| 摘 要： | 对某制氢化工厂厂房转换层进行刚接和铰接工况下的地震反应谱对比分析.结果表明,转换层分别采用铰接和刚接方案时,结构的动力特性规律基本一致,但铰接比刚接的刚度略低,使得结构的基本周期变长,抗震性能略微下降；铰接方案对转换层位移影响较大,该方案使转换层及底层混凝土柱子的剪力和弯矩减小,部分柱子轴力略有提高,改善了其受力性能. |

| Abstract: | Seismic spectrum research was carried out of the transfer floor in a certain hydrogen chemical plant with rigid joints and pinned joints.The results show that,when rigid joints and pinned joints are used,respectively,the structure has the same dynamic properties yet its rigidity is a bit smaller with the use of rigid joints,which results in the longer fundamental period and poorer aseismatic performance of the structure.It is also found that pinned joints has a great influence on the displacement of the tra... |
