Experimental Study On The Action Loading Of Flood On Rural Buildings

Recently, frequent torrential floods cause tremendous casualties and economic losses to the national people in China. In this paper, six 1:6 scale rural building models made of PMMA are tested to research the impact of flood, which will provide the basic data for the flood-resistant design of rural buildings. The impact experiment of flood on buildings is carried on the large wave-current tank. The height of water is 0.6 meter and the distances between the building and floodgate are 3,6 and 9 meters respectively. The impact loading is obtained by the sensor transducer.Based on the experimental results, the effect of different distance, different ratios of holes and different locations of holes on the impact loading of flood are investigated. Results show that the variation of impact loading distributions in the horizontal direction is not obvious but that decrease gradually with the vertical distance from bottom to top in the vertical direction. The impact loading increases with the distance but it is independent of diverse ratio of holes. The bending moment and resultant force increase with the distance, but decrease with the ratio of holes. The different location of holes affects the impact loading.Results show that the variation of flood loading distributions decreases gradually with the vertical distance from bottom to top in the vertical direction. The flood loading in the horizontal direction is different with vary active areas. The effect of different distance on the flow loading of flood is investigated. Results show that the flow loading increases firstly and then decreases with the distance. The flood loading decreases with the ratio of holes on the impact face, but increases on the side. The bending moment and resultant force also increase with the distance, but are not obvious with the ratio of holes on the impact face.
