Abstract
Based on an office building' s strengthening project, this paper conducts the construction finite element analysis using SAP2000 to its double-beam reinforced concrete frame underpinning construction process. The results are compared with data of the RC-beam' s deflection and strain from monitoring test under construction. Analysis presents unloading phenomenon of axial force reduction in some remaining small walllimbs after the removal of the load-bearing walls at bottom. The existing small wall-limbs and walls lacking of shear-bearing abilities are strengthened by GFRP (Glass Fiber Reinforced Polymer). The conclusion of this paper shows that this method is safe, feasible and practical in strengthening of structures.关键词
