摘　　要：集装箱式钢结构建筑以集装箱为单体进行组装,具有装配式和模块化建筑的优点,发展前景较好。但目前国内外学者对集装箱式钢结构建筑的研究大多数是基于建筑学角度或单箱体的结构力学性能角度,关于波纹板墙体的简化模拟及集装箱式钢结构房屋结构设计方法的研究有所欠缺。通过对波纹板的简化模拟方法进行归纳和总结,提出了竖向承重与水平抗侧相结合的波纹板墙体简化模拟方法。首先利用有限元软件建立波纹板墙体模型,在墙体模型顶部端点加载,通过有限元分析得到波纹板墙体顶点荷载-位移关系,由此计算墙体的初始水平抗侧刚度;然后在设计软件中建立上下横梁和角柱的结构模型,并将波纹板等效为交叉支撑,由刚度等效原则计算交叉支撑的截面面积,从而在设计软件中实现波纹板墙体水平抗侧刚度的模拟。同时,根据面积等效的原理将每个波纹简化成一个两端铰接的立柱,并与集装箱式钢结构房屋本身的上下横梁连接,从而实现波纹板墙体竖向承载力的模拟。对于多层集装箱式钢结构建筑,建议采用GB 50017—2017《钢结构设计标准》中高承载力-低延性的抗震设计思路,按多遇地震和设防烈度地震的地震作用进行杆件设计,同时放宽构件的宽厚比限值。采用上述方法对某双层双车位集装箱消防站进行分析,采用ANSYS软件分析波纹板墙体的抗侧刚度,考虑波纹板开洞对刚度的折减作用;然后用等效交叉支撑及两端铰接的小立柱模拟波纹板墙体,并在PKPM中建立结构分析模型。在PKPM中将塑性耗能区承载性能等级设置为性能3,延性等级设置为V级,截面板件宽厚比最低等级设置为S5。按照GB 50017—2017要求进行梁、柱及支撑构件的多遇地震和设防烈度地震下承载力验算,结果表明:各构件均满足地震下承载力要求;同时结构的最大层间位移角为1/527,集装箱�Container buildings are assembled with many standard containers,and they have a good application prospect with the advantages of fabricated and modular buildings.However,most of the researches on container buildings focus on the architectural design or the mechanical performance of single box structure.The simplified simulation methodologies of corrugated sheet wall and structural design method of container buildings are lacking.By summarizing the simplified simulation methods of corrugated sheet wall,a simplified simulation method of corrugated sheet wall with considering both the vertical bearing and horizontal lateral resistance was presented.Firstly,a corrugated sheet wall model was established by using finite element software,and concentrated force was applied to the top end of the wall.The force-displacement relationship curves of corrugated sheet wall were obtained through finite element analysis,and the initial horizontal lateral stiffness of the wall could be calculated.Then the structural model of upper and lower beams and corner columns of the corrugated sheets were setup in the design software,and the functions of the corrugated sheet wall was simulated by cross braces,and the crosssectional area of cross brace was calculated according to the stiffness equivalent principle.Thus,the simulation of the horizontal lateral stiffness of the corrugated sheet wall was realized in the design software.Besides,each corrugation was simplified into a column with hinged upper and lower ends according to the principle of area equivalence,which was connected with the upper and lower beams of the containers,thus realizing the simulation of the vertical bearing capacity of the corrugated sheet wall.For multi-storey container buildings,the performance-based seismic design principle of high bearing capacity and low ductility was used according to Standard for Design of Steel Structures(GB 50017-2017).The members were strength checked according to the seismic forces under frequent earthquke and intermediate earthquake,and
