In particular, fast-moving large boulders carried by debris-induced destructive impact loading can strike objects without warning. To resist impact loading caused by rocks in debris, this paper proposed an innovative grid-type debris dam (or Sabo dam) design composed of symmetrical cross-sections of steel tubular flange beams and columns. This paper studied the dynamic performance of the tubular flange columns under impact loading by conducting lab tests and numerical simulations. Moreover, the dynamic response of the grid-type debris dam was simulated under various loading conditions. Comparing three different types of columns with similar configurations under the same loading condition, the tubular flange column proposed in this research exhibits better performance in overall strain, displacement, acceleration, and bending conditions. Furthermore, the results also prove that the proposed structure has excellent interoperability and energy absorption capabilities. When increasing the testing impact load, the failure modes of the dam change from dent at the impact point to local buckling and total failure of the structure, which indicates that the structure has superior performance under impact loading.<\/jats:p>","DOI":"10.3390\/sym14071486","type":"journal-article","created":{"date-parts":[[2022,7,21]],"date-time":"2022-07-21T03:34:40Z","timestamp":1658374480000},"page":"1486","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Experimental Study on Dynamic Performance of Tubular Flange Grid-Type Dam under Impact Load"],"prefix":"10.3390","volume":"14","author":[{"given":"Xiu-Li","family":"Wang","sequence":"first","affiliation":[{"name":"Shock and Vibration of Engineering Materials and Structures Key Laboratory of Sichuan Province, Southwest University of Science and Technology, Mianyang 621010, China"},{"name":"Western Center of Disaster Mitigation in Civil Engineering of Ministry of Education, School of Civil Engineering, Lanzhou University of Technology, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong","family":"Yao","sequence":"additional","affiliation":[{"name":"Shock and Vibration of Engineering Materials and Structures Key Laboratory of Sichuan Province, Southwest University of Science and Technology, Mianyang 621010, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sai-Long","family":"Wang","sequence":"additional","affiliation":[{"name":"Western Center of Disaster Mitigation in Civil Engineering of Ministry of Education, School of Civil Engineering, Lanzhou University of Technology, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhu-Jun","family":"Feng","sequence":"additional","affiliation":[{"name":"Western Center of Disaster Mitigation in Civil Engineering of Ministry of Education, School of Civil Engineering, Lanzhou University of Technology, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun-Peng","family":"Chu","sequence":"additional","affiliation":[{"name":"Shock and Vibration of Engineering Materials and Structures Key Laboratory of Sichuan Province, Southwest University of Science and Technology, Mianyang 621010, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,20]]},"reference":[{"key":"ref_1","first-page":"892","article-title":"Debris flow hazard assessment based on GIS and information method in the Bailong River Basin in southern Gansu","volume":"35","author":"Ning","year":"2013","journal-title":"Resour.
