Experimental study on the mechanical behavior of precast reinforcement truss cement fiberboard
At present,the prefabricated floor slab is mainly applied to composite floor slab in China,and the use of prefabricated steel truss cement fiber board has not been popularized.In this study,the failure mode,bearing capacity and deformation capacity of two prefabrica-ted steel truss CFRP slabs of the same size are investigated by using the traditional static surcharge method.The results show that the prefabricated steel truss CFRP meets the de-sign requirements of the ultimate bearing capacity state under the construction conditions;the maximum deflection in the middle of the span is about 2.61 mm and 2.77 mm,which is far less than the calculated value of deflection and meets the limit requirements of relevant specifications.It shows that the prefabricated steel truss cement fiber board has good bearing capacity and overall deformation capacity in the construction stage and can be used as the bottom formwork of the composite floor.
