| 摘 要： | 2019年6月17日宜宾双河发生M6.0级地震，造成了距离震中仅5km的双河文庙建筑东北侧上檐翼角损坏和西侧局部斜撑脱落等局部损坏。双河文庙是典型的木结构文保历史建筑，开展相关震害和抗震分析具有重要意义。以近期在周边建立的场地-建筑强震反应融合监测台站获取的强震记录作为类比输入，进行结构地震反应仿真分析，结果表明：该木结构的整体刚度偏小，易发生扭转破坏，在7度中震和大震作用时，结构扭转效效极易引发挑檐处榫卯节点破坏，与实际震害情况吻合，该类结构宜适度补强纵向抗侧刚度，增强整体抗扭能力。

| Abstract: | M6.0 earthquake occurred at Shuanghe town on June 17,2019. Confucious Temple is a typical historical timber architecture, located in Shuanghe town which is only 5km away from the epicenter of M6.0 earthquake. Eaves on wing corner of northeast side and bracing of west side were found to be partially damaged. After the earthquake, Confucious Temple was repaired with retrofitting. The structural model of Confucious Temple was established for calculation and analysis. It is found that the whole stiffness is not strong and easily excited with torsion. Using the strong earthquake record of the structure-ground seismological array which is recently established nearby, the structural damage caused by Shuanghe Earthquake is recurred. The structural analysis under fortification intensity 7 is done. It can be proved that torsional damage is easily occurred in the timber structure. And the mortise-tenon joints are easily damaged under the function of the vertical vibration and the horizontal vibration. |
