摘要: 打包箱式結(jié)構(gòu)是鋼框架和輕質(zhì)墻板組成的結(jié)構(gòu)體系,利用打包箱進(jìn)行模塊化設(shè)計(jì),具有可包裝運(yùn)輸、組裝靈活的優(yōu)點(diǎn)。 以三層驛站項(xiàng)目為例,利用多種計(jì)算軟件,分別對單個(gè)打包箱和多個(gè)打包箱組合的抗側(cè)剛度、極限承載力進(jìn)行分析,并對三層一組、三層兩組和實(shí)際工程的三層五箱體組合進(jìn)行分析。 分析結(jié)果表明:三層一組極限承載力及側(cè)向位移均不滿足規(guī)范要求,在進(jìn)行打包箱模塊化設(shè)計(jì)時(shí)應(yīng)避免該組合。 實(shí)際工程通過打包箱體的合理組合,可以提高結(jié)構(gòu)的抗側(cè)剛度和極限承載力,可以滿足規(guī)范要求。 多層打包箱體的模塊化設(shè)計(jì)將打包箱組合模塊化,可充分發(fā)揮打包箱結(jié)構(gòu)靈活多變的特點(diǎn),不僅形態(tài)多變,又滿足結(jié)構(gòu)受力、穩(wěn)定性等要求。

Abstract: Containerized steel modular structure is a kind of structural system with steel frame and light wallboard, by usingthe containers for modular design, it has the advantages of convenient packaging and transportation, and it is easy toassemble. Took a three-story courier station project as an example,by using a variety of analysis softwares, the lateralstiffness and ultimate bearing capacity of a single container and a combination of multiple containers were analyzed. Thecombination of three-story one-group, three-story two-group and the actual project of three-story five-group were analyzed.The analysis result show that the ultimate bearing capacity and lateral displacement of three-story one-group can not meetthe requirements of the design specification, and this combination should be avoided in the modular design of containers. Inpractical projects, the lateral stiffness and ultimate bearing capacity of the structure can be improved by reasonablecombination of containers, which can meet the requirements of the specification. The modular design of multi-layercontainers makes the combination modular, which can give full play to the flexible and changeable characteristics ofcontainerized structure. It is not only changeable in shape, but also meets the requirements of structural stress and stability.
Keywords:prefabricated containerized steel modular structure; modular design; lateral stiffness; ultimate bearing capacity;finite element analysis
