Abstract [sv]

Datoriseringen av samhället har inneburit att datorn har blivit ett självklart hjälpmedel för

att utföra avancerade arbetsuppgifter. Konstruktörer gjorde tidigare åtskilliga

handberäkningar för att dimensionera byggnadsverk, vilket numera görs i datorprogram.

Kunskapen om teorin vid beräkning behövs därför inte i samma utsträckning. Efter

indikationer från erfarna konstruktörer kan det finnas ett behov att jämföra aktuella

beräkningsprogram med gällande Eurokoder.

Syftet med det här examensarbetet var att beräkna genomstansningskapaciteten i armerade

bjälklag samt att utforma eventuell skjuvarmering. Arbetet avgränsades till att omfatta en

innerpelare i ett betongbjälklag med cirkulärt tvärsnitt utan pelarkapitäl eller förstärkningar.

Metoden var en teoretisk studie av eurokoderna. Nio olika fall beräknades genom ett eget

framarbetat beräkningsark i Mathcad, enligt gällande eurokoder. Resultatet jämfördes sedan

med Winstatik Punching och caeEc230.

Beräkningsarket, Winstatik och caeEc230 hade likvärdiga resultat både gällande

kapaciteten i pelarens periferi och kapaciteten i grundkontrollsnittet. Störst olikheter fanns i

utformningen av skjuvarmeringen. De visade liknande mängd armering uttryckt i area, men

ingen vägledning vid utformning. CaeEc230 föreslog omkring dubbel mängd armeringsskär

än beräkningarna i Mathcad. Winstatik Punching redovisade inget totalt antal.

Abstract [en]

Computers have become invaluable for advanced calculation tasks in most industries.

Formerly, designers had to rely on his skills and knowledge to perform calculations.

Nowadays, designers can execute a calculation without the need to use the actual formulas

behind. It is recommended by experienced designers that some of the programs used in the

building industry, which are based on the European Eurocodes needs to be validated.

The aim of this study has been to calculate the punching capacity of ordinary reinforced

slab and to design the shear reinforcement, according to Eurocode 2. The method was a

theoretical study of the Eurocodes. A calculation sheet for punching capacity was made in

Mathcad. The calculations from the sheet were compared to Winstatik Punching and

caeEc230. The work has been defined to include only an inner column on a concrete slab

with a circular cross section without any column heads or other reinforcements. In order to

achieve realistic calculations, nine cases with different slab thicknesses and spans were

manipulated.

The capacities from the three calculations were nearly identical, both at the columns

perimeter and at the control perimeter. The greatest differences were found in the design of

the shear reinforcement. They showed similar amount of reinforcement in terms of area, but

offered no guidance on the design. CaeEc230 suggested about double the amount of rebar

cuts than the calculations in Mathcad. Winstatik Punching reported no total at all.
