【摘要】 使用脉动测试方法,对某高层钢结构建筑无挂板、有挂板两种实测模态进行对比,为工程设计提供依据.试验表明,钢结构挂板对整个结构的阻尼和刚度有较大影响,在结构抗震计算中挂板对钢结构的作用不可忽视.更多还原

【Abstract】 The comparion is made between two measured modalities of a steel structural highrise building with or without cladding panals by using pulsation test. The analysis research can be used for engineering design. The test shows that the cladding panals of steel structure have noticeable influence on the damping and rigidity of the whole structure, and the influence of cladding panals on steel structure should not be neglected in the aseismic calculation.更多还原
