Hi
I have a case which the rafter has webside plate (weld to the web of the rafter, the length of the plate is approximate half of the depth of the web from the bottom of the top rafter) bolt (two bolts) to the purlin at 0.9m spacing. the bolt hole is slot hole (2.5 x the bolt dia) instead of...

Hi Guys
I am designing some frame structures to support some big signs next to the HWY.
The frame is a 2D structure, supported by 2 posts, and I would like to see is there any deflection requirements of these posts (any code?). The result I have is approx. H/100, and I accpected this result...
Hi guys
When we design piles(fully submerged in ground)in bending, do we still need to consider the crack control in serviceability limit state (AS2159 CL5 doesn't mention)? If yes, why? In my understand, the crack control (AS5100.5, CL8.6) limiting the reo stress is used to control the crack...
Hi
Just a question, in the code, it stated the y1 is the larger core dimention of a closed rectangular tie. What happen if it is circular tie for circular column?. y1 is equal to the diameter of the tie? It just came up a very close spacing then.
Thanks
Hi
I have a question about the longitudinal design shear strength.
The application in AS5100.5 stated, this clause also applies to the transfer of shear across any specific interface such as between precast and in situ concrete or across construction joints.
So my question is, now, I am...
Hi
Can anyone teach me how to find out the maximum moment at plastic hinge of the pile in pile group.
My case is, my abutment has 2 rows of pile spacing 1000mm, all piles size 400mm x 400mm. there are 4 piles each row(spacing 3m, 2.4m, 3m). The abutment beam is 1.9m wide x 1m depth. The...

Hi
I have a question here, a builder build a single span one way slab himself, the slab is 150mm, and he placed one layer main reo bar at mid of slab. But it is not strong enough to take the design loads. So he is thinking adding some internal supports.
Can any one see if it is workable? from...
Hi everyone
I am a new engineer in Australia, sometimes I see the bridge drawings shows there are some rock anchors in the spread footing of the pier, and would like to ask what is the purpose for this? In my understand, the pier only resist axial loading, and in the model, the base of the pier...
Hi All
Is it worth while to be a CPEng?
I have almost three years structural engineering expriences since graduated, these days, all my Uni friends talking are about chartered status application (make me feel sick that every time talking to them, the first question almost is "how is going of...
Hi Fellows
I am from Australia, I am doing a bridge rehabilitation project. The original design is from the Main Road Board in 1929. It doesn't show the grade of reinforing & concrete on the drawing.
So my question is, in 1929, what is the common reinforcing and concrete grade? (in MPa)...
