Hi all, Can someone provide me with a source, software, or spreadsheet than could design a layered concrete slab? I did model it on etabs (one layer old over a new one) but I have some concerns about shear forces between the layers and how reinforcement shall be checked.

Hi all, I'm having a trouble in exporting slab load from etbas to safe... actually the error im getting is "error in exporting loads from above" when i check the loads exported, all the loads have forces results on the slab except the modal response spectrum loads (Seismic Ex and Ey). noting...

Hi all, I was checking the etabs effective seismic weight. I choose the masses only for the self weight of the structure. etabs calculated the bas shear using part of that mass.any ideas? picture are attached below. https://drive.google.com/folderview?id=11iuGGHDzzMhyXDCcV6iOzXA4NLY18NvK

Hi all, I Hva and existing deep beam with a section of 20x60 cm . the existing bottom steel is 2 T16 which is below the minimum required reinforcement by 20%. (must be 2T20). I am adding a load on the beam, but the issue is the following. The beam without any additional steel can support the...

Hi all, I have an old building rehabilitation. can anyone suggest a book od a reference regarding retrofitting structural design..column concrete jacket, beams and others. I already have retrofitting design; f building structures but it's based om Chinese code..I need a similar reference based...

Hi all, I was designing a beam using RSA when w faced a huge minimum area of reinforcement at zero moment (attached screen shot) I didn't find any clue in ACI mentioning this huge increase of As,min . the beam dimension is 90x30 cm. Can someone clarify me why Im getting this...

Hi, ACI 314 mention a limitation for girder width to column dimansion. Is there any limitation mentioned in 318? Or this is only a purpose due to the simolification in 314?

I was searching for a handbook to design concrete and steel jacket for columns and beams. Any idea?

Hi all, I have a questions about minimim ties and stirrups diamter. ACI 318 mention that the minimum diamter to be used is 10 mm. In my country, we always use 6 and 8. Because it's easier to be bent on site. But my question is do ACI 318 or any other code in old revisions accepts these small...

Hi all, I was reading ACI 314R-11, It is specified that the minimum column dimension is 250 mm or the vertical distance between lateral supports over (10 ,9 or 8, depend on location). When I rechecked ACI 318 I didn't notice any note regarding this issue. Note that for a 2 story building with 3m...
