摘要: 麗水蓮都靈山未來社區(qū) 37#、38#公寓式酒店為非對稱連體高層建筑,頂部 5 ~ 6 層設(shè)置了連接體,下部一些樓層設(shè)有斜柱,局部樓層收進(jìn)較多,導(dǎo)致結(jié)構(gòu)非常不規(guī)則,屬于超限高層建筑。 以 38#樓為例介紹該項(xiàng)目的抗震性能化設(shè)計情況,采用 YJK 和 MIDAS Gen 軟件對整體結(jié)構(gòu)進(jìn)行了小震和中震彈性分析,采用 SAUSG 軟件進(jìn)行了中震和大震彈塑性分析,并對連接體、斜柱、樓板、節(jié)點(diǎn)等進(jìn)行了專項(xiàng)分析。 分析結(jié)果表明,大震作用下,連接體底部的型鋼轉(zhuǎn)換桁架和關(guān)鍵節(jié)點(diǎn)均保持彈性,桁架轉(zhuǎn)換層的樓板出現(xiàn)了不同程度的損傷,其余樓層樓板基本無受壓損傷;中震作用下,斜柱未出現(xiàn)損傷,大震作用下,個別斜柱出現(xiàn)輕微損傷;結(jié)構(gòu)整體指標(biāo)合理,損傷和耗能情況良好,能夠滿足預(yù)設(shè)的抗震性能目標(biāo)。

Abstract: No. 37 and No. 38 hotel service apartments of Lingshan future community in Liandu District in Lishui areasymmetric conjoined high-rise buildings. The connector is set on the top 5~ 6 floors,some inclined columns are set on thelower floors, and partial floors have large-size setbacks. This causes serious irregularities of the structure, and these twobuildings belong to out-of-code high-rise building. Taking No. 38 building as an example, the performance-based seismicdesign of the project was introduced. YJK and MIDAS Gen software were used to conduct elastic analysis of the wholestructure under frequent and fortification earthquakes, SAUSG software was used to conduct elastic-plastic analysis underfortification and rare earthquakes,and special analysis was conducted on connectors, inclined columns, floor slabs, joints,etc. The analysis results show that the steel structure transfer truss and key joints at the bottom of the connector remainelastic under the rare earthquake, and the floor slab of the truss transfer floor is damaged to varying degrees, while the floorslabs of the other floors are basically free of compression damage. Under the action of fortification earthquake, the inclinedcolumns are not damaged, and under the rare earthquake, some inclined columns are slightly damaged. The structure hasreasonable overall indexes, good damage and energy dissipation, and can meet the preset seismic performance targets.
Keywords:out-of-code high-rise building; conjoined structure; floor slab; inclined column; performance-based seismicdesign; dynamic elastic-plastic analysis
