作为中国文明的重要组成部分，中国古代建筑有一个本土的和独特的建筑体系，从史前时代到现在一直保留着它的主要特征，并将其影响传播到其他国家，如韩国和日本。随着环境侵蚀和时间影响的加剧，这些因素已经降低了它们的结构抵抗力，保护这一建筑遗产已变得势在必行。通过对西安城墙北门前塔的现场测量和模型试验，为西安城墙的研究和保护提供了基本的木结构特征资料。在足尺现场试验中，测量了塔的振动模态。结构的前四个固有频率分别为1.10、1.70、2.73和3.10 Hz。木结构和有机玻璃模型的多点激振试验验证了现场足尺试验得到的第一阶和第二阶振型是塔的振型。通过试验获得了阻尼比、滞回曲线等有价值的数据和信息。
As an important part of the civilization in China, ancient Chinese architecture has an indigenous and unique system of construction that has retained its principal characteristics from prehistoric times to the present and spread its influence to other countries such as Korea and Japan. With the exacerbating environmental encroachment and time impacts that have been reducing their structural resistance, it has become imperative to preserve this architectural heritage. To provide the basic characteristics of the timber structures as fundamental information for research and preservation, on-site measurements and model tests were conducted on the front tower over the North Gate of the Xi' an City Wall. In the full-scale on-site tests, the vibration modes of the tower were measured. The first four natural frequencies of the structure were found to be 1.10, 1.70, 2.73, and 3.10 Hz, respectively. Multipoint excitation tests on wooden and polymethyl methacrylate (Perspex) models validate that the first and second modes obtained by the on-site full-scale test are the vibration modes of the tower. Many other valuable data and information were obtained through the tests, such as the damping ratio and the hysteresis curves.
