Beschreibung
Zusammenfassung:	A behavior estimation method includes a first step of calculating number of earthquake resistant joints required for absorbing a fault displacement amount in a pipe orthogonal direction, based on an allowable deflection angle and a pipe effective length, and calculating a deflection range in a pipe axis direction, a second step of calculating a load, received by the pipe due to relative displacement between the pipe and ground corresponding to a ground spring model in the pipe orthogonal direction defined with spring constants respectively for relative displacements smaller and larger than a predetermined relative displacement, a third step of calculating a bending moment distribution of joint positions from a bending moment of a trapezoidal distribution load, and obtaining a pipe deflection angle at each of the joint positions based on a predetermined joint deflection spring model, and a deflection performance evaluation step.
