Thanks for all of the great responses guys. I'm on the road at the moment so won't be able to provide a sketch. However, what I've got is an EXISTING 390mm x 190mm Unit Concrete block wall. The owner wants to essentially bolt a rack of powerlifting weights (see picture below). I want to...

So basically I should be right just checking the moment generated by this object vs the moment capacity of the wall. Is there anything else in particular that I should be looking st?

The Australian code AS3700 gives design guides for both verticle and horizontal bending i believe

My apologies, it's pretty much an eccentric load acting on wall

Hi Guys, Ive got a blockwork wall 4 meters in height and its supported a 3 tonne object bolted into the side of the wall at half its height. I'm guessing this will place quite a large concentrated moment onto the wall. I'm not 100% sure about how to go about designing this wall to deal with...

Hi guys, Was hoping someone could shed some light on horizontal vs vertical bending of brick walls. I'm guessing if you had a wall that's restrained too and bottom then you would probably only need to design for horizontal bending of the brickwork. When would you look at both horizontal and...

Thanks for the responses all. Nice sketch by you kootk. So let's say the bottom cord is twice as stiff as the perimeter beam in the minor sxis, am I right to assume it will take twice the load? Bowling danish, good idea mate, that's pretty much what I went with.

If I had a truss sitting on a beam and the truss purely only had dead load, there shouldn't be any horizontal load even though it's pinned st each end to the beam. However in theory, if you modelled this there would be horizontal loads unless one end is s roller. Am I right in saying this ?

Thanks hokie, appreciate the response mate.

Thanks for that Hokie. Yes, that's what i was thinking. I was wondering how i could prevent this cracking as the only way to reinforce this type of brickwork is centrally. Just in terms of checking the strength of the actual connection, is it as simple as calculating the shear capacity of the...

Yes, i do need to get moment into the footing. But my question is; will a single reo bar in the center of the wall do that? Thats the standard detail my office uses for these walls but i just dont understand how this is transferring moment...

Ok thanks Hokie. Well what ive got is basically a brick fence only designing it for wind pressure. Isn't the cogged length purely just to get the desired development length of the reo?

Sorry my mistake... Its a cantilevering wall. Im trying to say doesnt the wall to the footing need to be a moment connection in order to transfer the moment?

Hi guys, i was hoping someone could help me get my head around the connection from a masonry wall to a strip footing. I've noticed that its quite typical just to extend the masonry reinforcement down into the footing and to cog it by 200mm or so. My question is, as this reinforcing bar is...

Can anyone shed some light on why there is a reduction in strength to the reinforcement component in the shear design check for masonry in the AS3700?

You make a good point jayrod. Thanks mate. Sorry, which compressive force were you referring to and what exactly to you mean by truss action?

Hi guys, Quite new to the engineering game and am a little unsure as to how the certifying process works. Let's say i design a job but another RBP signs off on the job in order to get the building permits, does the person who signed off on the job take 100% responsibility for the design if...

Yes that's correct RB1957. Will most likely be 450 dia bored piers for the footings.

Thanks for the response Hokie. I totally agree with you and that would be my preference also. Unfortunately, this is what the architect wants so ill have to do my best to make it work.
