摘要
折叠装配式框架结构具有机动性强、折展效率高、便于携带等优点,可应用于抢险救灾与部队驻训的临时活动房屋中。为保证结构的安全可靠性,利用有限元软件建立2组模块单元组装成的框架结构有限元模型,计算结构在考虑60cm积雪荷载、11级风荷载等恶劣环境作用下结构的变形、应力等静力性能,发现结构的各项静力性能均满足规范要求,能保证结构满足承载能力和正常使用极限状态。
The folding assembly frame structure has the advantages of strong mobility,high folding and unfolding efficiency,portability and the like,and can be applied to temporary mobile houses for emergency rescue and disaster relief and military training.In order to ensure the safety and reliability of the structure,the finite element model of the frame structure assembled by two groups of module units is established by using the finite element software,and the static properties of the structure,such as deformation and stress,are calculated under the harsh environment of 60 cm snow load and 1l wind load.It can ensure that the structure meets the bearing capacity and the normal service limit state.
