Experimental study on the effective width of flat slab

75 mm. The punching shear reinforcement at the corners of the slab consisted of 60 mm deep steel C-shapes. The C-sections were with stirrups of 6 mm diameter spaced 75 mm. Fig. 1 shows the geometry and reinforcing details. The average yield stress,/s, of the reinforcing steel was 467 MPa, while the aver­ age concrete strength was fc = 23.5 MPa Novel shearhead reinforcement for slab-column connections Jan 09, 2019 · Traditional means of reinforcing concrete flat slab-column connections against punching shear, such as increasing slab thickness, or provision of shear links, all have drawbacks. This paper proposes a novel type of punching shear reinforcement in the form of a shearhead to enhance connection strength and ductility.

Performance of ductile RC flat slab to steel column

This paper deals with the design of shearhead systems for connecting reinforced concrete flat slabs to tubular steel columns. ACI 318 [1] gives design guidance for fully-integrated ACI type shearheads, which is based on the work of Corley and Hawkins [2]. Various proprietary shearhead systems such as the Geilinger mushroom [3] are commercially Punching Shear Strength Characteristics of Flat Plate This paper presents an experimental investigation on the punching shear strength of reinforced concrete flat plate slabs with shearhead collars. Eight reinforced concrete slab specimens were casted and tested under static load test, the load was applied at the center of slab Reinforcement Detailing of Reinforced Concrete Slabs - The Thickness of the slab is decided based on span to depth ratio specified in IS456-2000. 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

Structural Integrity Requirements for Concrete BuildingsIn slabs where shearheads are used as shear reinforcement and it is not practical to pass the bottom bars required by section 13.3.8.5 through the column, at least two bonded bottom bars or wires in each direction must pass through the shearhead as close to the column as practicable and be continuous or spliced with a Class A US5181359A - Shearhead reinforcement - Google PatentsA shearhead assembly supporting a laterally extending concrete slab on a column wherein a shearhead is cast within the slab around the column, the shearhead comprising a hoop bar for extending around the column with a plurality of shear legs attached thereto and depending therefrom, each shear leg including a portion extending above the hoop bar, which portion forms a hook for coupling to reinforcement in the slab.

Shearhead Reinforcement for Slabs - Concrete

Date:10/1/1968. Abstract:Tests of concentrically loaded slab-column specimens containing either lightweight or normal weight aggregate concrete and shearhead reinforcement made from structural shapes are briefly described. Based on the results of tests on these 21 specimens, a design procedure for shearheads at interior supports is proposed
