砌体的力学性能对识别地震作用下的抗震性能起着重要的作用。由于历史地震准确地表明，非工程砌体建筑是地震中受影响最大的结构形式，因此分析模型应该更具代表性，以捕捉真实的破坏机制。类似的情况也发生在1988年、2011年和2015年的尼泊尔地震中。然而，一项广泛的文献调查指出，尼泊尔砌体建筑的力学特性仍然没有很好地确定，因此需要适当注意改进数值模型。为此，本研究旨在确定尼泊尔新古典主义纪念性砌体建筑的力学特性。本文报告了现场试验、离散元模型分析验证和实验室试验结果。
Mechanical properties of masonry play important role in the identification of seismic behavior during earthquakes. As historical earthquakes precisely note that the non-engineered masonry buildings are the most affected structural forms during earthquakes, analytical models should be more representative to capture the real damage mechanisms. Similar scenario was reflected during the 1988, 2011, and 2015 earthquakes in Nepal. However, an extensive literature survey noted that the mechanical properties of Nepali masonry construction are still not well identified and thus require due attention to improve numerical models. To this end, this study aims to identify the mechanical properties for neoclassical monumental masonry constructions in Nepal. In-situ tests, analytical validation using discrete element modeling, and laboratory test results are reported in this paper.
