Flexural Strength Evaluation of Reinforced One-Way Concrete Slab With Plastic Voided Inserts
Experimental tests of bending reinforced concrete slab have shown that flexural strength of reinforced concrete voided slab with hollow plastic inserts is lower than flexural strength of continuous cross section slabs (solid slab). Investigation of experimental data from science publications illustrates that difference of strength between voided slab with plastic hollow inserts and similar solid slabs can vary, from 3% to 27%. During the experiments was evaluated, that variation of flexural strength depends on lots of factors as: plastic void's shape form, installed quantity of plastic elements in the slab, distance between plastic voids, ratio of plastic hollow void’s diameter with the slab's height. Meanwhile flexural strength evaluation methods, as EC2 do not take in account of influence of plastic voided hollow inserts in the calculation of flexural strength. Therefore, was made analytical calculations according to experimental bending tests of voided reinforced concrete slabs with plastic hollow inserts to find and propose corrections for evaluation of flexural strength of reinforced concrete voided slabs with plastic hollow inserts.
