[PDF] Performance of ductile RC flat slab to steel column pdf shearhead reinforcement for concrete slab to Milling

Abstract This paper is concerned with the performance and design of a novel ductile structural steel shearhead for connecting reinforced concrete flat slabs to tubular steel columns. In the suggested system, a gap is left around the column to enable the slab to be connected to the column through isolated structural steel members which are designed to yield in shear before punching failure occurs.Which is Guide to shear reinforcement for slabs?ACI 318 sets out the principles of design for slab shear reinforcement and makes specific reference to stirrups, headed studs, and shearheads. This guide reviews other available types and makes recommendations for their design. The application of these recommendations is illustrated through numerical examples.See all results for this questionWhich is ASTM for headed shear stud reinforcement?Section 11.11.5 of ACI 318-08 permits headed shear stud reinforcement conforming to ASTM A1044/A1044M.

When to use shear reinforcement in stirrups?

Section 11.11.3 of ACI 318-08 allows the use of shear reinforcement for slabs and footings in the form of bars, as in the vertical legs of stirrups. ACI 318 emphasizes the importance of anchorage details and accurate placement of the shear reinforcement, especially in thin slabs.See all results for this questionThe Repair and Protection of Reinforced ConcreteTHE REPAIR AND PROTECTION OF REINFORCED CONCRETE WITH SIKA IN ACCORDANCE WITH EN 1504 CONCRETE REPAIR AND PROTECTION The European Standards EN 1504 consist of 10 parts and is a systematic approach to rehabilitating concrete.

REINFORCEMENT HANDBOOK - Structural Engineers

Aug 02, 2012 · Reinforcement includes deformed bars, plain bars, wire, fabric and steel products, all of which increase the tensile and compressive stress carrying properties of concrete. Steel reinforcement is also the essential contributor towards crack control of concrete structures. Reinforcing Bar A bar is a finished product rolled to close tolerances.Punching Shear Failure of Reinforced concrete flat slabs pdf shearhead reinforcement for concrete slab to Milling= bending stiffness ratio between the shearhead and cracked concrete. æ = Thickness of slab = second moment of area of concrete æ = second moment of area of steel. Slab 1= slab without shear reinforcement Slab 2 = slab with shearhead ì = yield strength of steel ë = strain in the x- direction ì = strain in the y- directionPunching Failure of Reinforced Concrete Flat Slabs at Edge pdf shearhead reinforcement for concrete slab to MillingAn experimental and analytical investiagation of the punching shear capacity and moment transfer characteristics of reinforced concrete flat slabs at the edge column location is presented. In all, 12 models with carefully controlled boundary conditions were tested. Six of these were used to investigate the effect of column aspect ratio and size on the punching shear capacity.

This paper proposes a novel type of punching shear reinforcement in the form of a shearhead to enhance connection strength and ductility. The structural behaviour of the connection is explored MODELLING AND EXPERIMENTAL ASSESSMENT OF The slab was vertically restrained by 16 ties positioned around its perimeter as shown in Fig. 1. The tensile reinforcement consisted of T16 bars at 90mm centres in each orthogonal direction. The compression reinforcement consisted of T10 bars at 180mm centres in each orthogonal direction. The mean concrete cube strength was f cu =30MPa.

How to evaluate punching shear strength of slab columns?
