What Is Main Bar And Distribution Bar In Slab? [Civil
a) Slab depth does not exceed 250mm when the steel grade is 250. b) Slab depth does not exceed 200 mm when the steel grade is 460. c) Slab reinforcement percentage less than 0.3% (100As/bd < 0.3%. When above a, b, and c conditions do not apply, bar spacing shall be limited as following Table (Table 28 of BS 8110 Part ) where the reinforcement.

Minimum reinforcement is 0.12% for HYSD bars and 0.15% for mild steel bars. The diameter of bar generally used in slabs are: 6 mm, 8 mm, 10 mm, 12mm and 16mm. The maximum diameter of bar used in slab should not exceed 1/8 of the total thickness of slab. Maximum spacing of main bar is restricted to 3 times effective depth or 300 mm whichever is.

Q) Design a reinforced concrete slab for a room of clear dimension 4-meter x 5 meters. The slab is supported all around walls of width 300 mm. The slab has to carry a live load of 4 KN per meter square. and floor finishes 1 KN per meter square. Use M20 Concrete and 415 steel. assume corners are held down. Sketch the detail of reinforcement.

Common Methods of Detailing Two-Way Slab Reinforcement Two-way slabs are generally defined as suspended slabs whose ratio of long span to short span (bay length to width ratio) is less than two. Section 13.1.1 of ACI 318-111 identifies a two-way slab as a slab system designed for flexure in more than one direction. Normally, it is assumed

The East (Section 5-5) and North (Section 3-3) walls are shown in cross section. The column footing and pier reinforcing bars are shown in schedules. In drawing wall elevations where footing steps occur, the detailer refers to the "Typical Stepped Footing" detail on the structural drawing and footing elevations on the plan view.

As can be seen from the figure-2 below, the tension reinforcement are 100% at the mid-span of the beam and slab, while it is curtailed at the distance of 0.1 L from the center of the support at end support and 0.2L at the intermediate support. L is the effective length of the beam and slab. The shear reinforcements are provided from the support.
