Research On Lateral Resistance And Fire Performance Of Container House

Along with social development, the application of container house is morewidely, developing from industrial occupancy to residential occupancy. Theapplication of container modularity makes it appear a variety of architectural forms.It may foresee that container house has very good application prospect. Theapplication and market promotion of domestic container house is still in thepreliminary stage of research.This paper has researched the lateral displacement of container structure in twocases which side panels have symmetric openings and no openings. The sheardeformation formula of profiled sheet, of which two ends are welded to thesupporting structure, has been derived. According to the analysis, the main way ofstructure deformation is local compression deformation when horizontal loads areapplied at the ends of container with no openings. The top beams first reach theyield when the horizontal loads are applied to270kN. Finally, the sway formula ofcontainer is attained under horizontal loads. According to the boundary conditionsof the underbeam, two cases are considered when analysing the container withsymmetric openings. When the bottom beam is fixed, the global deformation ofstructure and the axial deformation of beam are calculated. The global deformationis calculated according to the equivalent frame, and calculation of axial deformationuse an approximation method. When the bottom beam is not fixed, the axialdeformation of beam is ignored beacause the integral stiffness is smaller than theaxial stiffness of top beams. So the structure is devided into frame part and shearwall part. Then calculate the sway of two parts separately. Finally, consider theinteraction of two parts through the compatibility of deformation.This paper has calculated lateral displatement value of20ft container under thehorizontal loads according to the theoretical formula. The results are compared withthe results analysed by ABAQUS finite element software. In addition, based on thedistribution of deformation and stess by ABAQUS, the assumption which sheardistribution is linear between top beams and profiled sheet is justified.This paper also uses performance-based fire protection method to analyseperformance of container building under fire. FDS fire simulation software is usedto attain the air temperature field. Combined with finite element software ABAQUS, this paper makes structural analysis of the container and attains the disformationunder fire. Then compare with the result under standard fire. The Fire-resistingperiod is about25min under standard fire. The ultimate temperature is about800℃.Fire-resisting period under simulated fire is longer than under standard fire. Thestructure has not collapsed under simulated fire. Structural members may not adoptfire protection measures in the fire protection design. However, due to limited bycorner fittings, the bottom beams soon reach full-section yield under fire. Fireprotection measures are recommended to adopt on the bottom beams in the fireprotection design.
