Hi, I need to design pad footings in sand. The current design philosophy used in my workplace is to utilize skin friction as one of the methods to combat uplift in footings. The particular project I am working on has footings founded in sand, with a separate concrete slab pavement poured on top...

Hi, what would be the maximum allowable ground slope (longitudinally and transversally) under stacked shipping containers? I am trying to design rigid pavement (concrete) under stacked full containers and trying to find out the maximum acceptable slope before containers tip over. I looked in...

I am designing a structure that has 3 domes. I need to apply wind load on the domes to Australian Standard AS1170.2 Can someone please guide me to what's the best approach? If AS1170.2 does not clearly cover this situation, what alternatives can I use? I modelled the structure in Space Gass...

@ErieChch, can you please elaborate on the soil arching effect you mentioned? is it possible to sketch it so I can understand? thanks in advance.

Thanks @EireChch and @SlideRuleEra. I am assuming that there is no ground water at the moment. Also, I accounted for wheel loads to Australian Standards AS5100.2. I am also considering the stormwater pipe to be full. But my question in more related to the soil weight above the slabs. One of my...

I am required to design bridging slabs above a sewer line, as per the sketch below. The criteria is not to transfer loads to the sewer line, hence the need for a slab. the slab will be supported on 4 piers, so it is a suspended slab. My question is: how much soil weight does this slab carry? is...

Hi @Tomfh, I could not "see" settlement in the pathway. and the reo is a layer of SL82 mesh, so it is square, while the pattern is square/rectangular and much larger than the mesh grid.

Hi, I found the cracks shown in these photos in a concrete pathway. The cracks seem like a "grid-pattern", and also they seem to be perpendicular to sawn joints. Just wondering what can cause this pattern and why the slab would crack perpendicular to the sawn joint although the joints are places...

Hi, I need to calculate wind load on a vertical net between 2 floors in a building. The purpose of the net is to stop debris from flying off the building and divert it to the lower floor. Th net has a 42% Solidity ratio. My question is: Does the equation in AS/NZS 1170.2 clause D1.4 applies...

Hi All, I was tasked to design reinforced core filled masonry walls for loads I was given. The walls have axial compression loads and in plane bending moment. I can't find resources that explain how to design masonry walls against in plane bending moment to Australian Standards AS3700. Or at...

Hi All, Thank you very much for your much valuable help. I am very new to the forum and did not know how to mention each one by their name to thank each one individually. Very much appreciated.

Hi, I am tasked to design a ramp in a building. The ramp is supported by slabs at either end via corbels. The slabs are supported by walls at either sides. So the corbel is spanning between walls. I modeled the ramp using Inducta SLB Software, with line supports at the corbel locations to...
