Strengthening methods of prestressed concrete box girder bridges.

, 2019
In Lithuania and other European countries exploitation of prestressed concrete box girder bridges, built by cantilever method in 1965-1985, is a big problem. Due to defects risen from bridge exploitation bridge deck’s deflection is constantly increasing.

Stochastic Statics Analysis of Curved Thin-Wall Box Girder Bridges

, 2014
曲線橋受到荷重時其上部結構會產生較大之扭轉效應，因此曲線橋宜多採用抗扭性能良好之箱型梁來作為主梁。鑑於曲線薄壁箱型梁對參數(如材料性質、幾何尺寸、外部荷載等等)的探討多採用絕對數值，因此無法完整表現出橋梁在實際施工過程中，參數因施做誤差而造成的影響。據此，本文在曲線箱型梁翹曲扭轉分析理論中加入參數隨機性之考慮，透過響應面法，在參數隨機性作用下，探討力學行為的變化。More significant torsional effect occurs in the superstructure of a ...
