摘要:
我国《古建筑防工业振动技术规范》中规定在对古建筑木结构进行评估时用古建筑木结构顶层柱顶容许水平振动速度作为评估参数，但在实际工程中，顶层柱顶的速度难以测试，而一层或二层等底层柱顶的水平振动速度通常比较容易测试.论文对交通荷载作用下古建筑木结构进行分析，将古建筑木结构简化为剪切悬臂杆模型，利用最小势能原理建立了结构的侧移形状函数，利用形状函数建立了交通荷载作用下古建筑木结构柱顶水平振动速度幅值和各层水平振动速度幅值转换关系；论文通过对光岳楼在地面交通激励作用下进行了现场测试，验证了古建筑木结构柱顶水平速度幅值计算方法，为木建筑木结构的安全性评估提供了快速方法.
Abstract:
According to the national standard, the security assessment of ancient timber structure was evaluated by horizontal vibration velocity of the top column , but it’s difficult to obtain horizontal vibration velocity of the top column . It’s easy to get one or two layers and underlying columns of horizontal vibration velocity. The paper, based on the principle of minimum potential energy, analyzes lateral shape function of ancient timber structure to deduce the conversion methods of vibration velocity between the top and underlying columns of ancient timber structure. Besides, the thesis conducted a live test for Guangyue tower under the action of traffic load and demonstrated the conversion relation about horizontal vibration velocity of top column ,which supplied a immediate method for the security assessment of ancient timber structure.
