Where can I find practice problems for "temporary structures and other topics"? (category for civil Pe exam.
I was only able to find some example problems but these topic is sprinkled and scattered so I'm trying to find
a good place to get more problems for this topic
I’ve been studying this topic and I know to use CH H formulas for combined forces of the AISC code it is pretty straight forward. However when a column size is unknown (in other words, designing for the lightest W shape for example) there are several procedures one can go about. I investigated...
Hi everyone. I was working on a problem from the IBC Structural /Seismic Design Manual and I have two questions I am wondering if anyone know, your answer would be appreciated. here goes:
1) when considering torsional and direct shear , is the torsional moment always assumed counter clockwise...
Hi everyone. I was wondering if anyone knows what is considered the "net shear area" in a masonry beam. I went through the current masonry code and searched online and it seems to be equal to An which is the cross sectional area. In other words Anv=An. however when im calculating the max...
Hi there. for corbel flexural reinforcement Af (moment) the PCI code example uses the following formula to find it
Af = [ Vu*av + Nuc*(h-d)] ÷ [ Φ fy d ]
and this is the formula I have been using ever since. But I recently bought a practice book online that states that Af is actually...
Hi there
I'm using the following formula from the AISC for the combined axial compression + moment
(a) when Pr/Pc ≥ 0.2
Pr/Pc + 8/9 ( Mrx/ Mcx + Mry/ Mcy ) ≤ 1.0
(b) when Pr/Pc < 0.2
Pr/2Pc + ( Mrx/ Mcx + Mry/Mcy ) ≤ 1.0
I have all the values ready to just plug and compute. The...
So I am calculating corbel reinforcement and I've gone through all the required ACI reinforcement equations ( Avf, An ) and am about to calculate As which is the primary reinforcement. In order to compute As, I need Af which is another reinforcement requirement established to resist factored...
So as I am calculating the compression load (design-LRFD)
equation as we all know is øPn = ø Fcr Ag
per the steel manual, AISC the value of the ø which is the resistance factor , is 0.90
but I am looking at 2 design book examples and they use 0.85 ! why ?
they are calculating the fcr...
Hi. I just wanted to make sure that I am interpreting this section of the code right. According to part (b)no strength test falls below f'c by more than 500 psi when f'c = 5000 psi or less, or by 0.10fc when fc is more than 5000 psi. in order for it to be satisfactory
So I came up with 2 simple...
I have researched this and I get mixed answers. But I would like to see if there's a simpler way to know which instances are best to use either pre-stressed or reinforced concrete in your practical expereince ?
If hypothetically I have a caisson that has:
1. a uplift force in kips , let's say of 100 k
2. and a gravity force in kips, let's say 75 k
knowing that these 2 force are NOT acting at the same time and also knowing the value of
1. the allowable soil skin friction (psf)
2. the allowable soil...
Hello. i am reading this section and just need clarification on section 8.3.3 part (b) that says " spans are approximately equal with the larger of 2 adjacent spans not greater than the shorter by more than 20% " . So for example having a 7 ft and 12 ft . How would I compute this? I just want to...
hello
am working on a standard 20 x 40 timber two-story. just need a general approach solution for where to put my shear walls on the right hand lower corner of the sketch. I re-drew the actual floor plan very simply for simplification purposes only. in the first pic (the pencil only one) i...
