首先，針對以往計算中，部分模型參數模擬不準確的問題，根據現場實測數據，運用ansys優化功能對混凝土動彈模和屋頂桁架桿的軸向剛度進行了反演，用反演的參數結果建立模型進行模態分析與實測數據符合較好。The contents include : based on the previous research and the data of experimentations, the author researches and develops a kind of satisfactory semi - empirical formula of nonlinear temperature distribution, and calculates the temperature stress of rigid - framed arch bridge by the fem. the temperature effects of bridge structure by annual and sunlight temperature difference are discussed, it indicates that the temperature effect of annual temperature difference is small but the temperature effect of sunlight temperature difference is great and the temperature stress along beam depth resulted from sunlight temperature difference is nonlinear. with the comparison between the temperature effects of different position of bridge, the results show that where the section of bridge is small, the temperature stress of it is large
本文主要包括以下內容：從理論上研究並結合實測資料發展了一種比較理想的半經驗溫度場非線性分佈公式，並將有限元方法應用於剛架拱橋結構溫度應力的計算中，對橋梁結構進行整體溫度應力分析；討論了年溫差和日照溫差引起的橋梁結構的溫度效應，表明年溫差引起的溫度效應較小，而日照溫差引起的溫度應力較大且沿梁高呈非線性分佈；分析比較了橋梁結構各個部位的溫度效應的大小，可知截面越小溫度拉應力越大，受力越不利；並對箱梁結構由於構造不同引起的縱向與橫向的溫度效應大小進行了探討，發現在頂板下緣也會出現相當大的溫度拉應力，並且梗腋的存在反而增加了頂板底部的溫度拉應力；還對幾種相近的剛構式橋型的溫度效應進行了分析對比，總結了這些橋型針對溫度效應的優劣，並提出相應的針對性措施。This paper introduces the chips, hardware and software of hdtv stbs available in the market, and analyzes and compares their features
