Abstract
Against the backdrop of technical upgrading,green revamping,and digitalization across cane sugar industry,retrofit projects in existing plants often reveal punching and one-way shear deficiencies around column bases under equipment replacement and load increases.This study develops a steel plate shear frame foundation strengthening scheme.By leveraging the composite action of shear studs-steel grid plates-bearing plates-encased concrete,the method redistributes column loads and mitigates localized stresses.Code checks and 3D finite-element analyses(using Midas FEA NX finite element analysis software),together with an engineering validation,were conducted.Results indicate that,compared with the unstrengthened condition,the method significantly reduced the peak stress in the punching control zone and shear section to 29.8%and 45.2%of their original levels respectively,effectively alleviating stress concentrations.Field settlement monitoring under the actual equipment operating load demonstrated that the foundation deformation was stable and uniform.The differential settlement satisfied relevant code requirements,confirming the effective stiffness coordination and overall load-bearing reliability of the strengthening system.The method is efficient,economical,and constructible with minimal downtime,making it well suited for rapid foundation strengthening in technical-upgrading projects of sugarcane sugar plants.关键词
