도심지 L형 측구 집수정 스틸그레이팅에 대한 유한요소 해석

초록

In this study, structural analysis and calculations were conducted on the downward and vehicle loads to reduce vehicle accidents caused by the failure of steel gratings, and the results were compared and analyzed. To replicate the severe circumstances found in the steel grating, a vehicle load was applied at T20 and T14. Finite elements and geometric nonlinearity were applied to the material and contact in the structural analysis. As a result of the analysis, plastic sagging of the steel grating owing to the downward load and vehicle load did not occur. However, local plastic deformations occurred in the welded parts of the I-bar and crossbar. The analysis results confirm the need for strength improvements in vulnerable areas.
