Method for calculating vibration comfort level of buildings around subway based on non-uniform excitation

The invention discloses a method for calculating the vibration comfort level of buildings around a subway based on non-uniform excitation. The method comprises the following steps: S1, establishing a subway non-uniform vibration load database; s2, establishing a power spectrum model of the subway non-uniform vibration load; s3, synthesizing a subway non-uniform vibration load; and S4, calculating the building vibration response based on comfort evaluation. According to the invention, the load model is established based on a large amount of actual measurement and numerical simulation data, influences of various factors are considered, and better universality is achieved; according to the invention, an independent building model is adopted, a soil body model and an iterative algorithm considering vehicle-structure coupling are avoided, and refined processing of the building model based on comfort evaluation can be further supported while the calculated amount is greatly reduced; according to the invention, the non-uniform excitation effect of the subway load is considered, and the vibration response of the building can be more reasonably and accurately calculated.
