［摘要］青島加洲國(guó)際客運(yùn)中心項(xiàng)目為A級(jí)高度大底盤(pán)雙塔樓框架-核心筒結(jié)構(gòu)，主體完工后成為爛尾樓。現(xiàn)由于建筑功能改變及立面調(diào)整，對(duì)其進(jìn)行了外擴(kuò)、增層、拔柱、開(kāi)洞、補(bǔ)洞等一系列改動(dòng)。由于原設(shè)計(jì)整體計(jì)算參數(shù)有一定富余，故后續(xù)設(shè)計(jì)使用年限取50年，按現(xiàn)行規(guī)范進(jìn)行加固改造設(shè)計(jì)。設(shè)計(jì)中充分發(fā)掘已有結(jié)構(gòu)潛力，盡量避免梁板加固；采用鋼箍板加固底部暗柱以保證加固后的底部加強(qiáng)區(qū)滿足現(xiàn)行規(guī)范要求；通過(guò)增設(shè)鋼斜撐形成平面桁架結(jié)構(gòu)，從而實(shí)現(xiàn)1層大堂拔柱；合理設(shè)計(jì)增層生柱及新增懸挑梁，避免了過(guò)量植筋對(duì)原結(jié)構(gòu)的損傷。通過(guò)采取以上措施，較好地實(shí)現(xiàn)了建筑功能的改變。［關(guān)鍵詞］大底盤(pán)雙塔樓; 框架-核心筒結(jié)構(gòu); 加固改造; 鋼箍板; 拔柱; 增層; 植筋中圖分類(lèi)號(hào)：TU746.3 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)05-0001-07
Reinforcement and reconstruction design of Qingdao Jiazhou International Passenger Transport CenterSun Shaodong, Zhao Lin, Li Jing, Zou Lianjie, Chen Huirong(Qingdao Tengyuan Design Institute Co., Ltd., Qingdao 266100, China)Abstract:Qingdao Jiazhou International Passenger Transport Center with A-level height became a half-baked building after completion of main structure. Frame-corewall structural system is adopted in this twin towers with large chassis. Due to architectural function modification and facade adjustment, a series of changes were made, including annex expansion, adding stories, pulling up columns, holing and filling holes. Because there is certain surplus in whole calculating parameters of original design, subsequent service life was designed to 50 years, and current codes were used for reinforcement and reconstruction design. Existing structural potential was fully excavated in design in order to avoid reinforcement of beams and plates as far as possible. To meet requirements of current codes on bottom reinforcing area, hooped steel plates were used in reinforcement of bottom embedded columns. Through adding steel diagonal bracings to form plane truss structure, columns of first floor lobby were successfully pulled up. By rational design of adding stories, newly added columns and cantilever beams, damage to original structures caused by excessive planted bars was avoided. The modification of architectural functions were satisfactorily realized through above methods.Keywords:twin towers with large chassis; frame-corewall structure; reinforcement and reconstruction; hooped steel plate; pull up column; adding story; planted bar
