| 摘 要： | 该文以某钢桁结合梁斜拉桥为研究背景,基于外推法和Dong氏法,研究了双面V形角焊缝焊接细节热点应力集中效应,确立了热点应力计算方法,分析边界条件、网格划分对热点应力集中系数的影响。结果表明:边界条件对计算结果影响不明显,网格划分密度对计算结果影响较大,需予以重视。

| Abstract: | Taking a steel truss combined beam cable-stayed bridge as the study background and based on the extrapolation method and Dong method,the article studies the double-faced v-type fillet welding detail hotspot stress concentration effect,defines the hotspot stress calculation method,and analyzes the influence of boundary condition and gridding division on the hotspot stress concentration factor.The result makes clear that the boundary condition affects the calculation result not obviously and the gridding divi... |
