Da Inglese a Polacco: Strain and curving of the steel. Detailed field: Trasporti/Mezzi di trasporto/Navigazione
Testo originale - Inglese Checking for Web Buckling and Similar Limit States
The installation and alignment of the shape in the curving
machine are important considerations. These are very difficult
to have done exactly, since the actual support conditions,
the placement of the equipment rolls, etc., are rarely
known. However, the following checks should be made for
the shape by the structural engineer, as broad assessments of
the potential for local failures:
1. Web compression buckling (AISC Equation J10-8)
2. Web sidesway buckling (AISC Equations J10-6 and
J10-7)
3. Web crippling (AISC Equations J10-4 and J10-5a,b)
4. Web local yielding (AISC Equations J10-2 and J10-3)
The references to AISC give the equation numbers for the
respective limit states, as addressed in the AISC Specification
for Structural Steel Buildings, hereafter referred to as
the AISC Specification (AISC, 2005).
Of the preceding four checks, the web compression buckling
(No. 1) and web sidesway buckling (No. 2) are the ones
most likely to indicate a potential local buckling problem
associated with the curving of the shape. It is also noted that
the application of No. 1 to the curving of a beam is conservative.
In some actual cases, during curving at a bending facility,
web buckling has been found along with flange local bending.
The flange bending was a result of the too-small radius
and the phenomenon described earlier. However, the large
axial strain demands imposed by the curving operation and
the web buckling were the driving forces, eventually having
caused the fracture of the web or the flange by throughthickness
bending. Flange and web restraints might have
eliminated these problems.
It has been noted that shapes with a larger web thickness
tend to perform better during the bending operation. The
increased web thickness provides a higher buckling strength
and hence less opportunity for transverse flange bending to.
Traduzione - Polacco Sprawdzanie wyboczenia srednika i podobne stany graniczne
Instalacja i dostosowanie kształtu w maszynie zakrzywiającej są istotnymi rozważeniami. Są to warunki bardzo trudne do dokładnego spelnienia, ponieważ rzeczywiste warunki wsparcia, umieszczenie rolki sprzętu itd., są rzadko znane. Jednak należy dokonywac specyficznych kontroli przez inżyniera budowlanego, oceniając doglebnie możliwy potencjał lokalnych awarii:
1. Kompresja wyboczenia srednika(AISC równań J10-8)
2. Wyboczenia drogi bocznej srednika(AISC Równania J10-6 i
J10-7)
3. Srednik wyniszczający (AISC Równania J10-4 oraz J10-5a, b)
4. Odksztalcenie srednika lokalnego (AISC Równania J10-2 oraz J10-3)
Odniesienia do AISC podaja numery odpowiednich stanow granicznych, jak pisze AISC Specyfikacja
Strukturalna Hal Stalowych, zwana dalej AISC Specification (AISC, 2005).
Na podstawie czterech poprzednich kontroli, kompresja wyboczen srednika (Nr 1) i wyboczenia drogi bocznej srednika (nr 2) są najczęściej wskazywane jako potencjalne lokalne problemy wyboczenia
związane z zakrzywieniem kształtu. Należy również zauważyć, że wniosek nr 1 dotyczacy zakrzywienia belki jest konserwatywny.
W niektórych obecnych przypadkach, w czasie zakrzywiania na terenie obiektu gięcia, stwierdzono wyboczenia srednika wzdłuż zgięcia lokalnego kołnierza. Zgięcie kołnierza powstalo w wyniku zbyt małego zasięgu promienia i zjawiska opisanego wcześniej. Jednak duża osiowa wymaga nałożenia sil napedowych na operacje funkcjonowania krzywej i wyboczenia srednika , ewentualnie powodując złamanie srednikalub kołnierza poprzez zginanie. Uzycie kołnierza i ograniczenie srednika mogą wyeliminować te problemy.
Stwierdzono, że kształty z większą grubośca srednika wykazują większą skuteczność podczas operacji gięcia. Zwiększenie grubości srednika zapewnia wyższą wytrzymałość wyboczenia oraz mniej okazji do poprzecznego zgięcia kołnierza w miejsu.

I am a Polish native English and Italian translator since 1996.
I believe that I am a reliable and trustworthy person. As I constantly try to improve my translation skills, I am available seven days a week, from 9 a.m. till 10 p.m. I have a DSL internet connection and use an automatic system notifying me of every new email in my hotmail e-box. I daily translate from 1200 to 1500 words (or more) depending on the subject matter of the text. I accept payment via Moneybookers, Pay Pal and Western Union. I hope you will be interested in my services.
