According to the test result, the mechanism of inorganically post - installed bars with cone - shaped heads was analyzed. and then the anchor intensity formula was formulated. the inorganically post - installed bars with cone - shaped head was carried on the finite element analysis on the spatial axial symmetry model
根據試驗結果，對帶錐頭無機植筋的受力機理進行了理論分析，推導出帶錐頭無機植筋的錨固強度公式，並利用空間軸對稱模型對帶錐頭無機植筋進行了有限元分析，提出了利用桿單元模擬鋼筋與混凝土之間的粘結滑移關系的方法。 -
Modeling the general solid web continuous box girder and opening - in - web ( open web ) continuous box girder by ansys finite element modeling tool, node stress of governing section and corresponding shear lag values are analyzed. the solution is validated by comparing with variational results and modeling test values. based on the model, the section shear lag induced by dead load, prestress tendons and car loads under the most unfavorable condition and lateral symmetry are also approached. the influence of shear lag effect in double - level continuous box girder is considered with opening - in - web and the web location. the analysis indicates that double - level - load arouses less shear lag effect than one - level - load. when self - weight and prestressed tendons act on together, the shear lag effect on box girder take on a evidently change
基於所建立的有限元模型，本文分別對實腹和腹板開孔兩種箱梁在恆載、車載、預應力荷載作用時，各主要截面的剪力滯效應進行分析，通過施加縱向最不利的和橫向對稱的車輛荷載，研究實腹連續箱梁和空腹連續箱梁在承受雙層荷載和單層荷載時引起的剪力滯效應，並考慮腹板開孔及開孔位置對于連續箱梁剪力滯效應的影響。分析表明，雙層車載對于箱梁引起的剪力滯系數比單層車載的影響要小，對于箱梁中存在引起的剪力滯后現象有一定的改善作用。 -
Moreover, with the datum come from calculation and test, it seams that after the number of batten floor n > 3 the change of b effected by n is too weak to be ignored. hence, that indicates it is available that the laterlly buckle of the batten column with the single axis of symmetry could be calculated with b worked out from h - shaped anglicizing element without n
此外，由電算和實驗分析可見，值在綴板層數n 3以後，其變化受n值的影響不大，這說明用h計算單元導出的與綴板層數無關的值計算公式是可以用於單軸對稱綴板柱的側向屈的計算。 -
