The high strength concrete filled steel tubular member ( hcfst ) are increasingly applied to civil engineering construction in large quantity because of its super performance . , however , the shortage of full knowledge of creep of this member prevents us from further using it correctly and extensively . therefore . it ' s necessary to explore the mechanisms of creep of cfst member and influence of creep on mechanical performance of hcfst member 鋼管高強混凝土組合構件因其優(yōu)越的性能日益廣泛地為工程界所應用,然而對這種構件徐變性質的認識不足卻制約了它的正確使用和推廣應用,因此,深入探究鋼管高強混凝土構件徐變機理、準確計算其徐變值并充分認識徐變對構件力學性能的影響非常重要。
