［摘要］結(jié)合無錫藍(lán)庭國際在層8轉(zhuǎn)換的部分框支剪力墻結(jié)構(gòu)設(shè)計(jì)，分析了帶高位轉(zhuǎn)換結(jié)構(gòu)的豎向規(guī)則性，發(fā)現(xiàn)在轉(zhuǎn)換層處，框支柱、剪力墻存在剪力突變，轉(zhuǎn)換層下一層與轉(zhuǎn)換層剛度比小于50%。結(jié)合該工程設(shè)防類別及規(guī)則性，針對(duì)結(jié)構(gòu)和關(guān)鍵構(gòu)件提出不同的抗震性能設(shè)計(jì)目標(biāo)。對(duì)轉(zhuǎn)換層及其上下層樓板在各級(jí)地震作用下的樓板應(yīng)力進(jìn)行了分析，并給出了便于工程應(yīng)用的轉(zhuǎn)換層樓板配筋計(jì)算方法。合理布置結(jié)構(gòu)，避免結(jié)構(gòu)剛度柔軟層為承載力薄弱層。彈塑性分析表明，經(jīng)過合理布置后的結(jié)構(gòu)無明顯薄弱層，具有良好的屈服機(jī)制。

Abstract: Based on structural design on a frame-supported shear wall structure of Wuxi Lanting Guoji with transfer story at the 8th floor, the vertical regularity of high transfer structure was analyzed. The results show that shear force of the column which supports transfer beam and shear wall mutates near the transfer story; the stiffness ratio of transfer story and the story below was less than 50%. Based on the seismic fortification and regularity of the project, aiming at structure and key elements, different structural seismic performances were presented. The slab stress of transfer story and the story below (above) under different seismic load was analyzed. A calculation method for reinforcement of transfer story slab was proved. Soft story can be avoided to be weak story by reasonable layout of the structure. Results of elasto-plastic analysis indicate that the structure has no obvious weak story, and it has an excellent yield mechanism.

Keywords: high transfer story; storey height of transfer story; vertically irregular; slab design method of transfer story
