“…The bottom reinforcement of the beam around the slab contains six rebars having a diameter of 16 mm and stirrups made of bars with a diameter of 8 mm and the spacing of 250 mm. The tank was deflected by 17.8 mm/m in the south-east direction, and therefore it was rectified [20]. For that purpose, stacks of concrete blocks were pressed into the ground under reinforced concrete beams which were part of the foundation.…”

The presented analysis concerns deflections of the reinforced concrete slab in the fire-fighting water storage tank with volume of 950 m 3 . It was built on human-altered soil which led to deflection of the tank. When water was pumped out from the tank, rectification was performed. The tank and its slab foundation were non-uniformly elevated by means of hydraulic jacks. These jacks were installed under the slab, on foundation made of concrete block stacks, which were pressed into the ground. The computational analysis was conducted for displacements and deflections of the slab supported on the jacks. The number of jacks under the slab and stiffness of jack supports on the stacks were the variable parameters of the model. Stiffness of the jack supports was found to have non-significant impact on deflections of the foundation slab of the rectified tank. On the other hand, the number of jacks under the tank affected both deflections of the slab and displacements of the whole tank. The greatest deflection of the tank slab supported on three jacks was 15.233 mm, and the smallest one was 10.435 mm at 32 jacks.

The use of Steel Fiber Reinforced Self-Compacting Concrete (SCFRC) as structural elements is seen as favorable alternative to solve typical issues of complex reinforcing spacing and compaction in normal reinforced concrete. The primary benefit of SCFRC is that it can be easily poured in-situ, filling corners of formwork and gaps between bars of reinforcement with its own weight. SCFRC's structural performance is constantly being investigated because of its superior engineering and mechanical properties. Steel fibers added to the mix improved the hardened properties of self-compacting concrete in terms of tensile strength, ductility, toughness, energy absorption capacity, and cracking resistance. This study reviews previous research on SCFRC performance in slab structures with an emphasis on flexural performance. Thus, the knowledge could provide guidelines for academia and industry players on the structural and materials behavior of the slab elements.

“…Besides, in the study of Allawi and Jabir [42], slab moment capacities increased and displacement values decreased as a result of the use of crossties in voided slabs. Wang et al [43], has observed that the slab strength and displacement capacities increase when steel fiber reinforced concrete is used.…”

The voided reinforced concrete slab system is mainly produced with polyester foam placed mostly at the bottom of the slab. The aim of the voids is to reduce the weight of the slab. In this paper behavior of the voided reinforced concrete slabs in which voids placed at the mid-height of the slab cross-section, is examined analytically. A series of models were created to come up with a lightweight slab. Two distinct slab models were analyzed using the ABAQUS software. In the first group, slabs had three layers, in which bottom and top layers were of solid reinforced concrete, but the mid layer was of voided unreinforced concrete. In the second layer, in order to increase the contact between top and bottom layers of the slab, crossties were utilized, and the mid layer was reinforced accordingly. Since all the layers were 5 cm thick, the total thickness of the slabs were 15 cm. Slabs were 100 cm wide and 200 cm long. They were simulated the three-point bending test. Concrete damaged plasticity material model (CDPM) for concrete and elastoplastic material model for steel was selected. From the results it was found that moment capacity decreased with the increase in the volume of the voids. There was a sudden decrease in strength after reaching the yield strength in voided slab without a crosstie. In addition, crossties enabled the reduction of the weight of the slabs without significant decrease in moment capacity.
