formulas for predicting strength of

formulas for predicting strength of unstiffened webs and
stiffened webs with full-depth stiffeners under local compressive
loads, it does not have any formula to predict crippling
strength of webs with partial-depth stiffeners under
local compressive loads. Research on the behavior and
design rules of intermediate transverse stiffeners attached
on web panels was summarized by Lee et al. (2002, 2003).
Research on the requirements of transverse stiffeners in
straight and horizontally curved steel I-girders was summarized
by Kim et al. (2007). Research on unstiffened webs
under compressive edge loads was summarized by Elgaaly
(1983). Research on the same topic post-1983 was summarized
by Salkar (1992) at the University of Maine.
This paper highlights part of the research at the University
of Maine and gives recommendations based on the results of
this research. This paper also presents a brief comparison of
provisions of the 2010 AISC Specification, Canadian codes
(CSA, 2006) and Australian (AS, 2012) codes with respect
to crippling strength of stiffened webs under local compressive
loads.
This paper addresses the strength of stiffened webs of
rolled shapes under local compressive patch loads between
supports. Three types of local compressive patch loading
have been considered:

Hierdie vraestel Hoogtepunte Deel van die navorsing aan die Universiteit
van Maine en gee aanbevelings gebaseer op die resultate van
hierdie navorsing. Hierdie vraestel bied ook 'n kort vergelyking van
bepalings van die AISC spesifikasie 2010, Kanadese kodes
(CSA, die 2006) en Australiese (AS, in 2012) kodes met betrekking
tot verlammende krag van verstyf webbe onder plaaslike druk
