Abstract

In order to determine the seismic vulnerability of a structure, a vibration sensor is placed on each of the top surface of a layer of the structure and the ground surface near the structure so as to record vibrations. A seismic vulnerability data processor assumes a transfer function of vibration of the top surface of the layer of the structure based on a spectral ratio between the vibration recorded on the top surface of the layer of the structure and the vibration recorded on the ground surface, thereby obtaining a predominant frequency and amplification factor of vibration of the top surface of the layer of the structure. A seismic vulnerability index of the layer of the structure resulting from a deformation of the layer is obtained based on the obtained predominant frequency and amplification factor of vibration of the top surface of the layer of the structure and on the height of the layer of the structure. This seismic vulnerability index is multiplied by an assumed seismic acceleration so as to obtain a maximum shear strain of the layer of the structure upon being subjected to an earthquake.

In method (1), that is, a method to obtain the natural frequency of a structure by vibrating a structure, a structure is vibrated by using a vibration generator or a heavy object to give a vibration, and then the natural structure The frequency is based on the vibration generated. The natural frequency is compared to a reference value to determine the anti-shock effect of the structure. In method (2) *, that is, a method of using a checklist to obtain the seismic effect of a structure, a structure uses a schedule that includes such things as the condition of the soil under the structure, the building ’s age, Μ, and structural specifications. Project. The anti-seismic effect of the structure is determined based on the number of points given in this calculation. In method (3), that is, the earthquake diagnosis method that calculates the earthquake prevention index through structural calculation, depending on the specific situation, any one of the following three methods is used. In the first method, the highest strength of each layer is based on the paper standard of the wall using the Chinese National Standard Falcon (CNS) Α4 specification (210X297 mm) IIIIII private clothing III set-line (please read the precautions on the back first (Fill in this page) Printed and printed by the Central Sample Bureau of the Ministry of Economic Affairs, printed and printed by the Employees and Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. The description of the invention (> ") and the cross-sectional area of the beam are calculated. In the second method, the flexural strength of each layer is based on the assumption of the duration of the bare and floor slabs, as well as the calculated bending of each beam and wall and the calculated maximum shear strength of each layer, and each subsequent layer The toughness of is calculated based on the Kang system between the flexural strength and the highest shear strength, reinforcing rods, etc. In the third method, a simple non-medium structural analysis system is implemented by adding M while considering the strength and toughness of the beam. The above method for determining the seismic weakness of a structure has the following problem points. In the method of obtaining the natural frequency of a structure by vibrating a structure, a large-sized device is required to vibrate the structure, and the structure will be changed when the device is installed or when an impulse force is applied to the structure. Damaged. Moreover, this method requires a reference natural frequency as a basis for comparison, such as a theoretical natural frequency, an empirical natural frequency, or a natural frequency measured in the past. In the method of using a checklist to obtain the anti-shock effect of a structure, the evaluation is rough and will be affected by the inspector's subjective factors; the vibrational vibration of the structure cannot be obtained quantitatively. In the earthquake-preventive diagnosis method for calculating the earthquake-preventive index through structural calculation, it takes considerable time and expense to examine the information M obtained by the badger for use in the structural calculation and to register the data thus obtained. Moreover, the diagnosis requires a high degree of structural calculation knowledge, so it will inevitably require the participation of experts.
