The object is to enable the calculation of load transfer paths in case of distributed load applied to the structure with the numerical structure-analysis calculation system. The value of the parameter U** at each point is calculated according to the ratio of the complementary strain energy U at the application of load without fixing the point in the structure and the complementary strain energy U′ at the application of load with fixing one point in the structure. In the actual calculation, according to the complementary strain energy U, and the flexibility matrix CAC with respect to the loading point A and one point C in the structure, and the inverse matrix CCC−1 of the flexibility matrix with respect to point C, and the load pA at the loading point A, the value of the parameter U** (CACCCC−1CCApA·pA/(2U)) at point C is calculated. Or, from the complementary strain energy U, and the inverse matrix CCC−1, and the displacement dC at point C, the value of the parameter U**(dC·CCC−1dC/(2U)) at point C is calculated.

A baggage management gate including an exciting coil, a detecting coil and signal processing unit. The exciting coil forms an alternating magnetic field in a passage to an area from which manages objects to be carried in or carried out. The detecting coil detects a variation in the alternating magnetic field when magnetization of a magnetic material showing a large Barkhausen effect is reversed in the alternating magnetic field. The signal processing unit determines as to whether the magnetization reversal occurs in the alternating magnetic field due to the large Barkhausen effect or not, based on a signal detected by the detecting coil. The signal processing unit includes amplifier that amplifies the signal detected by the detecting coil with plural different amplification factors and output the amplified signals with each of the plural different amplification factors.

The purpose of this invention is to reduce the calculation time in the numerical structure analysis system based on load-transfer-path method.The parameters are set in the condition that the supporting point B in the objective structure is fixed and the load is applied to the specific loading point A. The FEM calculation means 2 calculates the deformation of the objective structure according to the structural stiffness matrix in the stiffness matrix holding means 1 to find the basic data such as the displacement of each point and so on. The FEM calculation means calculates each deformation to find the displacement under the condition that the specific loading point A and the supporting point B are fixed and three inspection loadings are applied to the variable loading point C. The partial stiffness matrix calculation means 3 solves the multidimensional simultaneous linear equation based upon the internal stiffness matrix of the objective structure, the load value and the displacement to find the partial stiffness matrix KAC. The stiffness parameter calculation means 8 calculates the value of the stiffness parameter U* according to the partial stiffness matrix KAC and the displacement in the basic data and so on. The value of U* of each point is calculated with changing the variable loading point C as to follow sequentially all the necessary points in the objective structure.
