［摘要］大連國(guó)際會(huì)議中心的筒體采用“鋼管角柱-鋼桁架暗支撐架混凝土組合核心筒”。該結(jié)構(gòu)各核心筒均根據(jù)建筑的需求開(kāi)設(shè)了洞口，且整個(gè)結(jié)構(gòu)質(zhì)量、剛度分布不均，筒體受力較為復(fù)雜。在核心筒的抗震設(shè)計(jì)中，如何保證筒體角部鋼管柱柱腳與混凝土基礎(chǔ)具有良好的共同工作性能，保證結(jié)合部位的錨固性能，是其關(guān)鍵技術(shù)之一。對(duì)這部分鋼管柱進(jìn)行抗拔試驗(yàn)研究，以確保在地震作用下整個(gè)筒體以及結(jié)構(gòu)的安全。試驗(yàn)表明，混凝土基礎(chǔ)中配置豎向抗拔鋼筋和水平分布鋼筋均能有效提高抗拔柱的錨固承載力。
［關(guān)鍵詞］核心筒；鋼管受拉角柱；錨固性能；拉拔試驗(yàn)

Abstract:The cylinder body of Dalian International Conference Center adopts“steel tube-reinforced concrete column frame-concealed mesh steel truss concrete composite core tube”. The core tubes are set up caves according to the building needs, the distribution of the-whole structural mass and stiffness are not uniform, and the stress is more complex. In the seismic design of the core tube, how to protect the good working performance of steel tube-reinforced concrete column and concrete foundation, and guarantee the anchorage performance, is one of the key technologies. The experiment of the uplift column was carried out to ensure the safety of the cylinder body and the structure under-earthquake. The experiment results show that the uplift and horizontal steel in the concrete foundation can effectively improve the anchoring capacity of uplift column.
Keywords:core tube; steel tube tensile prism; anchorage performance;  uplift column test
