    Attaching wood frame to finished concrete

    After the typhoon stress test some weak spots became apparent. One of them is the second floor open terrace. The terrace is around 4x4 meters, on two sides walls and two sides open so one corner column, then high wall like 1m+ parapet which was made like that for safety because of children. On...

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    It looks like there is no column there as well. So those are all plastering issues then. Thanks for clarification.http://files.engineering.com/getfile.aspx?folder=f4832d0e-e103-43e5-bd22-7c69dd214461&file=plastering.jpg

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    Yes, the first three pictures it is what I meant. As to the topmost floor it looks like the same pattern was present, there is a painted patch job (encircled yellow), there is other patch work visible on the building, so it is likely the topmost floor is where it appeared first and then it...

    here are the pictures. what it might mean?http://66.7.193.50/~ue/cracks/2013-12-09.zip

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    The parapet appears to have columns placed every 3 meters (the thickness looks around the same as the height of hollow block - 20cm then), but no beam on the top. Usually horizontal and vertical thin rebars are added for reinforcement, if it is what is meant by reinforcement. I'll get some...

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    Might be also ground settling or like that, I have a house built in the similar way, there were cracks in hollow block walls, the cracks stabilized after about 2 years, but they also weren't larger than 1-2mm inside and outside in finishing maybe only 0.5mm max. And visible cracks mostly from...

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    I'll take a picture when I'm there, maybe it is just the hollow block upstands. Also significant visible cracking at the hollow block wall like structure on the top of the building (marked red) in additon to random cracking in other upstands which is being patched when happens (not correlated...

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    I may not go there for some time (a month or two), but I have rather a good idea. When I'll be there I'll take a photo. I've attached a picture. I found a photo of the building under construction (just the opposite side with the opposite column visible) and the plan where the columns were...

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    I mean I didn't notice cracks on the slab on the top of the ground floor. Sorry for the orthographic errors, I didn't know there is no edit option. The building is in an earthquake prone zone.

    Repeated pattern of symmetric concretecracks from both sides of a column from 3rd floor and upwards.

    The picture shows the building under construction, it was November 2011. October, 2012 there was no noticeable cracks. October 2013 there is significant random patch work and cracking of hollow block segments. But one column on the opposite side there is a column with different kind of...
