新型复合空腹夹层板楼盖力学性能有限元分析

Finite element analysis of mechanical properties of a new type of composite hollow sandwich floor

对新型复合空腹夹层板楼盖的构造进行了介绍,通过有限元分析软件ABAQUS模拟新型复合空腹夹层板楼盖在静力荷载作用下挠度、破坏及自振周期。模拟结果表明:与钢筋混凝土空腹夹层板楼盖相比,新型复合空腹夹层板楼盖在同级静力荷载下挠度减小,楼板自振周期增大,能够使结构远离地震卓越周期,减轻地震破坏。

Introduces the structures for new composite vierendeel sandwich plate roof, finite element analysis software ABAQUS was used to simulatethe deflection, failure and self vibration period of the new type floor under static load. The result shows： compared with reinforced concretehollow sandwich floor, the deflection of the new floor was decreased under the same static load, self vibration period of floor was increased, it canmake the structure far away from the earthquake preeminent period and reduce the earthquake damage.
