Hi dears!welcome backhere in this presentation we will be learning the detail process of designing a one way reinforced concrete slabin this tutorial 1st wA suspended concrete floor is a floor slab where its perimeter is, or at least two of its opposite edges are, supported on walls, beams or columns that carry its self weight and imposed loading The floor spans between supports and will normally deflect under load to a dimension that is limited by the design usedThis sounds like an unauthorised structure that had minimal reinforcement Ideally, you should vacate the structure right away, and demolish the building The next best thing as a temporary fix is to have multiple steel beams with plates welded to

Reinforced concrete suspended floor slab
Reinforced concrete suspended floor slab- Suspended slabs are normally sat on hardcore or some barney rubble or something The design means that if the ground settles away under the slab afterwards then it doesn't matter because the slab is capable of spanning across the supports A sus slab isn't such a big deal but I would be uncomfortable not designing it properly and for that you(2) to determine the level of imposed load that can be sustained;

Suspended concrete slabs are generally constructed in two ways * Precast The slab is constructed in forms elsewhere;This chapter gives guidance on meeting the Technical Requirements for suspended ground floors including those constructed from insitu concrete precast concrete timber joists 521 Compliance 522 Provision of information 523 Contaminants Floor beams in a reinforced concrete building are normally designed to resist load from the floor slab, their own selfweight, the weight of the partitions/cladding, the weight of finishes, and other actions as may be applied The design of a reinforced concrete (RC) beam involves the selection of the proper beam size and area of reinforcement to carry the applied

A suspended floor is a ground floor with a void underneath the structure The floor can be formed in various ways, using timber joists, precast concrete panels, block and beam system or cast insitu with reinforced concrete However, the floor structure is supported by external and internal walls Similarly, how do you make a solid ground floor?Consideration of vertical and lateral main building movement (storey drift) of the existing RC suspended floor slab at lower P2 and upper P5 level over the short and long term as a result varied the spring stiffness of the supports in Global model Energy consumption in accordance with Dubai Municipality Regulations (decree 66) for the design and air conditioning of the enclosureOnce completed and cured it is put in place by cranes or jacks, then suspension components are attached This includes liftslab

A suspended concrete floor is a floor slab where its perimeter is, or at least two of its opposite edges are, supported on walls, beams or columns that carry its self weight and imposed loading The floor spans between supports and will normally deflect under load to a dimension that is limited by the design used The prestressing of a concrete floor slab can eliminate its usual deflectionTableform/flyingform A table form/flying form is a large preassembled formwork and falsework unit, often forming a complete bay of suspended floor slab It offers mobility and quick installation for construction projects with regular plan layouts or long repetitive structures, so is highly suitable for flat slab, and beam and slab layoutsThe concrete floor slab system shown below is for an intermediate floor to be designed considering partition weight = psf, and unfactored live load = 40 psf Flat plate concrete floor system does not use beams between columns or drop panels and it is usually suited for lightly loaded floors with short spans typically for residential and hotel buildings The lateral loads are
