（天津市建筑設(shè)計(jì)院 300074）[提要] 以實(shí)際工程為例，對超高層建筑利用避難層設(shè)置水平加強(qiáng)層這一措施展開討論。通過改變外筒環(huán)梁高度、水平加強(qiáng)層的位置以及水平加強(qiáng)層的豎向彎曲剛度，進(jìn)行結(jié)構(gòu)分析，總結(jié)在側(cè)向力作用下其內(nèi)力分布規(guī)律，進(jìn)而對鋼筋混凝土簡體結(jié)構(gòu)設(shè)置水平加強(qiáng)層所能起的作用進(jìn)行了探討，在分析和比較的基礎(chǔ)上對高層建筑設(shè)置水平加強(qiáng)層的條件提出了一些建議，為今后工程設(shè)計(jì)提供一些資料。
[關(guān)鍵詞] 超高層建筑 水平加強(qiáng)層 筒體結(jié)構(gòu) 側(cè)向變形Based on practical project, using refuge story to set up horizontal strengthened story in supertall building is discussed. The structure is analyzed and its internal force distributing pattern is summarized under the conditions of different outer circline beam height, horizontal strengthened story position and its vertical bending stiffness. Furthermore, the function of horizontal strengthened story in reinforced concrete tube structure is approached. Suggestions for setting up horizontal strengthened story in high-rises are presented on the basis of analysis and comparison, which are reference materials for future project design.
Keywords: supertall building; horizontal strengthened story; tube structure; lateral displacement
