Description
座屈波形は、圧縮局部座屈波長(L=1.72√(r・t)、r:直管部の管半径、t:直管部の管厚)と山高さ(直管部の管厚のn倍)をパラメータとしてFEMを用いてパラメータスタディを行い決定される。 Seat屈波form, compression local buckling屈波length (L = 1.72√ (r · t ), r: a tube radius of the straight tube portion, t: wall thickness of the straight tube portion) tube and crest height (straight tube portion It is determined by performing a parameter study using FEM with n times the thickness) as a parameter.
この座屈波形部1山で吸収できる変位量は最大で座屈波長であるので、座屈波形部の山数は、座屈波長と布設部位で想定される断層変位から決定する。例えば板厚9.0mm、口径600Aの鋼管で、座屈波長270mmの座屈波長部を設ける場合には、3mの断層変位が予測される部位には最低で約12山必要になる。多くの断層変位箇所の変位は1m〜5m程度と予測されるので、座屈波形部の山数は、{(1m〜5m)/座屈波長}程度設けることになる。 Since the maximum amount of displacement that can be absorbed by one buckling waveform portion is the buckling wavelength, the number of peaks of the buckling waveform portion is determined from the buckling wavelength and the fault displacement assumed at the installation site. For example, when a steel pipe having a plate thickness of 9.0 mm and a diameter of 600 A is provided with a buckling wavelength portion having a buckling wavelength of 270 mm, a minimum of about 12 mountains are required for a portion where a 3 m fault displacement is predicted. Since the displacement of many fault displacement locations is predicted to be about 1 m to 5 m, the number of peaks of the buckling waveform portion is set to about {(1 m to 5 m ) / buckling wavelength } .
座屈波形部の間隔は断層変位および断層角度を考慮し、解析を行って決定する必要があり、通常(0.5〜2)D(D:直管部の管外径)程度が適当である。座屈波形部と直管部との接合は、一体構造とするため溶接接合が望ましい。 It is necessary to determine the interval between the buckling waveform parts by analyzing the fault displacement and the fault angle, and it is usually appropriate to be ( 0.5-2 ) D (D: pipe outer diameter of straight pipe part ). is there. Since the buckling corrugated portion and the straight pipe portion are integrally formed, welding is desirable.
