Hi Team,
I am working on a bridge deck problem where the shear capacity of the deck is highly utilized at ULS (~95%) and the flexural capacity utilization is less significant (~65%). In steel analysis, shear/flexure interaction is considered and flexural capacity is reduced if shear demands...
Hi EngTips team,
How do people interpret the (LL x I = 2.25) and (OL x I = 1.49) load factors in table 3.2 of the New Zealand Transport Authority Bridge Manual (SP/M/022)?
For ULS cases:
is a designer supposed to multiply I to 2.25 for an HN load or does the 2.25 value include the 1.3...
Hi EngTips team,
SOME BACKGROUND:
In a pony portal, the top chord acts as the main compression element resisting vertical loading. The bottom chord acts as the main tension element. The internal (vertical and diagonal) members, of each truss, act to transfer loading to achieve equilibrium...
Hi Eng-tips,
I have a question concerning the barrier loading requirements specified in SNZ HB 8630 (Tracks and Outdoor Visitor Structures).
Clause 3.6 outlines the "Ulitmate limit state for barriers" loading.
In clause 3.6.1, table 10 provides the "Basic live load" on the barrier of a...
Thanks, Steveh49 and gusmurr.
@Steveh49, in the attached document, b is referred to as the "width of the concrete flange in the composite section". Do you believe that this means we simply take the tributary width or still use Cl 4.4.1 as gusmurr has suggested?
Hi Eng tips community,
I am working through the design of a composite beam bridge using AS 5100.6 - 2017. I understand how I would derive the capacity of a 'non-compact' composite cross-section but I am having difficulty deriving the capacity of a 'compact' composite cross-section.
Clause...
