开孔板连接件受剪承载力研究
Research on shear strength of perfobond rib connectors
摘要
Abstract
Based on previous researches,the failure modes of perfobond rib (PBL) connectors with single hole and parameters affecting the shear strength of PBL connectors were analyzed,and an effective model was developed to estimate shear strength of PBL connectors with single hole where the thickness of steel plate was not smaller than 9 ram.The lateral constraints provided by concrete around the steel plate,perforated rebar and friction on the subface of specimens could restrain the connectors,and enhance the shear strength of PBL connectors.The constraining mechanisms of concrete,perforated rebar and friction were considered in the model.Then,the formulas to calculate the shear strength of PBL connectors with single hole was obtained by fitting of experimental data.At last,the shear bearing capacities of these specimens were evaluated by the formulas in this paper and formulas reported before.By comparing calculating results with experimental results,it is found that the model in this paper can consider the influences of concrete around the steel plate,perforated rebar and friction on the subface of specimens rationally,and the calculating results of the proposed formulas agree with experimental results well.关键词
