Study on In-plane Mechanical Properties of Symmetry and Non-symmetry Arch

摘要

Three two-hinge arches of 30-meter span in this paper are selected,one for symmetry semicircle shape, and the other two for non-symmetry arc shape. The three arches are all composed of I-shaped steel beams. The arch foot is gener ally classified into two categories, the fixed and the simply supported. The structure's model and analysis are opera ted by means of software midas. The element type utilized in analysis is two nodes three-dimensional beam element The period and vibration mode of the three arches are analyzed. The mechanical properties subject to horizontal load and vertical load are obtained.
