Abstract

The invention relates to a method for solving seismic collision reaction parameter complexity of a building structure, and belongs to the technical field of civil engineering. The method comprises thefollowing steps: S1, constructing a collision force model; S2, constructing an adjacent structure collision dynamic equation; And S3, applying a dimension analysis method. According to the method, single variables are mutually combined into a small number of dimensionless variables, and the function relationship among all sets of dimensionless variables is obtained, so that the analysis process is simplified, the essence of the problem is defined, and the complex problem is explained simply and clearly. A dimensionless collision reaction mathematical model of adjacent structures under the action of strong earthquake is established, dimensionless parameters with a small number and clear physical significance are used for representing structure collision reaction, clear and comprehensive structure collision reaction laws are revealed, and meanwhile the self-similarity of the structure collision reaction is revealed.

Description

technical field [0001] The invention relates to a method for solving the complexity of seismic collision response parameters of building structures, which belongs to the technical field of civil engineering. Background technique [0002] Earthquake disasters seriously endanger building structures and life safety. Collision between adjacent building structures is one of the typical earthquake damages and one of the important reasons for structural damage and even collapse, which can easily cause casualties and national economic losses. Collision damage of engineering structures has occurred in large numbers in past earthquakes. [0003] The impact response of structures under strong earthquakes is not only affected by the characteristics of adjacent structures, but also closely related to the characteristics of ground motion. It is a highly nonlinear problem involving many parameters. influence parameters. Although scholars in the past have conducted corresponding research ...
