摘要
对现浇双向板与双拼叠合式双向板进行静力加载试验,主要对比这2种板的挠度及裂缝开展等方面在均布荷载下的受力差异情况。足尺试验表明,现浇双向板与这种双拼叠合式双向板在受力性能上基本一致。由此可得,双拼式叠合板的挠度曲线可用弹性薄板理论计算,这个足尺试验为DB34/T810-2008《叠合板式混凝土剪力墙结构技术规程》的修订提供理论依据,为加快推进装配式建筑提供技术支持和理论支撑。
The static loading tests of cast-in-place two-way slab and double composite two-way slab are carried out to compare the stress differences of deflection and crack development of the two kinds of slabs under uniform load.Full-scale test shows that the mechanical properties of the cast-in-place two-way slab are basically the same as that of the double jointed two-way slab.It can be concluded that the deflection curve of double panel can be calculated by elastic sheet theory.This full-scale test provides theoretical basis for the revision of DB34/T 810-2008 Technical Code for Laminated Concrete Shear Wall Structure,and provides technical support and theoretical support for accelerating the promotion of prefabricated buildings.
