［提要］ 通過12根三面高溫時鋼筋混凝土軸心受壓柱在不同溫度下的試驗(yàn)，研究了高強(qiáng)混凝土（C60）軸心受壓柱在不均勻溫度場下的力學(xué)性能，并與普通強(qiáng)度混凝土（C30）軸心受壓柱進(jìn)行了比較。試驗(yàn)結(jié)果表明，在不均勻溫度場下的高強(qiáng)混凝土軸心受壓柱強(qiáng)度和變形與溫度、箍筋用量、荷載溫度途徑及預(yù)加荷載水平有關(guān)。［關(guān)鍵詞］ 高溫; 高強(qiáng)混凝土; 軸心受壓柱; 強(qiáng)度; 變形Abstract: Through the test of 12 reinforced concrete axial compression columns heated on their three surface at different temperature，the behavior of high-strength reinforced concrete axial compression columns with non-uniform temperature field was researched，and was compared with that of normal-strength reinforced concrete axial compression columns．It is shown that the strength and deformation of high-strength reinforced concrete axial compression columns with non-uniform temperature field are related to the temperature reached，the quality of hoops，the loading and heating paths，as well as the pre-load level．Keywords：high temperature；high—strength reinforced concrete；axial compression column；strength；deformation
