摘　　要：为了完善轻型可移动房屋结构的设计理论与方法,通过灾后恢复重建实际调查及野营房屋的使用情况调查,划分了轻型可移动房屋的设计使用年限。基于可靠度设计方法,依据概率理论极限状态设计准则,运用校准法得到不同设计使用年限房屋的目标可靠指标,在此基础上建立了移动房屋承载能力极限状态的分项系数设计表达式。运用蒙特卡罗方法和响应面模拟分析方法,对正常使用极限状态下可移动房屋适用性变形进行分析,给出了基于目标可靠指标下的可移动房屋主要受力构件的变形限值,为轻型可移动房屋结构设计与分析提供了可靠的理论依据。To improve the design theories and methods of lightweight movable house structures,the design working life was specified through actual investigation of post-disaster reconstruction and service condition of camping houses.Furthermore,according to the reliability design method and probability-based design criteria,the reliability index of houses with different design working life was obtained by calibration method.And on this basis,a design expression of partial coefficient was established for movable houses at bearing capacity limit state.In addition,through using Monte Carlo and Response Surface methods provided by ANSYS finite element software,the applicable deformation was analyzed for movable houses at normal using limit state and the deformation limits were obtained for main bearing members.The result can provide theoretical reference for the design of lightweight movable houses.
