Abstract To study anti-bending properties of pacting concrete dual-way slabs six pacting and two
��
corresponding ordinary concrete dual-way slabs of two different strength grade are made. The results show that 1 the
experimental data of limit load of pacting concrete dual-way slabs are close to those of the ordinary concrete
, ��
dual-way slab with same strength grade and are obviously higher than their theoretical value 2 the load-deflection
