摘要
加层框架广泛用于旧房改造中,在用计算机对20余棍框架进行计算后,总结了这类框架在静力学,动力学方面的强度及刚度特征,提出了一些较合理的结构形式;依据工程度实际,分析讨论其技术经济特性。
Frames enlarged in floor are widely used in the Old buildings' transformation.Having calculated more than twenty frames on computer.the writers summed up the stress and stiffness characteristies of these frames in terms of statics and dynamics.some reasonable structural models are suggested in this paper.Their technical and economical features are also analysed and researched in connection with the practical constructions.
