The paper gives the calculation formula of the steel box beam rib plate, side line length and coordinate of transition curve sections combined with construction practice.
In this paper, a new quadrilateral thin-thick plate bending element with only 12 degrees of freedom, TACQ, is developed by using the area coordinate method.
In this article, the method is described for measuring the scales of the two coordinate axes of a CCD plate through astronomical observations and the nonperpendicularity of the axes.
