ABSTRACT

Reliable estimation of seismic stability of structures built in seismically active regions is an objective that requires a complex investigation and different types of activities. For historical structures and monuments, this requirement is even more essential, because many of them represent unique heritage structures. In-situ testing of a monument for defining dynamic characteristics and seismic testing of scaled models represent the recommended activities to be considered as mandatory. Shake table testing of a scaled monument model provides valuable information about its seismic stability – weak parts and development of failure mechanism – as well as the crucial points of the structure that should be considered when designing the health monitoring system. This paper presents the results obtained by the shake table testing of scaled models of two historical masonry structures: the Old Bridge in Mostar and the ancient Protiron structure in Split. The monitored seismic response presented herein by the measured accelerations, relative and absolute displacements, and strains, as well as the damage identification during the shake table tests, provided essential information about their seismic stability, failure mechanism, and weak points. The obtained results have been used for verification of the analytical models for these two monuments, while the prospective of the conclusions derived from the tests has a possible implementation in planning their health monitoring system.

可靠地估计在地震活跃区域中建造的结构的地震稳定性是需要复杂调查和不同类型活动的目标。对于历史建筑和古迹，此要求甚至更重要，因为其中许多代表着独特的遗产结构。用于定义动态特性的纪念碑的现场测试和比例模型的地震测试代表了建议的活动，这些活动被认为是强制性的。缩放的纪念碑模型的振动台测试可提供有关其地震稳定性（脆弱部分和破坏机理的发展）的宝贵信息，以及在设计健康监控系统时应考虑的结构关键点。本文介绍了通过振动台测试两种历史性砖石结构的比例模型获得的结果：莫斯塔尔的旧桥和斯普利特的古代Protiron结构。本文中通过测量的加速度，相对和绝对位移，应变以及振动台测试过程中的损坏识别，提供了监视的地震响应，从而提供了有关其地震稳定性，破坏机理和薄弱点的基本信息。获得的结果已用于验证这两个纪念碑的分析模型，而从测试得出的结论的前瞻性可能会在规划其健康监测系统时实现。本文中通过测量的加速度，相对和绝对位移，应变以及振动台测试过程中的损坏识别，提供了监视的地震响应，从而提供了有关其地震稳定性，破坏机理和薄弱点的基本信息。获得的结果已用于验证这两个纪念碑的分析模型，而从测试得出的结论的前瞻性可能会在规划其健康监测系统时实现。本文中通过测量的加速度，相对和绝对位移，应变以及振动台测试过程中的损坏识别，提供了监视的地震响应，从而提供了有关其地震稳定性，破坏机理和薄弱点的基本信息。获得的结果已用于验证这两个纪念碑的分析模型，而从测试得出的结论的前瞻性可能会在规划其健康监测系统时实现。
