【摘要】 开封延庆观为我国著名道观,具有极大的文化和工程技术价值,延庆观的抬升改造为工程界所关注。结合延庆观的结构特点,探索应用现代建筑隔震原理,从隔震和防水方面考虑在基础和底层间加铺橡胶垫,建立了延庆观的隔震有限元模型和实际结构有限元模型。利用有限元分析软件MIDAS,在Taft Lincoln School地震波作用下,对两种模型的周期、速度、加速度和位移等参数进行了对比分析。结果表明,橡胶垫隔震效果明显,能有效地避免地震对延庆观的破坏及地下水对主体结构的侵蚀。更多还原

【Abstract】 Yanqing Temple in Kaifeng is famous Daoist Temple of China which has great value of culture and engineering technology.The engineering also concern on its lifting and renovating.Combining with the structure charactristic of Yanqing Temple,this paper probes and applies the theory of isolating seidmic wave with modern building.For isolating seidmic wave and preventing water,rubber mat is paved between foudation and 1st floor so we get the isolating earthquake model and reality model.Using finite element analysis software—MIDAS,it compares and analysises the two models with the earthequake period,the speed,the velocity displacement and the acceleretion under Taft Lincoln School wave.The result shows that rubber mat has obviously asseismatic affection and can effectly avoid the damage of seidmic wave,prevent the eroding of water to Yanqing Temple’s main stucture.更多还原
