HPFL 加固预制空心板的数值模拟与试验研究
Numerical Simulation and Experimental Investigation on Precast Hollow-core Slabs Strengthened with HPFL
摘要
Abstract
Based on the experimental study of the flexural performance and shear performance of pre-cast hollow-core slabs strengthened with HPFL,the ANSYS was applied to build the spatial finite element model to analyze the precast hollow-core slabs strengthened with HPFL.Further analysis was conducted for the HPFL strengthening surface mortar strength,HPFL reinforcement layer steel bar mesh size,HP-FL reinforcement stripe width and the direction of precast hollow slabs and other factors on the precast hollow slabs shear performance strengthened with HPFL.The results demonstrate that finite element a-nalysis results and the experimental results are basically identical and the effectiveness of HPFL as a kind of improved precast hollow slabs flexural resistance and shear resistance.The HPFL stripe width and the strengthening surface mortar strength have the most important influence on the strengthening effects.The ultimate capacity increases with their enlargement.The ultimate capacity increases slightly with the steel bar mesh size.HPFL can also improve the precast hollow slabs'shear bearing capacity of horizontal and vertical directions.关键词
