摘要
对适用于建筑物增层的轻钢体系的特点以及适用范围进行介绍,探讨轻钢增层设计中的一些计算方法,提出以底部剪力为目标参数的最优加层数,分析最优加层数下结构的反应,以此评判原结构的加层能力。从材料成本的角度对不同材料增层的经济性进行分析比较,给出评价结果。并以某加层工程为实例,用此方法选择合适的加层方案。
Characteristics and applying conditions of lightweight steel structures in adding buildings are introduced, and the correlative calculating methods of designing them are also discussed. The optimal in adding layers are proposed by using bottom storey shear as target parameters. The reactions of structure adding optimal layers are analyzed to judge the adding capacity of original structure. The economy comparison of different materials of adding layers is also discussed by the parameter of material cost. Using an adding project as an example, an appropriate adding scheme is chosen by thi＇s method.
