型地震动组成脉冲型地震动集。选取幅值参数、频谱参数、持时参数和能量参数4大类共14个地震动强度参数进行对比分析,从有效性和充分性两个维度得到在脉冲型地震动作用下最优地震动强度参数。结果表明:在同时考虑有效性和充分性的前提下,对于薄壁式单管通信塔,在脉冲型地震动作用下,地震动强度参数最优的是结构基本周期对应的谱加速度Sa(T1)和有效峰值加速度EPA。该结论可为薄壁式单管塔动力时程分析时选择最优地震动强度参数提供理论依据。
Abstract:
The monopole communication tower is one of the main forms of the mobile communication tower.In this study,a typical 30-meter high monopole communication tower was taken as an example,and 50 pieces of near-fault,pulse-like ground motions were selected from the PEER Ground Motion Data Center to form a pulse-like ground motion set.A total of 14 ground motion parameters including amplitude parameters,spectrum parameters,duration parameters and energy parameters were selected for comparative analysis.The optimal ground motion intensity parameters of the monopole communication tower by the action of the pulse-like ground motion were selected in view of the effectiveness and sufficiency of the parameters.The results show that on the premise of effectiveness and sufficiency,for the monopole communication tower,the optimal intensity parameters are the spectral acceleration Sa(T1) corresponding to the basic period of the tower and the effective peak acceleration EPA.
