大型火电厂主厂房钢支撑-框架结构振动台试验模型

Shaking Table Test Model with Steel Braced-Frame Structure About Main Plant of Large Thermal Power Plant

为了在振动台上实现大型复杂钢支撑-框架结构的模拟地震试验,以某现役大型火电厂主厂房结构为原型,根据结构静、动力性能等效原则,设计制作了大缩比振动台试验整体模型。采用钢板模拟钢-混凝土组合楼板,工形钢梁模拟钢桁架,小螺栓节点连接模拟高强螺栓连接等尽可能反映结构实际情况的制作方案和措施,探索了细部构造对整体模型影响的途径,为中国首次实现同类结构的抗震性能试验研究奠定了基础。

In order to realize simulated seismic test of large complex steel braced-frame structure at shaking table, regarded main plant structure of some active service large thermal power plant as prototype and according to equivalent principle of structural static and dynamic property, the whole large scale shaking table test model was designed and made. Facture project and measure reflecting practical situation of structure which used steel slab to simulate floor slab; used I-type steel girder to simulate steel trusst used small screw joint connection to simulate high-strength bolt connection, et al were carried out. Authors explored the way with influence of detail construction on the whole model which established basis for research on anti-seismic property test of the same type structure in China for the first time.
