Seismic Performance Analysis of Hazardous Solid Waste Storage Facilities

Hazardous solid waste has very strict requirements on storage facilities due to its own hazard-ous nature.In order to study the seismic performance of hazardous solid waste storage facilities,ABAQUS software was used to establish a finite element model of the storage facility and to analyze the structural strength und er earthquake action.The models were divided into a single-tube model and an integral model.The single-tube model consists of a single storage tube with multiple hazardous solid wastes,while the inte-gral model consists of 48 storage tubes,and the supporting fames,columns and footings.For the single-tube model,the time history analysis under earthquake action was performed to obtain the force of the haz-ardous solid waste on the supporting frame,and this force was considered in the integral model;for the in-tegral model,the calculation was performed by modal analysis and mode-superposition response spectrum method.The calculation results show that the strength of hazardous solid waste storage facilities meets the requirements of relevant codes,and the maximum stress occurs at the mid-level supporting structure.This study provides a reference for the design and engineering application of hazardous solid waste storage facili-ties in the future.
