The initial conclusion is that in some situations for calculations of anchorage capacity of a rebar Robot attributes a rebar in tension as being under compression. Eurocode 4: Bemessung und Konstruktion von A number of laboratory experiments on shear capacity of pile caps have been carried out in the last five decades. Nominal Shear Strength. Each internal point is NOT automatically treated as a support. Ultimate axial force on column V Ed = 400 kN Thickness of slab = 250 mm Dimension of column = 450 x 230 mm Reinforcement of slab in the longer direction = H16@150mm (A s,prov = 1340 mm 2) Reinforcement of slab in the shorter direction = H16@175mm (A s,prov = … It presents the principles of the design of concrete ele-ments and of complete structures, with practical illustrations of the theory. Strengthening an existing concrete structure through the use of shear dowels is a primary application of post-installed rebar. Like BS 8110, EC2 models shear behaviour on the truss analogy Shear load capacity for reinforced concrete slabs verification according to Eurocode (EN 1992-1-1:2004) Available languages: English, Italian, Croatian Available norms: EN 1991-1-1:2004 UNI EN 1992-1-1:2004 - Italian NA. Eurocode 8-2004 . In the Eurocode model, a simplification is made such that once cracked, the section shear capacity comes solely from the links. The authors explain the background of the Eurocode rules and go beyond the core topics to cover the design of foundations, retaining walls, and water retaining structures. The deck carries a 100mm depth of surfacing, together with a traffic load (LM1) udl of 5.5 kN/m 2 and tandem axle load of 100kN (300kN/3m lane width). ... my humble opinion is that Eurocode 2 is wrong about longer compression vs tension ... but which from Robot I got warnings concerning insufficient capacity for moment and shear. where bw = the beam width or the minimum width of the stem. Note that for a physical member to see a support, there must be a point at that support point.If a physical column and a physical beam cross each other without a joint at their intersection, then no support / span will be detected and t… Eurocode 2 and fib Model Code 2010 (MC2010) account for this by reducing the design shear force, unlike the previous UK code BS 8110, which I have seen values from 0.5 to 0.75 Fy used,so my 0.6 seems a safe middle value, but for the life of me can find no reference to where that comes from. The deck should also be designed to carry the SV80 model vehicle. According to the Eurocode 3 (steel structures), these webs of the steel deck have their own transverse shear capacity, which is neglected by the current design approach defined in the Eurocode 4. The nominal shear strength (Vn) is composed of the sum of However, the BS EN 1992-1-1 model allows the designer to select the angle of the compression strut (θ, Figure 5), with a flatter strut leading to more links being intersected, thereby increasing shear capacity. 6.4.3 Punching shear calculation 6.4.4 Punching shear resistance of slabs and column bases without shear reinforcement 6.4.5 Punching shear resistance of slabs and column bases with shear reinforcement 6.5 Design with strut and tie models 6.5.1 General 6.5.2 Struts 6.5.3 Ties 6.5.4 Nodes 6.6 Anchorages and laps 6.7 Partially loaded areas If the applied shear force exceeds the capacity, the stirrup requirement is computed. roughness to stiffness and capacity in shear. The shear force carrying capacity of the section without shear reinforcement is determined for both directions from Clause 6.2.2 of EC2. The Hilti HIT Rebar Design Method takes advantage of this increased bond strength in order to achieve anchorage length reductions of up to 70%, ... Punching shear reinforcement. The shear force that can be resisted is the shear stress x cross section area: V c = u c x b w d. The shear stress for beams (one way): so . φ = 0.75 for shear However, the BS EN 1992-1-1 model allows the designer to select the angle of the compression strut (θ, Figure 5), with a flatter strut leading to more links being intersected, thereby increasing shear capacity. For ETABS ® 2016 . ISO ETA122815M44 Rev. Design for Shear. Shear Wall Design Manual . Instead, we go through the whole model geometry to determine where a beamor column is supported. The value of φ applies when both the load combinations of ACI 318 Section 9.2 are used and the requirements of Section D4.4(c) for Condition B are met. But at Hilti we’ve gone even further. 3. 0. The basic design equation for shear says that the reduced nominal shear capacity must be greater than the factored shear force. Thus, this report aims to analyse and evaluate the comparison of shear capacity of reinforced concrete beams without shear reinforcement against experimental beam data using Eurocode 2 and BS 8110. General shear design A summary of relevant codes of practice and how they deal with concrete in shear 4. the current Eurocodes. Clarke [3] tested fifteen full size reinforced concrete pile caps, each with four Punching shear proof. recommended by the Eurocode; values to be used may be found in the Eurocode National Annexes Design compressive concrete strength per EN 1992-1-1:2004 Section 3.1.6 & Formula 3.15 a cc = Coefficient taking account of long term effects f cd = a cc * f ck / g c = MPa
