摘要:
為了解決配筋率、偏心距和混雜配筋面積比對混凝土柱的破壞形式、影響側向位移和柱正截面承載力計算的問題,采用構件試驗的方法,對6根鋼筋與玻璃纖維增強聚合物筋混雜配筋柱進行偏壓試驗。試驗結果表明:混雜配筋柱最終破壞形式均為混凝土壓碎且承載力較高,破壞前柱內玻璃纖維增強聚合物筋保持完好;通過合理配筋,柱延性及受拉玻璃纖維增強聚合物縱筋強度能夠較好發揮;試驗中玻璃纖維增強聚合物縱筋與混凝土截面應變分布符合平截面假定;同荷載時,柱側向位移隨配筋率增大而減小,隨混雜配筋面積比(玻璃纖維增強聚合物與鋼筋面積之比)和偏心距增大而增大。依據平截面假定,建立了混雜配筋柱正截面承載力公式,計算準度較高,供設計參考。
