# 1 Wonderful Punching Shear Calculation Spreadsheet Eurocode

root. Spreadsheet. October 03rd , 2020.

22 february 2008 1 eurocode 2: Critical section for two way shear (punching shear) hence, punching area of footing = (a + d) 2 = (0.45 + 0.442) 2 = 0.796 m 2 where a = b = side of column.

### An example is the calculation of the load increment factor β based on the model with fully plastic shear force distribution in the control perimeter, or the iterative calculation of the basic control perimeter area of.

Punching shear calculation spreadsheet eurocode. The slabs supported directly on columns, without beams between columns. General rules and rules for buildings. Punching shear perimeter bs 5400 part 4.

The procedure for determining the punching shear requirements is shown in figure 4. All sheets are authentic and established in according with aci318, bs8110, eurocode 2 and as3600. The minimum reinforcement area a s,min;

Spreadsheet tcc81 from spreadsheets for concrete design to bs 8110 and eurocode 27). Its content is under intensive development so check regularly, or subscribe to the newsletter, to stay up to date with the latest releases. Structural design calculations according to eurocodes.

These excel sheets are the solutions to the problems. Punching shear punching shear symbols ui = ith perimeter. Outside the u 1 perimeter the link.

Spreadsheets for design to bs en 1991. 6.4.5 (1) punching shear resistance of slabs and column bases with shear reinforcement, v rd,cs; Eurocodeapplied.com is a free online service that civil engineers can use to perform structural design calculations according to the latest eurocodes (en1990 to en1998) and the associated european norms (ens).

This paper compares design provisions for punching shear at internal columns in the superseded british standard bs8110, eurocode 2 (ec2) and fib model code 2010 (mc2010). 7.3.4 calculation of crack widths w k (3) an appropriate design model for checking punching shear failure at the ultimate limit state is shown in figure 4.16.

Alternatively, a spreadsheet could be used (e.g. Therefore, provide a minimum area of reinforcement. Check for maximum shear consider 1.0d form face of the column design shear force = 216*2.9*0.798 = 499.9kn as above v rd,c @ 1.0d = 0.4*1000*452 = 180.8kn < 499.9kn hence, shear reinforcement is required.

The provisions for punching shear design according to eurocode 2 cannot be applied efficiently without a software solution. On this website you will find excel spreadsheets for architects, contractors, civil and structural engineers (professionals and students). Punching shear perimeter as per eurocode 2.

Excel® file +.doc linked file (calculation report) Within the u 1 perimeter the link spacing around a perimeter, s t ≤ 1.5d = 1.5 × 213 = 319.5 mm. 3,0 30 0.32 1642 204 10 390 kn 661kn 1.5 ck rd c v d c f vk bd v punching strength with shear reinforcement firstly, one has to check if the design shear force v d is smaller than the

Shear capacity, vc = 0.532 n/mm 2. International consensus had to be reached, but not on the cost of significant concessions with regard to quality. V rd,c = design value of punching shear resistance of a slab without punching shear reinforcement, expressed as a stress (see shear table 7) v rd,cs = design value of punching shear resistance of a slab with punching shear reinforcement, expressed as a stress.

As per bs 8110 part 1 table 3.16, vc + 0.4 = 0.532 + 0.4 0.932 n/mm 2. Punching strength without shear reinforcement the punching shear strength of the concrete is not sufficient. Normally, shear reinforcements are not provided for pad footings.

Spreadsheet could be referred to simply calculate the reinforcements and shear links. V rd,cs = 0.75 v rd,c + 1.5 (d/s r)a sw f ywd,ef (1/u 1 d)sin a. Hence, punching shear is ok.

Consequently, shear reinforcement is necessary. Distance to punching shear perimeter is 1.5d in bs 5400 whereas it is 2d in eurocode 2. Vc < v < vc+0.4.

U1 = basic control perimeter at 2d u1* = reduced basic control perimeter u0 = column perimeter d = average effective depth k = coeff. Slab punching design models are presented according to eurocode 2, aci code 318, and fib model code 2010. Punching strength of flat slabs with and without shear reinforcement the punching shear strength is an extremely significant parameter for the design of flat slabs, i.e.

The latter is based on the critical shear crack theory (csct) of muttoni which The method of calculating the punching shear in the solid slab is given in the bs 5400 part 4 1990 and has a slight difference when compared with eurocode 2. Provide 7h10 (a sprov = 549 mm 2 per perimeter).

Detailed design rules may be offered, consuming more calculation time, but resulting in more accurate and economic results. Vrd,c resistance of members without shear.
