BFRP模壳不排水加固RC墩柱偏压性能分析
Analysis of biaxial performance of RC pier reinforced by BFRP shell without drainage
摘要
Abstract
Based on the eccentric compression test and numerical analysis,the compressive perform-ance of basalt fiber reinforced polymer(BFRP)shell reinforced concrete(RC)pier columns without drainage was studied.The results showed that BFRP shell reinforcement without drainage effectively improved the eccentric compressive capacity of RC pier columns.Increasing the thickness of the filling concrete layer and enhancing its strength could both significantly boost the columns' eccentric compressive bearing capacity,though excessive thickness weakened the improvement effect on deform-ation.Enhancing the constraint strength of BFRP shell connections optimized the eccentric compressive performance of the strengthened columns.An increase in eccentricity had an adverse effect on the strengthening efficiency.Additionally,a formula for calculating the eccentric compressive bearing capacity of BFRP shell-strengthened RC pier columns was proposed.The calculated results were in good agreement with measured data,providing a practical reference for engineering applications.关键词
