Analysis on Reinforcement Design of a special portal frame structure
The old gate style rigid frame factory building left behind due to a certain historical and cultural reason needs to be transformed into a display hall,expecting for preserving its unique historical style to the greatest extent during the reinforcement and renovation process.To study the stress and weak position of portal frames under the most dangerous load conditions,a PKPMSTS member element model and an ABAQUS finite element model were established for simulation analysis.The results indicate that the weak links of the portal frame are mainly concentrated in the beam span and the support section;The theoretical calculation results of the section with the special opening component are basically consistent with the finite element analysis results,and the bearing capacity and stability of the reinforced structure meet the current specification requirements;The overall reinforcement amount of the structure is relatively small,and the structure with cross-sectional openings is basically preserved,achieving the reinforcement goal of historical buildings.
