摘要: 某項目停工續(xù)建時建筑功能由原辦公用房變更為商務酒店用房,導致結構荷載增加、出現(xiàn)斜柱等重大變更. 首先介紹了結構續(xù)建設計的主要特點:斜柱過渡方案的選擇、樓蓋水平拉力系統(tǒng)的確定、第 17 層核心筒三個角部型鋼柱與型鋼梁的連接、中震作用下底部墻肢拉應力的解決辦法等. 然后對主體結構進行了小震彈性時程分析和大震彈塑性動力時程分析,對部分重要和受力復雜構件進行性能化設計. 計算結果表明結構的各項指標均符合規(guī)范要求,結構具有良好的抗震性能,安全可靠.
關鍵詞: 超高層結構; 非正交對稱軸網(wǎng); 抗震性能目標; 斜柱過渡

Abstract: The architectural function of a project was changed from the original office room to the commercial hotel room,resulting in significant changes of the increase of structural load and the emergence of inclined columns. Firstly, the maincharacteristics of structural continuation design were introduced, such as the selection of inclined column transition scheme,the determination of floor horizontal tension system, the connection between steel column and steel beam at three corners ofthe 17 floor core tube, and the solution of tensile stress at the bottom wall under middle earthquake. Then, the elastictime?history analysis of the main structure under small earthquake and the elastic?plastic dynamic time?history analysisunder large earthquake were carried out, and the performance?based design was carried out for some important and complexcomponents. The calculation results show that each index of the structure meets the requirements of the code, and thestructure has good seismic performance which is safe and reliable.
Keywords:super high?rise structure; non?orthogonal symmetric grid; seismic performance objective; inclined columntransition
