［摘要］針對新疆的村鎮(zhèn)居住環(huán)境,提出了一種新型復(fù)合墻體結(jié)構(gòu)。對帶構(gòu)造柱與不帶構(gòu)造柱共10片新型復(fù)合墻體試件進行了豎向抗壓性能試驗研究。分析了內(nèi)芯強度、外模強度、高厚比以及構(gòu)造柱對新型復(fù)合墻體結(jié)構(gòu)的破壞特征、軸心受壓承載力及變形性能的影響。結(jié)果表明，不帶構(gòu)造柱新型復(fù)合墻體的軸心受壓破壞過程與普通砌體墻體的軸心受壓破壞過程相似；內(nèi)芯強度和外模強度對軸心受壓承載力影響較為顯著。在上述試驗研究基礎(chǔ)上，提出了新型復(fù)合墻體軸心受壓承載力計算公式，軸心受壓承載力的計算值與試驗值對比表明兩者吻合較好。研究成果可為該種復(fù)合墻體早日應(yīng)用到實際工程提供參考。［關(guān)鍵詞］新型復(fù)合墻體; 抗壓性能; 軸心受壓承載力; 試驗研究中圖分類號：TU364 文獻標(biāo)識碼：A 文章編號：1002-848X(2016)12-0060-07
Experimental study on compressive properties of the new composite wallYu Xiaoling, He Mingsheng, Tang Weizhong, Jiang Yong, Xia Duotian(Water Conservancy and Architecture College, Shihezi University, Shihezi 832003, China)Abstract: Aiming at the Xinjiang village living environment, a new type of composite wall structure was proposed. The compressive properties of a total of ten new composite wall specimens with and without constructional columns were tested under the actions of vertical loads. The influences of inner core strength, outer mold strength, high-thickness ratio and constructional column on the destructive characteristics, the axial compression bearing capacity and deformation properties of the new composite wall structure were analyzed. The results show that the axial compression destructive process of the new composite wall without constructional columns is similar to that for the ordinary masonry wall. And the influences of inner core strength and outer mold strength are obviously on axial compression bearing capacity. On the basis of the above experiment study, the calculation formulas of the bearing capacity for the new composite wall under axial compression were put forward. The comparison of the calculated values with the experimental values of the axial bearing capacity shows that the calculated values coincide well with the experimental values. The research achievements can provide reference for the application of this kind of composite wall in practical engineerings as soon as possible.Keywords: new composite wall; compressive property; axial compression bearing capacity; experiment study
