摘要
由于质量轻、抗震性能好等优点,钢结构直接加层改造技术正越来越多地应用到工程实践中。以达镖国际中心高层钢结构车库加层改造工程为例,闸明在钢结构-混凝土混合结构的加层改造设计中阻尼比取值的应力能方法,以及不同阻尼比取值下结构内力和变形的对比,并对相应结构部位的抗震加固设计进行了阐述。
Adding steel storeys on the top of the original structure is widely used in practice,for the lightness and superior anti-seismic properties.Taking the case of adding storey of high-rise steel garage and retrofit project,it was explained the strain energy methods that are applied to the calculation of damping ratio of steel-concrete mixed structure,and the comparison of the structural internal force and deformation according to different values of damping ratio.In addition,the design of anti-seismic and retrofit of corresponding parts of structure were also expounded.
