Our building is designed to have expansion joint. Part of structural slab is connecting to pile caps. And also, the said slab will become our basement floor. Is it safe that expansion joint will cut thru the slab joining the pile caps which is essentially part of the foundation?

thanks ron & hockey,
In the section detail, it's quite clear that no opening is provided thru the wall, which means our structural engr does not consider the opening like mechanical ducts to cut thru the wall. Otherwise, it would affect to structural integrity of the building as a...
Jed,
I appreciate your remarks, but for further infos, the wall has no door nor window. It's part of partition wall of an office. It is connected to a column and free end to the other end. What makes me concern is, if mechanical ducting will pass thru that wall, does it likely to affect...
Our 4-story bdg. is provided with shear wall designed to resist lateral loads as earthquake. Our mechanical department wants to pass a pipe ducting about 800mm in diameter thru the shear wall. However, I did not allow to do it so. Is there any reference structural codes to prohibit the opening...
Thanks jed & ron,
Further clarifications: max size of c. aggregates is 19mm only, main rebars spacing is ok, but specified tie bars is three set. Pipe of pump crete can hardly reach to lower part of the column because of these tie bars, much less if using tremie. To me 150mm slump is quite...
WE ARE USING PLASTICIZER FOR WORKABILITY OF CONCRETE POURING BUT OUR DESIGN MIX SPECIFIED SLUMP NOT TO EXCEEDS 150mm FOR COLUMNS AND BEAMS. HOWEVER, SUCH SLUMP DOES NOT WORK PROPERLY RESULTING ONLY TO HONEYCOMB. CAN WE ADJUST THE SLUMP UP TO 200mm? Please any expert can give me advise on...
Ron,
Thanks a lot..But one more thing to clarify. The shape of footing is triangle with equal three sides having dimensions of 3.2 m. Upper portion appears to be weak which is about 1/3 of thickness of 1.15 m. Our project manager wants to break the upper part only and rectify the concrete...
Proposed 4-story Building is supported by isolated footing rest on Bored Piles. A newly concrete footing was found to be inadequate due to low strength test results, so the consultant decided to remove the concrete. However, our project manager refused to do so, instead, he proposes to remove...
