Overall Stability Analysis of Enclosed Roadside Noise Barriers
Fully enclosed noise barriers (FENB) have been widely used in urban areas with high-rise buildings, but a new type of enclosed noise barrier with top central opening spaces (TONB) becomes an optimum proposal due to the demand for light transmission and wind resistance. This paper provides a detailed analysis of the overall stability of two enclosed noise barrier samples using the finite element method. The results show that: The combination of deadweight and uneven snow load is most unfavorable for structural buckling stability. The results of buckling coefficients show that TONB has better overall stability than FENB. The influence of geometric nonlinearity and the initial defect cannot be neglected in the calculation of critical buckling load on TONB. The critical buckling load decreases sharply when the initial imperfection increases. The initial imperfection should be minimized during the manufacturing process of TONB.
