The impact of floods can be devastating to buildings, especially in countries and villages in mountainous areas. Based on the flood impact risk analysis results, two methods are suggested by authors to improve the flood impact defense capability of rural buildings in this paper: increasing the strength of the mortar used in masonry structures, as well as adding reinforced concrete (RC) columns and circle beams to masonry structures. The impact of floods on the reinforced masonry structures is simulated numerically, and the failure process, stress, and deformation behaviors of masonry structures are analyzed. Compared to the computational results of normal masonry structures, the advantages of the two methods proposed in this manuscript are studied. Increasing the mortar strength slows the rate of damage to the masonry structure but does not improve the deformation or the failure behaviors. Increasing the mortar strength slightly decreases the first principal stress on the mortar and brick elements but has no effect on the third principal stress. Adding the RC frames not only delays the damage to the building and improves the failure behavior of the masonry structure but also decreases the first and third principle stresses of the brick and mortar elements.

洪水对砌体结构的影响分析及缓解措施

洪水对建筑物的影响可能是毁灭性的，特别是在山区的国家和村庄。基于洪水冲击风险分析结果，作者提出了两种提高农村建筑洪水冲击防御能力的方法：提高砌体结构砂浆强度，以及增加钢筋混凝土（RC）柱和圆形梁到砌体结构。数值模拟了洪水对加筋砌体结构的影响，分析了砌体结构的破坏过程、应力和变形行为。与普通砌体结构的计算结果相比，本文研究了两种方法的优点。增加砂浆强度会减缓砌体结构的损坏速度，但不会改善变形或破坏行为。增加砂浆强度会略微降低砂浆和砖构件的第一主应力，但对第三主应力​​没有影响。添加钢筋混凝土框架不仅可以延缓对建筑物的损坏，改善砌体结构的破坏行为，还可以降低砖和砂浆构件的第一和第三主应力​​。
