新型复合墙体的有限元建模技术研究

FINITE ELEMENT MODEL ANALYSIS OF A NEW COMPOSITE WALL

密肋复合墙体作为密肋壁板结构的主要受力构件,其受力特性、构造处理和连接方式比较复杂。用非线性有限元分析方法可以给出密肋复合墙体内力和变形发展的全过程、描述裂缝的形成和扩展以及墙体的破坏过程、破坏形态,对于实际工程和科学研究具有足够的精度;同时,针对试验研究的局限性,通过试验验证的有限元计算模型可以提供结构更多的反应信息,从而建立更为有效的结构简化计算模型。

Being main bearing members of a multi-ribbed slab structure, the forced characteristics, tectonic measures and connections of a muhi-ribbed composite wall are complex. By using nonlinear analysis, forces and the whole process of deformation development are given. Cracks emergence and widespread and failure processes and patterns of the walls are descripled. Meanwhile, the finite element calculation model verified by test can provide more reactive information to establish more effective structure calculation model.
