A method I divide it while the first puts a ground support under the bridge, and hanging it by a crane, and to remove, the second are the fulcrums or, in the neighborhood, cut the lower part of the bridge and are law to remove at a stretch. The latter continues having a good point that I finish cost cheaply predominantly in comparison with the former and has the bad point. The fall removal was said to have a problem in a safety and scattering thing. Most are based on experience, and this is because it lacked in a dynamics mark and grounds to investigate security analytically. This study provided data aiming at safe establishment by the fall removal method of the steel bridge.}, title = {鋼橋の落下解析}, volume = {46}, year = {2012} }
